Question

Quizplus · Accepted Answer

Nucleotides are the monomers that make up nucleic acids such as DNA and RNA. DNA is made up of four different nucleotides: adenine (A), guanine (G), cytosine (C), and thymine (T). Therefore, A is the correct answer as it correctly identifies nucleotides as the building blocks of DNA.

Answer: B, C, D are incorrect 
 B is incorrect because there are only 5 naturally occurring nucleotides. C is incorrect because nucleotides are joined together by phosphodiester bonds, not peptide bonds. D is incorrect because nucleotides can be single or double-stranded, but DNA is double-stranded while RNA is single-stranded.
