The genetic counselor shows a family a DNA model to explain how their genetic test results reveal information about inherited conditions. The double helix structure contains complementary base pairs that store genetic information. What structural feature of DNA makes it most suitable for long-term genetic information storage?
Question 2 options:

DNA's single-strand structure prevents damage from cellular enzymes and environmental factors

DNA constantly changes its structure to adapt to different cellular environments and needs

Only the nitrogen bases store information; the backbone serves no functional purpose in genetics

The sugar-phosphate backbone provides stability while complementary base pairing enables accurate replication

The sugar-phosphate backbone provides stability while complementary base pairing enables accurate replication.

This double-stranded structure protects the information-carrying bases and allows faithful copying (via base-pair complementarity), making DNA well-suited for long-term storage of genetic information.
