Mutation is the change in the sequence of basis.
00:08
Now this can happen either in the dna or rna.
00:15
There are two major types of mutation.
00:19
One is the germline mutation and the other one is the somatic mutation.
00:26
Now germline mutation occurs in the.
00:30
Gametes or mutation occurs inside the gametes whereas somatic mutation occurs in all the other cells except for the gametes now there is a type of mutation called point mutation where the changes occurs in a single nucleotype now this point mutation comprises of another mutation called as the substitution mutation.
01:03
Substitution mutation is where one base pair is substituted for another base pair.
01:12
Now there are a few types under substitution which are nonsense mutations, silent mutations and miss sense mutation.
01:27
Sorry, the correct spelling is this for miss sense mutation.
01:35
Now let us consider missons mutation type.
01:39
In this type, one nucleotide, let's say nuc in short, is substituted and a different codon is formed as a result and this codon that is formed codes for a different amino acid.
01:56
For example, instead of a .eg, ag, agg is produced.
02:05
That is, this a is replaced by this g base.
02:09
Hence, rg9 will be produced instead of lysine...
