The diagram shows the structure of DNA with complementary base pairing between strands.Bood3'CGAT౦ారG CCGCG3'5What is the benefit of this complementary nature of DNA?O It helps in controlling the amount of protein produced by the cells.O It helps in storing all the information required for the cell to function efficiently.It helps in the synthesizing of two new identical DNA strands from each parent strandO It helps in the unwinding of DNA allowing for the formation of chromosomes during mitosis

Double-stranded DNA has two strands of complementary DNA wherein Adenosine is bonded to Thymine via a double bond and Guanosine is bonded to Cytosine via a triple bond. Option - It helps in synthesizing two identical DNA strands from each parent strand. The specific form of a double helix with the pairing of not identical but complementary bases is very useful in preserving the semi-conservative nature of the replication. In any other kind of arrangement this may have been difficult. But with this particular pairing of complementary bases in the replication process, each stand can independently be a template for making another set of complementary strands along their line, and thus at the end of replication, we get two identical molecules in which one strand is old (that worked as a template) and one strand is newly synthesized DNA.Following are the incorrect choices: - It helps in controlling the amount of protein produced by the cells. The amount of protein produced by a cell has many controlling factors and pathways, complementary base pairing is not one of them. - It helps in storing all the information required for the cell to function efficiently. Information is stored in triplets and sent via mRNA which is a single strand, without complementary bases making antiparallel strand, as seen in DNA. This shows that carrying or storing information is not a function of complementary base pairing. - It helps in the unwinding of DNA allowing for the formation of chromosomes during mitosis. Any other arrangement also would have been equally easy to unwind. Hence the complementary base pairs are not the reason for this.
