4 nucleotide sequence.
00:03
And we are asked to explain this.
00:08
Now first let us see what is a single nucleotide deletion.
00:14
It is a small scale mutation since it affects a relatively small part of the gene.
00:24
It involves single nucleotide from the dna.
00:29
These mutations may lead to even.
00:32
Reversible change this mutation this single nucleotide deletion may lead to is reversible changes and altered reading frame of gene this is reversible change is the key word for our answer now let us see this diagram now next it is asked does this nucleotide deletion restore? restore means does it bring back the function of protein -poding gene? now, firstly, let us see what is protein -poding gene? it is a sequence that are transcripted into mrna and in which the corresponding mrna molecules are translated into a polypeptide chain.
01:37
Now, for example, let us see this diagram.
01:45
Here, this is pre -mrna...
