which bases are found in a strand of dna?
thymine, guanine, cytosine, uracil
guanine, cytosine, uracil, adenine
cytosine, glycine, adenine, thymine
adenine, thymine, guanine, cytosine

Explanation:

DNA (deoxyribonucleic acid) has four nitrogen - containing bases. Adenine pairs with thymine, and guanine pairs with cytosine. Uracil is found in RNA (ribonucleic acid), not DNA. Glycine is an amino acid, not a nitrogen - base in DNA.

Answer:

adenine, thymine, guanine, cytosine
