Mutations are the changes produced in the nucleotide sequence of the genome.
There are four main types of mutations
Substitution
Insertion
Deletion
Duplication.
<h2>_____________________________________</h2><h3>DELETION:</h3>A small segment of chromosome mat be missing. This condition is known as deletion.
For example, Normal chromosome has A B C D E F G. If deletion mutation occurs then mutated chromosome has A D E F G and B C got deleted.
<h2>_____________________________________</h2><h3>DUPLICATION:</h3>In this condition, a part of chromosome present in exec ess to the normal chromosome.
For example, Normal Chromosome has A B C D E F G. If duplication mutation occurs, then mutated chromosome had A B C B C D E F G and B C is duplicated.
<h2>_____________________________________</h2><h3>SUBSTITUTION MUTATION:</h3>Substitution is a type of mutation where one base pair is replaced by a different base pair.
For example, in the sequence CAAGT, if C replaces G, it is a substitution mutation.
<h3>INSERTION MUTATION:</h3>In genetics, an insertion is the addition of one or more nucleotide base pairs into a DNA sequence.
For example, in the sequence CAAGT, if extra base G gets inserted after C, the new sequence would be CGAAGT.
<h2>_____________________________________</h2>Both substitution and insertion mutations change the position of nucleotide thus, the type of amino acid.
