The secondary structure of proteins results because of _____ bonding between molecules in the protein molecules' backbone.
topjm [15]

Answer:

Hydrogen bonding

Explanation:

The newly synthesised proteins as a result of the process of translation are linear structures formed by linear arrangement of amino acids.

The linear structure of a protein is known as the primary structure which changes its conformation and take the shape of either the helix or the pleated sheet. This helical or pleated sheet structure is known as a secondary structure.

The secondary structure is formed due to the bond formed between the hydrogen of the carbonyl group and the amino group which form the backbone of the protein structure. The hydrogen bond causes the linear polypeptide to form spiral helical or bend pleated sheet.

Thus, Hydrogen bonding is the correct answer.

9) Genetic variation is the source for evolution. Without a variety of phenotypes, there would be no differential survival upon
Firlakuza [10]

The genetic variation occurs due to induced changes to the genome from environmental factors, fertilization of two haploid gametes during gamete fusion. The correct options are D and E.

<h3>What is genetic variation?</h3>

The presence of differences in gene sequences between individual organisms of a species is referred to as genetic variation. It allows for natural selection, which is one of the primary forces driving life's evolution.

The genetic variation occurs due to induced changes to the genome from environmental factors, fertilization of two haploid gametes during gamete fusion.

Thus, the correct options are D and E.
