identify the types of mutations resulting from base substitutions at different codon positions: • Mutation of 1st base: Mutant codon UCU → A.A. Mutation type • Mutation of 2nd base: Mutant codon GAU → A.A. Mutation type • Mutation of 3rd base: Mutant codon GCC → A.A. Mutation typeC:

0:00 Hello student here.

00:01 The question is given and the in this given question the sequence of mrna is given and these mrna sequence is coded into their protein.

00:10 So we have to tell about the coded sequences.

00:14 So we know the mrna having the codon and these codons in the three letter code.

00:21 And these three letter codon code for a particular amino acid.

00:25 So if we look at these original sequences, so these original sequences, so these original sequences, cuce code for the leucine.

00:32 This uce for serene and this uau for tyrosine, ccg for the proline, and this is for the cug for lucine and this is for the alenine.

00:44 So these are the three letter code for the amino acid.

00:47 So these are amino acid coded in the original sequence.

00:51 After mutation they are getting these sequences.

00:54 So this gug is coded for the valine, acg for the serene.

00:59 This a u -a -u is for tyrosine, c -cc for the proline, this for the leucine, and last one for the threonine.

01:08 Similarly, if we look at this mutation two after menstruation two, there is the cuc, which is for the leucine, and this is for c -ene, and ua -a is a stop codon.

01:20 So these is going to stop here because the stop codon is this one.

01:26 And after this, in the case of third there is this guc for the valine amino acid and this for the serene and this one for the tyrosine c c c for the proline and this uga also a stop codon so this pro amino acid synthesis going to stop at this place because it encountered the stop codon so what could be the deleterious effect of the mutation so the most deleterious effect of mutation to the gene which would be inserted or deleted.

02:15 So if there is any single nucleotide would be insertion or it could be a removal of single nucleotide...
