Charra [1.4K]

A single change or alteration in the nucleotide base of the genetic material of the cell is called a point mutation.  It can be a deletion, addition or inversion of a single nucleotide base.

In the following, the mutations that occurred are 1. C and 2. B.

<h3>How the mutation can be explained?</h3>

  • <u>Silent mutation</u> occurs in a single base of the triplet codons of the bases but the alterations do not cause an observable effect and they remain as a neutral alteration. They do not affect the function of the protein. Thus, the glycine to glycine is a silent mutation.

  • <u>Non-sense mutations</u> are caused when the single change in the nucleotide base results in the formation of the stop codon. Thus, lysine to stop codon is a nonsense mutation.

Therefore, silent and nonsense mutations are the correct options.

Sveta_85 [38]

Answer:

The correct answer will be option-C

Explanation:

The rhythm of the heartbeat is controlled by the pacemaker of the heart called the sino-atrial node.

The SA node generates action potentials which trigger the contraction and relaxation of the atrium and ventricles. The membrane potential generation initiates by the depolarization of the cell membrane when the L type of Ca⁺² ions opens up and calcium ions enter the cell.

This depolarizes the cell until the potential threshold is reached which lies between the -40 and -30 mV.

Thus, Option-C is the correct answer.
