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?

The correct answer is- sequence of bases

Explanation:

Watson and Crick demonstrated that DNA is a double-stranded molecules which are joined together by hydrogen bonds between the complementary base pairs present on opposite strands.  

The genetic information is present in the DNA in the form of a sequence of bases. These base sequences are transcribed during the transcription process and translated in the translation process. During translation, the bases are expressed in the form of proteins.

The DNA can be transferred from parent to daughter cells so DNA could carry a large amount of hereditary information.

option c is the correct answer.
