How many individual strands is DNA composed of?
Answer (2)
DNA is a double helix, meaning there are two strands. DNA is made of chemical building blocks called nucleotides. These building blocks are made of three parts: a phosphate group, a sugar group and one of four types of nitrogen bases. To form a strand of DNA, nucleotides are linked into chains, with the phosphate and sugar groups alternating.
DNA is made up of two individual strands that form a double helix structure. Each strand is composed of nucleotides connected by phosphate and sugar groups. The complementary nature of the strands enables accurate replication of genetic information.
