what does a strand of dna mainly consist of
Best Answer: DNA or known as Deoxyribonucleic Acid consists of two chains, strands composed of a large number of chemical compounds, called nucleotides, linked together to form a chain.These chains are arranged like a ladder that has been twisted into the shape of a winding staircase, called a double helix.NA (Deoxyribonucleic Acid) consists of a phosphate deoxyribose backbone structure with 1 of 4 nucleotides attached to it. The nucleotides are Adenine and Thymine (always pair together) and Cytosine and Guanine (also always pairing together). Â· 7 years ago. Thumbs up.
