Answer:
The correct answer is option - b. chemical structure of DNA.
Explanation:
Studying the chemical structure of the DNA molecule is comes within the molecular genetics. Molecular genetics is the subdiscipline of genetics that includes the study of function and structure at the molecular level of the genes with the help of methods of genetics and molecular biology.
The molecular genetics can help in the study of mutation, heredity, and variation with the knowledge of chromosomes and genes.
Thus, the correct answer is option B. chemical structure of DNA.
3. B
4. False

Answer:
We know the process of mitosis produces diploid cells because as a result of mitosis, identical cells are formed as the parent cell. This shows that the daughter cells are also diploid just as the parental cell.
We know the process of meiosis produces haploid cells because after fertilization, the number of chromosomes in maintained and genetic stability is achieved. The genetic stability can only be achieved if the number of chromosomes become haploid in the sex cells.
