Hello students.
00:01
Let us solve this question.
00:03
So this question has many sub -baths and it is given.
00:06
The dna sequence is given which holds for six amino acids.
00:10
This is the three prime end and this is the five prime end.
00:14
So the first question is what are amino acids? what are amino acids? basically what are the amino acids that are going to be formed from this sequence? so first we will write the definition of amino acids.
00:32
And then we will see what are the different amino acids that are formed.
00:35
So amino acids are nothing but there are monomers that form the protein.
00:49
So now if you look at the dna sequences.
00:52
So this is your dna sequence.
00:54
We will first have to find the mrna sequence from this, which is basically all the t's we are going to replace with you.
01:04
This will become u -u -a, u -c -t, u -c -g.
01:15
No other nucleotide sequence will be changed.
01:21
And then finally this will also remain the same.
01:24
Now what are the amino acids? these are codons for amino acids.
01:28
So u -u -a is codon for lucine.
01:33
U -c -t is codon for serene.
01:38
U -c -g is also a codon for serene.
01:42
Your gga is codon for glycine.
01:51
Your g, this is sorry, this is g -a -g, g -a -g.
01:59
This is the code for glutamic acid.
02:04
Your a -triple -a is the codon for lysine.
02:10
And this is your leucine, first one.
02:13
So this is the answer to first part.
02:15
Now there is another part to this question in which it has been asked.
02:20
Let us see what is the next part.
02:22
In the next part, it is given that thymine is replaced by uracil that we know.
02:39
Now if it is deleted, if there is deletion of the first thine, then what is going to occur? frame shift mutation will take place.
03:01
Frame shift mutation will take place.
03:06
So we have to now tell what is the change in the amino acid sequence.
03:13
So before we do that, what is frame shift mutation? in frame shift mutation there is a shift in how the dna sequence is read, meaning change in the reading frame.
03:30
Of the dna and this can happen due to as in the case deletion but can also happen due to insertion of nucleotides now if you delete the first one first t if you delete then what will become of the dna sequence t a t this will become your first codon c t then c g g g g g a, g, a.
04:12
And in the end, you will only be left with two nucleotides, which will not code for any of the protein.
04:19
So this will become, in the m -r -n -a, this will become u -a -u, this will become c -u -u, this is your c -g -g -g, a -g, and here you get a -a.
04:43
Now this one is incomplete and will not code for it will not code for any of the amino acid because you need three nucleotide sequence.
04:59
Let us see what the other are coding for amino acid...
