The genetic information resides on both strands of DNA. DNA is a double-stranded molecule, composed of two complementary strands that are held together by hydrogen bonds. Each strand consists of a sequence of nucleotides, and the two strands run in opposite directions (antiparallel).
The genetic information is encoded in the sequence of nucleotides on each strand. The nucleotides are made up of four bases: adenine (A), thymine (T), cytosine (C), and guanine (G). The sequence of these bases on one strand determines the sequence of bases on the other strand through complementary base pairing: A always pairs with T, and C always pairs with G.
The information on both strands is required because each strand serves as a template for the synthesis of a complementary strand during DNA replication and transcription. This allows for the accurate copying and transmission of genetic information from one generation to the next.
