DNA Synthesis

In preparation for cell division, the cell makes a replica of its entire DNA. This happens during the S, or synthesis, phase of the cell cycle. Mitosis is the division of one cell into two cells that each has a nucleus and the same amount of DNA as the original cell.

in the gel electrophoresis lab, you determined the ________ of three different dna samples.

Answers

In the gel electrophoresis lab, you determined the genotype of three different DNA samples.

Gel electrophoresis is a process that allows you to separate fragments of DNA based on size. You place different size fragments of DNA into a gel, then apply current to the buffer surrounding the gel, the DNA will travel through the gel but move at different speeds based on the different fragment sizes. Larger fragments of DNA will move slower than smaller fragment sizes.

Let consider two different alleles:

the bigger allele -- Athe smaller allele -- a

The bigger allele happens to contain a restriction site that is allowed to be cleaved by a restriction enzyme while the smaller allele has a mutation in the restriction site that means that it will not be recognized and cleaved by that same restriction enzyme.

Let us remember that the person will have two copies of this gene and can be:

H0m0zygous dominant AAh0m0zygous recessive aaheterozygous Aa

An individual with h0m0zyg0us AA only have versions of the gene that will be cut by the restriction enzymes, each allele producing a small fragment of DNA and a medium-size fragment of DNA

An individual with the genotype aa only has the version of the gene that does not have the restriction site and therefore does not get cut by the restriction enzyme. The DNA sample from this individual will have a single larger fragment of DNA.

When you isolate DNA from heterozygous Aa, half of the DNA isolated has the allele with the restriction site that gets cut into two fragments while the other half will have the allele that does not have the restriction site and remains whole when a restriction enzyme is added.

Therefore, we can conclude that in the gel electrophoresis lab, you determined the genotype of three different DNA samples.

Although we consume different foods, the parts are eventually used in cellular respiration. Does it matter if they originate from crickets or cows or candy bars?

Answers

Given what we know about biological processes, we can confirm that it does not in fact matter where the nutrients come from in terms of cellular respiration.

We consume food to provide the energy we need to function on a daily basis, for this, we may reach for an apple or opt for a candy bar. However, this is irrelevant on a cellular level. Cells do not eat the food the way that we consume them.

They use a process known as cellular respiration to change the food into energy to be used by cells. The most important of this process is the transformation of high-level sugars into simple sugars like glucose and other monosaccharides.

how do mitochondria generate and store the energy used to produce most of the atp made during aerobic respiration

Answers

Answer:
By generating a ionic (electrochemical) gradient

Answer:

The citric acid or Krebs cycle processes in the matrix of mitochondria produce a molecule called NADH. NADH is then converted to adenosine triphosphate by enzymes buried in the mitochondrial inner membrane (ATP). Energy is stored in the form of chemical bonds in ATP.

Explanation:

During aerobic respiration, how is ATP created in the mitochondria?

Oxidative phosphorylation produces the majority of the ATP produced by aerobic cellular respiration. By pumping protons across a membrane, the energy released by the O2 is utilized to create a chemiosmotic potential. This potential is subsequently used to activate ATP synthase, which converts ADP and phosphate groups into ATP.

What is the mechanism by which mitochondria store energy?

Mitochondria (plural: mitochondrion) are membrane-bound cell organelles that provide the majority of the chemical energy required to fuel the cell's metabolic activities. Adenosine triphosphate is a tiny molecule that stores chemical energy created by mitochondria (ATP).

What is ATP's energy storage mechanism?

The energy currency of the cell is ATP, or adenosine triphosphate. It retains the energy created during cellular respiration when glucose is oxidized. Energy is stored in the form of high-energy phosphate bonds, which are broken to release energy. Energy is released when ATP is broken down into ADP and Pi.

Answer:

Venules carry deoxygenated blood. All blood in humans is bright red when oxygenated, but, a darker red when deoxygenated. Deoxygenated blood is darker due to the difference in shape of the red blood cell when oxygen binds to haemoglobin in the blood cell (oxygenated) versus does not bind to it (deoxygenated).

why do x-linked conditions appear more frequently in males than in females?

Answers

Answer:

Because, with females, who have two x-chromosomes, meaning both parents (mother and father) have to pass down alleles for the condition, and males only need one parent (mother) to pass down the condition for the male to have the mutation

X-linked conditions appear more frequently in males than in females because:-

In males there is only one X chromosome.Any X linked condition will appear in males as there will no other X chromosome to dominate it.In female there are two X- chromosome. If any one of the two X chromosome has defect other chromosome will dominant it and will the female will act as a carrier.

What are X linked disorder?X-linked disorders are caused by variants in genes on the X chromosome, one of the two sex chromosomes in each cell. In males who have only one X chromosome, an alteration in the only copy of the gene in each cell is sufficient to cause the condition.

Cyanidin is a compound that is sensitive to pH. Cyanidin is found in plants such as hydrangeas, cornflowers, and the vegetable rhubarb. Cornflowers are blue because the cornflowers sap is basic and cyanidin turns blue in the presence of bases. Rhubarb contains an acid called oxalic acid. This affects the cyanidin and causes the red color found in rhubarb. Other plants that contain cyanidin are cherries, raspberries, and strawberries.
