Sagot :
The right answer is B.
Insertion is a genetic mutation characterized by the entrenchment of genetic material in a chromosome. The insertion size varies between a base pair and an entire sector of a chromosome moved to another. In the latter case, part of the genetic data of the first chromosome is erased. This can happen during an uneven jumping.
The embedding of nucleic bases in a gene makes it longer and shifts the reading of its data, which can modify its functioning in a harmful way, especially if the insertion occurs on the exon (fragments of an RNA primary presence in cytoplasmic RNA after splicing).
Answer: The correct answer is -
B) the insertion of a nucleotide into DNA.
Explanation:
Mutation can be described as permanent change in the genetic material ( that is DNA, deoxyribonucleic acid) of living organisms. There are primarily three different types of mutation that are base substitution, deletion, and insertion.
They can lead to change in the protein formation or inhibit the protein formation (for instance, non sense mutaion is a type of base substitution mutation in which it results in stop codon in between the sequence, which stops the protein synthesis).
Similarly, insertion mutation results when there is addition of nucleotide in the original DNA sequence.
Thus, option B) is the right answer.
