Question

A(n)_____ is a linear polymer of nucleotide units linked from the hydroxyl group at the 3' carbon of the pentose of one nucleotide to the phosphate group of the other nucleotide.
A)​ribonucleotide

C)​polynucleotide
D)​ketopentose
E)​aldopentose

Quizplus · Accepted Answer

The description matches the structure of a polynucleotide, which is composed of nucleotide units linked through a 3'-5' phosphodiester bond between the sugar and phosphate groups. Ribonucleotides are individual nucleotide units that make up a polynucleotide, while polysaccharides are linear chains of monosaccharide units linked by glycosidic bonds. Ketopentose and aldopentose are types of sugars that make up the pentose component of nucleotides, but do not describe the entire structure of a polynucleotide.
