Question

The transmission of genetic material from one generation to the next is necessary for the survival of a species. Which statement describes one property that helps to ensure the reliable transmission of genetic information in living organisms?
A) RNA uses a nucleotide base called uracil to distinguish itself from DNA.

B) The complementary base pair rules.

C) The two strands of a DNA molecule cannot be separate.

Answer 1

Answer:

The correct answer would be B) The complementary base pair rules.

DNA serves as the genetic material in most of the living organisms and is transmitted from parents to their offspring.

It is like blue print of the cell which contains all the necessary information required for the functioning and regulation of cell in the form of nucleotide sequences.

Generally, DNA consists of two strands which are complementary in nature i.e. purine base pair with its specific pyrimidine (adenine always base pair with thymine and guanine always base pair with cytosine).

This property of DNA is of utmost importance in the process of DNA replication as daughter DNA strand is formed on the basis of complementary base pair of the template strand.

It ensures that correct DNA sequence is produced for transmission to the offspring or daughter cell.
