Assertion : DNA undergoes replication. Reason : DNA contains cytosine and thymine as pyrimidine bases.
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but Reason is correct.
Explanation:
The genetic information of the cell is contained in the sequence of base \(\mathrm{A}, \mathrm{T}, \mathrm{G}\) and \(\mathrm{C}\) in DNA molecule. When a cell divides, DNA molecules replicate and make exact copies of themselves so that each daughter cell will have DNA identical to that of the parent cell. Reason is also correct but not the correct explanation of assertion. So, option (2) is correct.

Statement A : DNA is responsible for maintaining the identity of different species of organisms over millions of years. Statement B : DNA molecule is capable of self duplication during cell division and identical DNA strands are transferred to daughter cell.
1 Statement A is correct but Statement B is incorrect.
2 Statement A is incorrect but Statement B is correct.
3 Both Statements are correct.
4 Both Statements are incorrect.
Explanation:
DNA is the chemical basis of heredity and may be regarded as the reserve of genetic information. DNA is exclusively responsible for maintaining the identity of different species of organisms over millions of years. A DNA molecule is capable of self duplication during cell division and identical DNA strands are transferred to the daughter cells.

1 Ribose
2 Gene
3 Nucleoside
4 Nucleotide
Explanation:
