Question

10. Which process helps to preserve the genetic information stored in DNA during DNA replication?

A. The replacement of nitrogen base thymine with uracil.
B. Enzymes quickly linking nitrogen bases with hydrogen bonds.
C. The synthesis of unique sugar and phosphate molecules for each nucleotide
D. Nucleotides lining up along the template strand according to base pairing rules.

Answer 1

Nucleotides lining up along the template strand according to base pairing rules process helps to preserve the genetic information stored in DNA during DNA replication

Option D

Step-by-step explanation:

The DNA is a semi conservative molecule from the genetic information storing point of view. The genetic information is stored there in form of the alignment and arrangement of the nitrogen bases. These nitrogen bases are replicated just in order to conserve the genetic information.

During protein synthesis, same nitrogen bases get denoted in the RNAs and this gives the particular protein which is required in the body. No molecule present in the body can destroy the DNA and its alignment. It’s conserved as long as no external molecule or force destroys it. So it’s conserved in a very safe way.
