why are active odorant receptor genes highly conserved but pseudogene versions of them not highly conservative? (4pts)
Active odorant receptor genes are highly conserved because they play a critical role in the sense of smell and the detection of odorants.
These genes have been maintained through evolutionary history due to their importance in the survival and adaptation of organisms. In contrast, pseudogene versions of these genes are not highly conserved because they have lost their functionality and are no longer necessary for survival. Pseudogenes are inactive copies of genes that have accumulated mutations over time, rendering them non-functional. As a result, they are not subjected to the same evolutionary pressures as active genes and are free to accumulate mutations without negative consequences.
Therefore, pseudogenes are less conserved than active genes because they do not serve a critical role in the survival or adaptation of organisms. In summary, active odorant receptor genes are highly conserved due to their critical role in the sense of smell, while pseudogene versions of these genes are not highly conserved because they have lost their functionality and are no longer necessary for survival.

the initiation of the s phase of the cell cycle depends on the functional activity of a pair of
The initiation of the S phase of the cell cycle depends on the functional activity of a pair of main answer, the cyclin-dependent kinases (CDKs) and the cyclins.
CDKs are enzymes that regulate the progression of the cell cycle, and they require binding to specific cyclins to become activated.
The levels of cyclins vary throughout the cell cycle, and the presence of specific cyclins at the start of the S phase is necessary for CDK activation and progression through the S phase.
This CDK-cyclin complex triggers the phosphorylation of target proteins that are involved in DNA replication, allowing the cell to replicate its genetic material before cell division. Therefore, the functional activity of CDKs and cyclins is crucial for the proper initiation and progression of the S phase of the cell cycle.

people with chronic liver disease frequently have elevated levels of iron in their blood. iron is needed by v. vulnificus for growth. how does it acquire iron from the host?
To acquire iron from the host, V. vulnificus both produces siderophores that enable it to scavenge iron and a hemolysin that lyses blood cells to liberate haemoglobin that contains iron.
Gram-negative bacteria called Vibrio vulnificus can lead to serious, even fatal illnesses. Three separate syndromes are brought on by V. vulnificus, including gastrointestinal tract-restricted infections, an overwhelming primary septicemia brought on by eating infected seafood, and wound infections contracted when an open wound is exposed to polluted warm seawater.
Patients with chronic liver illness and hemochromatosis usually have high iron levels, which puts them at risk for developing invasive V. vulnificus infections since the microbe needs iron stores for bacterial overgrowth. Based on their observation that iron injection in mice models resulted in a reduction in 50% lethal dose, they directly connected V. vulnificus' virulence with the availability of host iron.
V. vulnificus cannot multiply in normal human serum. As a result, it is recognized that individuals with hemochromatosis are vulnerable to infection with V. vulnificus.

the first evidence for nucleosome formation came from digesting chromosomal dna with a non-specific nuclease. gel electrophoresis of the dna after the reaction revealed: group of answer choices
The first evidence for nucleosome formation came from digesting chromosomal DNA with a non-specific nuclease. This experiment was conducted by Roger Kornberg in 1974, and it revealed that DNA is packaged into repeating units called nucleosomes.
The non-specific nuclease used in the experiment cleaves DNA at random locations. When the chromosomal DNA was digested with this enzyme, the resulting fragments were separated by gel electrophoresis. The gel electrophoresis of the DNA after the reaction revealed a ladder-like pattern of DNA fragments. This ladder-like pattern was composed of multiples of approximately 200 base pairs in length, which corresponded to the length of DNA wrapped around a nucleosome core particle.
The nucleosome core particle is composed of an octamer of histone proteins, around which the DNA is wrapped in a left-handed superhelix.
The ladder-like pattern seen in the gel electrophoresis confirmed the existence of nucleosomes and provided the first evidence for their formation. This experiment provided a significant breakthrough in our understanding of the structure of chromatin and its role in regulating gene expression. T

b.consider the real shape of a red blood cell and allow the cell to deform as it passes through a pore of radius r. assume that the red blood cell is cylindrical with hemispherical ends. taking cell membrane area as 130um2, what is the minimum r value? you will get a cubic equation for r that you need to solve numerically.
The minimum radius of the pore that the red blood cell can pass through without breaking is approximately 4.53 μm.
To solve for the minimum radius, we need to use the formula for the surface area of a cylindrical object with hemispherical ends, which is given by;
A = 2πrh + πr²
where A will be the surface area, r will be the radius, and h will be the height of the cylindrical part of the cell.
We can rearrange this equation to solve for the height;
h = (A - πr²) / (2πr)
Now, when the cell passes through a pore of radius r, it will deform to fit the shape of the pore. The minimum radius of the pore that the cell can pass through without breaking is when the surface area of the cell is equal to the surface area of the pore. Therefore, we can set the surface area of the cell equal to the surface area of the pore, which is given by:
A = 4πr²
We can then substitute this expression for A into the equation for h;
h = (4πr² - πr²) / (2πr)
h = (3r) / 2
Now, we can substitute this expression for h back into the equation for the surface area of the cell to get;
A = 2πr(3r/2) + πr²
A = 3πr²
Finally, we can substitute the given cell membrane area of 130 μm^2 into this expression and solve for r;
130 μm² = 3πr²
r² = 130 μm² / (3π)
r ≈ 4.53 μm

The false statement about phosphorylase a and phosphorylase b or their relationship to each other is that phosphorylase a is inhibited by glucose. In reality, phosphorylase a is activated by phosphorylation and inhibited by ATP and glucose-6-phosphate. Phosphorylase b, on the other hand, is the non-phosphorylated form of phosphorylase a and is activated by AMP.
To avoid confusion with phosphatases (hydrolases) and kinases (phosphotransferases), phosphorylases are enzymes that catalyze the addition of a phosphate group from an inorganic phosphate (phosphate + hydrogen) to an acceptor. A phosphate group is removed from a donor by a phosphatase using water, while a phosphate group is transferred from a donor (often ATP) to an acceptor by a kinase.
The more active R form of glycogen phosphorylase, phosphorylase a, is created by phosphorylating the less active R form, phosphorylase b, with the help of AMP. The inactive T form is either dephosphorylated by phosphoprotein phosphatase with inhibition by ATP and/or glucose 6-phosphate, or it is phosphorylated by phosphoylase kinase and blocked by glucose. Dephosphorylation produces free inorganic phosphate ions, whereas phosphorylation uses ATP.

and be sure to answer the lesson question: "How does
natural selection change the phenotypes within a
population over time?"
When a phenotype generated by particular alleles helps animals survive and reproduce more than their contemporaries, natural selection may boost the number of the advantageous alleles from a single generation to the next.
Natural selection alters phenotypic in what ways?The effect of natural selection upon single-gene traits can modify allele frequencies and, as a result, phenotypic frequencies. Natural selection on polygenic characteristics can have three effects on phenotypic distributions: directional selection, stabilisation selection, and disruptive selection.
How does the process of natural selection affect population growth over time?Natural selection is an evolutionary mechanism. Organisms that are better adapted to their surroundings are able to prosper and pass on the DNA that helped them thrive. Species change and split as a result of this process.

in a recombinant dna cloning experiment, how can we determine whether dna fragments of interest have been incorporated into plasmids and, once host cells are transformed, which cells contain recombinant dna ? select all that apply. in a recombinant cloning experiment, how can we determine whether fragments of interest have been incorporated into plasmids and, once host cells are transformed, which cells contain recombinant ?select all that apply. bacteria may lose resistance to certain antibiotics depending on the location of the dna insert. when dna fragments of interest have been incorporated into a plasmid, the result is a change in the function of a gene or genes in the plasmid. the bacterial host chromosome will increase in size because it will incorporate the plasmid that was inserted. in the presence of x-gal, a medium-driven color change is observed in bacteria that contain a recombinant plasmid.
We can determine whether DNA fragments of interest have been incorporated into plasmids by : change in the function of gene or genes in the plasmid, antibiotic resistance, increase in host chromosome size, and color change in the presence of X-gal.
How do you determine whether DNA fragments of interest have been incorporated in plasmids?Following options can be used to determine whether DNA fragments of interest have been incorporated into plasmids and which cells contain recombinant DNA:
A change in the function of a gene or genes in plasmid: When DNA fragments of interest are incorporated into a plasmid, they may alter function of one or more genes within the plasmid.
Antibiotic resistance: Some plasmids carry antibiotic resistance genes, which can be used as selectable markers to identify cells that have taken up recombinant plasmids.
Increase in host chromosome size: When a plasmid is inserted into bacterial host, the host chromosome may increase in size due to addition of the plasmid DNA.
Color change in the presence of X-gal: X-gal is a chromogenic substrate that is commonly used in cloning experiments to detect the presence of recombinant plasmids.
