Which of the following is a nucleotide found in DNA? F
adenine + phosphate group + thymine
G
cytosine + phosphate group + guanine
H
deoxyribose + phosphate group + polymerase
J
deoxyribose + phosphate group + cytosin

J

Explanation

A nucleotide consists of a sugar molecule (in this case, deoxyribose), a phosphate group and a nitrogenous group. Based on this definition of a nucleotide, J would be the most appropriate answer as it lists deoxyribose (sugar molecule), a phosphate group and the nitrogenous base cytosine.

a tetrad is the foursome during meiosis made by two homologous chromosomes that have each already replicated into a pair of sister chromatids.
