Question

select all of the following that are components of nucleotides.
check all that apply
5-carbon sugar
phosphate group
amino acid
nitrogenous base

Explanation:

Nucleotides, the building blocks of nucleic acids (DNA and RNA), are composed of three main components: a 5 - carbon sugar (deoxyribose in DNA, ribose in RNA), a phosphate group, and a nitrogenous base (adenine, guanine, cytosine, thymine in DNA; adenine, guanine, cytosine, uracil in RNA). Amino acids are the building blocks of proteins, not nucleotides. So the components of nucleotides are 5 - carbon sugar, phosphate group, and nitrogenous base.

Answer:

• 5 - carbon sugar (checked)
• phosphate group (checked)
• nitrogenous base (checked)
• amino acid (not checked)
