Question

what base pairs are bonded with three bonds? adenine thymine cytosine guanine what are the parts to a nucleotide? deoxyribose sugar, phosphate, nitrogenous base ribose sugar, phosphate, nitrogenous base deoxyribose sugar, penicillin, nitrogenous base

Explanation:

1. In DNA, cytosine - guanine base pairs are bonded by three hydrogen bonds. Adenine - thymine base pairs have two hydrogen bonds.
2. A nucleotide consists of a sugar (deoxyribose in DNA or ribose in RNA), a phosphate group, and a nitrogenous base. Penicillin is an antibiotic and not part of a nucleotide.

Answer:

1. C. Cytosine, D. Guanine
2. A. Deoxyribose Sugar, phosphate, nitrogenous base (for DNA - if considering RNA, B. Ribose Sugar, phosphate, nitrogenous base would be correct too, but the context here seems more DNA - centric)
