Answer 2

"The bases in nucleotides are attached to a pentose sugar moiety by a glycosidic linkage" is correct.

Nucleotide:

• Nucleotides are organic compounds made up of phosphate and nucleoside.
• They function as monomeric units of the deoxyribonucleic acid and ribonucleic acid polymers, which are both crucial macromolecules for all kinds of life on Earth.
• One of the structural elements, or building blocks, of DNA and RNA, is the nucleotide.
• A nucleotide is made up of a base (one of the four substances adenine, thymine, guanine, and cytosine), a sugar molecule, and a phosphoric acid molecule.
• Adenosine monophosphate (AMP), guanosine monophosphate (GMP), and cytidine monophosphate are examples of nucleotides containing only one phosphate group (CMP).
• In rapidly dividing stages, nucleotides are particularly important for DNA replication and RNA transcription.
• Additionally necessary for ATP and GTP production in cells, nucleotides have a variety of additional metabolic roles.
