Answer:
Section 3.2Primary Structure: Amino Acids Are Linked by Peptide Bonds to Form Polypeptide Chains. Proteins are linear polymers formed by linking the α-carboxyl group of one amino acid to the α-amino group of another amino acid with a peptide bond (also called an amide bond).
During the second gap, or G2 phase, the cell continues to grow in size and produce proteins necessary for cell division. Microtubules, filamentous internal structures, necessary for separating the chromosome copies are made during this phase. The second internal checkpoint that determines if the cell can continue through its cycle occurs in G2. While the G1 checkpoint checks to verify DNA is error free before replication, the checkpoint in G2 confirms the new DNA is error free after replication
