We identify nucleic acid strand orientation on the basis of important chemical functional groups. These are the _________ group
Alina [70]

Answer: Option B) phosphate; hydroxyl; 3'

We identify nucleic acid strand orientation on the basis of important chemical functional groups. These are the phosphate group attached to the 5' carbon atom of the sugar portion of a nucleotide and the hydroxyl group attached to the 3'

carbon atom

Explanation:

For both RNA and DNA, chemical groups such as phosphate (PO3-) attaches to the 5' carbon of the pentose sugar (deoxyribose in DNA, ribose in RNA).

While hydroxyl group (OH) attaches to the 3' carbon atom of the pentose sugar.

Thus, a nucleic acid structure structure reveals a several repeating units of nucleotides where nitrogenous base links to a pentose sugar, who in turns is linked to phosphate group
