Structurally, DNA and RNA are nearly identical. As mentioned earlier, however, there are three fundamental differences that account for the very different functions of the two molecules. RNA has a ribose sugar instead of a deoxyribose sugar like DNA. RNA nucleotides have a uracil base instead of thymine.
When the concentration o molecules inside a cell is different form the concentration of molecules outside a cell, we can either call it hypertonic or a hypotonic solution, and the difference between the two concentrations is called a concentration gradient.
Hypertonic - name given to a solution that has a bigger concentration than the concentration in a cell.
Hypotonic - name give nto a solution that has a smaller concentration than the concentration in a cell.

Answer:
A mutation is the changing of the structure of a gene, resulting in a variant form that may be transmitted to subsequent generations, caused by the alteration of single base units in DNA, or the deletion, insertion, or rearrangement of larger sections of genes or chromosomes. Mutations in sex cells are more serious because they are heritable and affect the next generation.
Explanation:
Answer:
All of the above.
Explanation:
Allosteric protein may be defined as the protein that has multiple ligand sites and binds to the site other than the active site. Allosteric protein is involved in the regulation of metabolic pathways of the body.
Allosteric protein does not follow the Michaelis-Menton kinetics. These proteins are multisubunit protein and has the different binding sites for the effector as well as substrate molecule. These proteins are present at the committing steps of the metabolic pathways.
Thus, the correct answer is option (e).
