Hi everyone.
00:01
So this question deals with the replication transcription and translation.
00:05
So in the first part of this question, they are asking us that how do we know which basis to use when we transcribe the dna sequence to the mrna codos? okay, so we know one thing that dna is a double helical structure.
00:20
Okay, we know this thing.
00:21
So we also know that this dna is going to form what? so this dna is going to form the rna.
00:28
And this rna is formed from the dna from basically the non -coding strand of the dna, from the non -coding strand of the dna or from the template stand of the dna.
00:41
That is, it is going to, for example, if this mrna direction is in the 5 prime to 3 -prime direction, if this rna is formed in the 5 -prime to 3 -prem direction, therefore we can say that it is formed from this particular strand that is in the direction 3 -5 -prime.
00:57
Okay so for example if this dna is going to contain this sequence that is a g tc a gtc then this mrna is going to form in the 5 prime to 3 prime direction okay and the basis that are there in the rna includes a that is adenine uresil guen and cytosin in which in which this adenine is going to form double hydrogen bonds with the uracil and this guenine is going to form the triple hydration bonds with the cytosin.
01:31
So what we can write here so a is going to form double hydration bonds with the urescel.
01:37
So we can write u.
01:39
And here we can write c and this instead of t we can write here a and this c is going to form bonds with the guenine and this again a is going to form bonds with the uresil then c then a then g okay, then we can easily find out the codones, okay, the mrna codones.
02:00
Because we know one thing that these three nucleotides are going to form what? then these three nucleotides are going to form one codon.
02:08
For example, this aug is going to code for which amino acid.
02:12
It is going to code for the methionine.
02:15
It is a codone, a group of the three nucleotides, or we can say that it is a triplet.
02:20
So it is going to code for the methionine, which is an amino acid.
02:24
So we can easily find it, we can easily find out the codones and we can easily find out which trna is going to bring which amino acid with respect to the codone that are there on the mrna and after that there would be the formation of the proteins by the polymerization of the amino acids.
02:44
Okay, so this is the first part of the question.
02:47
So now coming on to the second part of this question...
