Question

What term is applied to the gene mutation where a base is replaced by another base
A. Duplication
B. Aneuploidy
C. Euploidy
D. Substitution

Answer 1

Hint: Gene mutation is referred to as the permanent alteration in our DNA sequence. This sequence A gene mutation is a perpetual adjustment in the DNA grouping that makes up a gene, with the end goal that the succession varies based on what is found in the vast majority. Mutations range in size; they can influence anyplace from a solitary DNA building block (base pair) to a huge fragment of a chromosome that incorporates different genes.

Complete answer:
-Duplication is a sort of mutation wherein a part of genetic material or a chromosome is copied or reproduced, bringing about different duplicates of that locale.
-Aneuploidy is the presence of an extra number of chromosomes in a genome, for instance, a human cell having 45 or 47 chromosomes rather than the typical 46.
-Euploidy is the increase of at least one complete arrangement of chromosomes.
-A substitution is a reaction of mutation that involves the replacement of one base for another (i.e., an adjustment in a solitary "synthetic letter, for example, changing an A to a G). Along these lines, the right answer is 'Substitution'. A substitution is a reaction that denotes the replacement of one base pair with the other. For example, consistently every cell in your body misfortunes around 1,000 nucleotides from the DNA spine. These nucleotides tumble off because of the cycle of depurination. During the time spent supplanting them, the proteins that deal with the DNA commit an error around 75% of the time, because there are 4 nucleotides to browse. Different proteins must tag along after and check the DNA for mistakes. On the off chance that they miss the replacement mutation, it might remain and be imitated.
Hence, option D is correct, i.e., Substitution.

Note: Another factor that can drive a replacement mutation is deamination, the cycle by which amino gatherings corrupt off of nucleotides. One of the main ways the protein apparatus can separate between nucleotides is the amino gatherings connected to them.
