Question

It became apparent to Watson and Crick after completion of their model that the DNA molecule could carry a vast amount of hereditary information. Which of the following characteristics of DNA is responsible for this?
A) Sequence of bases
B) Phosphate -sugar backbones
C) Complementary pairing of bases
D) Side groups of nitrogenous bases
E) Different five-carbon sugar

Answer 1

Answer:

The correct answer is option A) "Sequence of bases".

Explanation:

Even though DNA most of the time is comprised entirely of only four different nucleotide bases (adenine, thymine, guanosine and citosine), it is the sequence of these bases that allows DNA to carry a vast amount of hereditary information. The genes that carry the hereditary information are translated according to the sequence of the DNA bases. The information is translated by triplets of bases (codons) that correspond to different amino acids that are added to new synthesized proteins during translation.
