Answer:
The options are
A. secondary structure ... hydrogen bonds
B. secondary structure ... peptide bonds
C. tertiary structure ... hydrogen bonds
D. primary structure ... covalent bonds
E. tertiary structure ... covalent bonds
THE CORRECT ANSWER IS A.
A. secondary structure ... hydrogen bonds
Explanation:
The secondary structure of a polypeptide shows the localized regions of its organised structure being upheld by hydrogen bonds among the major groups
-NH and C = O
At the same time, it inhibits the hydrogen bonds of the side chains from influencing the reaction process.
The polypeptide secondary structure shows the dexterity to curl or fold as sustained by the polypeptide chains.
3rd Choice. It describes a processed known as crossing over which results in genetically distinct daughter cells.
