Question

which of the following provides dna with the capacity to serve as the carrier of biological information?
a. its three - dimensional shape
b. its double - stranded structure
c. its arrangement of nucleotides
d. its sugar - phosphate backbone

Explanation:

DNA's nucleotide arrangement encodes genetic info. Different sequences (nucleotide order) carry different biological instructions. The three - dimensional shape (A) helps in functions like replication but doesn't carry info. The double - stranded structure (B) aids in stability and replication. The sugar - phosphate backbone (D) provides structural support. Only the nucleotide arrangement directly serves as the carrier of biological information.

Answer:

C. Its arrangement of nucleotides
