Question

the genetic information is coded in dna by the ________. a) regular alteration of sugar and phosphate molecules b) three - dimensional structure of the double helix c) arrangement of the histones d) sequence of the nucleotides

Explanation:

The genetic information in DNA is stored in the sequence of nucleotides. Nucleotides are the building - blocks of DNA, and different sequences code for different proteins and traits. The sugar - phosphate backbone provides structural support but does not code for information. The three - dimensional structure of the double helix is related to its stability and function in replication and transcription, but not the coding of information. Histones are involved in DNA packaging, not coding genetic information.

Answer:

D. sequence of the nucleotides
