Answer:
there are some differences though. ...
Explanation:
Normal red blood cells slide easily through narrow blood vessels. In sickle cell disease, many red blood cells change to a crescent shape like a slender moon. Crescent-shaped blood cells cause blockages in blood vessels. These blockages decrease the transport of oxygen. People with sickle cell disease often have sharp pains due to the lack of oxygen in parts of the body.

The sickle cell version of the gene that causes sickle cell disease is recessive. Suppose that two parents with no symptoms have a child with sickle cell disease. What genes did the child inherit from the parents?
Answer:
C- the child must have inherited the gene from both parents.
Explanation:
Both parents could carry the trait and have no symptoms, but both parents passed it down to their child causing the child to have sickle cell anemia.

Bacterial DNA is a double-stranded helix that has to ___________ its strands during replication. The _______ of DNA strands at the replication fork creates twists farther down the helix that need to be ______ by DNA _______. Ciprofloxacin ______ this enzyme to block DNA synthesis and stop the deadly bacteria from growing.
Answer:
Bacterial DNA is a double-stranded helix that has to separate its strands during replication. The unwinding of DNA strands at the replication fork creates twists farther down the helix that need to be relaxed by DNA gyrase. Ciprofloxacin inhibits this enzyme to block DNA synthesis and stop the deadly bacteria from growing.
Explanation:
DNA which stands for deoxyribonucleic acid is the molecules that stores genetic information in most living organisms. For successive reproduction to take place as well as growth to occurs in organisms, the genetic information stored in the DNA must be copied into new cells. This is achieved through the process of DNA replication.
DNA is a double-stranded molecule that is helical in shape. For replication to occur, the double strands has to be separated so that the information stored within can be accessed and then copied. DNA helicases are enzymes which are essential during DNA replication because they separate double-stranded DNA into single strands allowing each strand to be copied. The unwinding of DNA strands at the replication fork creates twists farther down the helix that need to be relaxed otherwise, the DNA strands will break. The enzyme responsible for relaxation these twists is known as DNA gyrase. Thus, any drug like Ciprofloxacin than inhibits DNA gyrase will block the DNA replication process in bacteria thereby stopping the growth of the bacteria.
Bacterial DNA is a double-stranded helix that has to separate its strands
during replication. The unwinding of DNA strands at the replication fork
creates twists farther down the helix that need to be relaxed by DNA gyrase.
Ciprofloxacin inhibits this enzyme to block DNA synthesis and stop the
deadly bacteria from growing.
The antibiotic referred to as Ciprofloxacin acts on the DNA of the bacteria
and it does this by inhibiting the enzyme that is required for DNA
synthesis. This stops replication and the anthrax bacteria from growing and
forming new organisms.

Stem cells undergo a process known as differentiation in order to become specialized. Specialized cells do not revert back into their undifferentiated form once they have matured. Nucleic acids play a role in the process of differentiation. Which statements describe the relationship between nucleic acids and differentiation? Select ALL that apply.
A) Genes within the genome tend to remain inactivated until their gene products are needed.
B) Once they are differentiated, cells contain additional DNA that programs the cells to be specialized.
C) All cells in an organism, whether differentiated of not, contain a complete genome with the exact same genes. Hindi
D) Stem cells remove part of their genome once they are differentiated so that unnecessary genes cannot be expressed.
E) Transcription factors are present in certain cells that cause specific genes to be transcribed in differentiated cells.
A
C
E
(Trust me)
Explanation:
The differentiated cell has specific transcription factors that are present in the cell and cause specific genes to be transcribed. Option E is the correct answer.
What is cell specification?Cell specification is the process by which a cell determines its fate. After specification, a cell's gene pattern changes. Some genes that are present in euchromatin regions are expressed, and as a result, this cell expresses specific proteins and RNA.
After the zygote is formed, it undergoes a cleavage process to form multiple cells by mitosis. The cells then specify and receive their fate, such as some converting into nervous cells, others into epithelial cells, and still others into blood cells.
This change in structure and function is due to the expression of special genes in DNA. Though all cells have the same genetic content, some genes are present in euchromatin regions and some genes are present in heterochromatin regions. Genes of euchromatin are expressed.
Hence, option E is the correct answer, as the cell produced specific transcription factors.

During DNA replication, which of the following components is not required?
Answer:
im not sure, but i think its single-stranded
Explanation:
The study of a gene is called genetics.
The question is incomplete kindly provide it with the option for a better understanding of the topic.
The duplication or making of new DNA from the older DNA is called replication.
The process of replication required various enzymes and another nucleotide to make a new DNA.
In my opinion, the thing which is not required to the process of replication is RNA polymerase as it is required to duplicate the RNA not DNA.
Hence, the correct answer is RNA polymerase.

Explanation:
Given that,
The object moves from 0 to 15 m.
Displacement = 15 m
Suppose the graph shows this force as a function of the position of the object
We need to calculate the work done
According to graph,
W = area under the graph from 0 to 15
Where, h = height
b = base
Put the value into the formula
Hence, The work done by the force is 150 J.
You are interested in understanding the regulation of nuclear lamina assembly. To create an in vitro system for studying this process you start with partly purified nuclear lamina subunits to which you will add back purified cellular components to drive nuclear lamina assembly. Before you start doing experiments, your instructor suggests that you consider what type of conditions would be most amenable to the assembly of the nuclear lamina from its individual subunits in vitro. Which of the following additions do you predict would be most likely to enhance the assembly of the nuclear lamina?
a. addition of phosphatase inhibitors
b. addition of ATP
c. addition of a concentrated salt solution that is 10 times the concentration normally found in the nucleoplasm
d. addition of protein kinase inhibitors
Answer:
d. addition of protein kinase inhibitors
Explanation:
The nuclear lamina is a structure composed of intermediate filament type proteins that is located between the inner nuclear membrane and the peripheral chromatin of eukaryotic cells. The nuclear lamina is involved in diverse cellular processes including, among others, nuclear/chromatin organization, control of the cell cycle, differentiation, DNA replication, transcription, etc. It is known that the nuclear lamina disassembles during mitosis and post-translational phosphorylation at specific residues of the nuclear lamina proteins modulate the polymerization state of this lamina during the cell cycle. For example, in chicken, it has been shown that protein kinase C phosphorylation inhibits the nuclear import of lamin B2, a nuclear intermediate filament protein.

Mutation comes from the Latin word mutare,
meaning "to change." How can mutations change an organism's traits?
Answer: Mutation can affect an organism by resulting to a change in the number and structure of chromosomes (chromosomal mutation). A typical example of this type of mutation is Down's syndrome where the individual contains 47 instead of 46 chromosomes.
Mutation can also result to a change in the nucleotide sequence of the DNA molecule in a particular region of a chromosome(Gene mutation) an example of genetic mutation is sickle cell anemia
