Answer:
B.) Replication fork
Explanation:
The replication fork is the point at which two strands of DNA separate via DNA helicase.
The origin of replication is the site on a singular DNA strand where replication begins. Here, complementary nucleotides begin bonding to the single-stranded DNA via DNA polymerase.
The replication bubble is created when DNA helicase separates a DNA strand. The DNA helicase does not separate the entire strand, but rather opens only certain sections at one time. This creates a "bubble" in the DNA strand where replication will take place.
Okazaki fragments are formed on the lagging strand of the single-stranded DNA. Because DNA is only created from the 5' to 3' direction, RNA primase must reposition itself after adding a primer (made of nucleotides). DNA polymerase then fills in these fragments with more complementary nucleotides in small sections.

<h3>What is
b-vitamin?</h3>
B vitamins are a group of water-soluble vitamins that are crucial for red blood cell production and cell metabolism. Despite having names that sound similar (B1, B2, B3, etc.), these vitamins are chemically different substances that frequently coexist in the same foods. Dietary supplements that include all eight are typically referred to as vitamin B complexes. The exact number or name of each vitamin, such as B1 for thiamine, B2 for riboflavin, and B3 for niacin, is used to identify individual B vitamin supplements. Some substances, like pantothenic acid, biotin, and folate, are better known by their names than by their chemical names.
Each B vitamin either functions as a cofactor (usually a coenzyme) for important metabolic processes or functions as a precursor required to produce one.

Nucleotides can be radiolabeled before they are incorporated into newly forming DNA and, therefore, can be assayed to track their incorporation. In a set of experiments, a student-faculty research team used labeled T nucleotides to study the incorporation of labeled nucleotides into a culture of lymphocytes. They found that the lymphocytes incorporated the labeled nucleotide at a significantly higher level after a pathogen was introduced into the culture. they might conclude from this observation is that the Infection causes lymphocytes to divide more rapidly
- Lymphocytes is a type of immune cell produced in the bone marrow and present in the blood and lymphatic tissue. B lymphocytes and T lymphocytes are the two main types of lymphocytes. T lymphocytes help eliminate tumour cells and govern immune responses, whereas B lymphocytes produce antibodies. A lymphocyte is a white blood cell type.

Bar graphs show patterns in data with variables that change over time; Whereas pie charts, show data as parts out of a whole, (such as 100%).
