MUTATIONS

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
When a nitrogen base is added to a gene, this is called a ____ mutation.
A
deletion
B
insertion
C
substitution
D
point
Explanation: 

Detailed explanation-1: -An insertion changes the DNA sequence by adding one or more nucleotides to the gene. As a result, the protein made from the gene may not function properly.

Detailed explanation-2: -An insertion mutation, also known as a gene insertion or DNA insertion, is a type of mutation where additional nucleotides are inserted into the DNA. DNA is the genetic material of the cell. It contains all of the instructions for cell structure and function.

Detailed explanation-3: -One type of frameshift mutation is called insertion. As the name implies, an insertion occurs when a single nitrogen base is accidentally added in the middle of a sequence. This throws off the reading frame of the DNA and the wrong amino acid is translated.

Detailed explanation-4: -Insertion An insertion, as related to genomics, is a type of mutation that involves the addition of one or more nucleotides into a segment of DNA. An insertion can involve the addition of any number of nucleotides, from a single nucleotide to an entire piece of a chromosome.

Detailed explanation-5: -Insertions and deletions An insertion mutation occurs when an extra nucleotide is added to the DNA strand during replication.
