answer is b
Explanation:
aa in the anaphase of cell division crossing over and random assortment of genes happen so the genes are getting mixed up together
Answer:
The correct answer will be option-Base analog
Explanation:
5-bromodeoxyuridine is a synthetic nucleoside which is formed by deaminating the 5-Bromodeoxycytidine.
The BrdU once incorporated in the DNA of replicating cell during S phase binds the adenine which shows that it replaces the thymidine which usually binds the adenine.
Since BrdU binds the adenine, therefore, it acts as the analogue of the thymidine and also can cause mutations thus acts as a mutagen.
Therefore, it acts as a base analog and thus is the correct answer.
Answer;
To protect the rest of the esophagus from sharp food particles and stomach acid.
Explanation;
The mucosa is the innermost layer, and functions in absorption and secretion. It is composed of epithelium cells and a thin connective tissue.
It contains specialized goblet cells that secrete sticky mucus throughout the GI tract, that prevents the corrosion of the stomach walls and esophagus from sharp food particles and the acids from the stomach.
D = m/V
m = 75g
V = 4 x 4 x 4 = 64 cm^3
d = 75/64 = 1 11/64 g/cm^3
<span>To answer this question, one must first set up a test to determine how many different genes are contributing to the wingless phenotype in the mutant fly strains. Upon setting up the test, it is determined that 5 different genes are contributing.</span>
