Hello students.
00:01
So today's question is about they have given us two dna templates and we have to find the mrna which is going to be transcribed, which is going to be transcribed from that dna and we have to find what kind of condone they are going to make and we have to find the proteins that is going to be translated from that particular dna.
00:23
But we need to keep a few things in mind about the start and stop cardone.
00:30
We have to.
00:30
To start the protein only when a -u -g comes because this is the start codone which is for methionine which is for methionine and we have to stop translating our protein when comes u -a -u -a -u -a -g or u -g -a if any of these three codones come we have to stop our protein at that time so another other than that we know that dna contain four for basis is a t, g c and in which a is going to pair with the t and g is going to pair with c.
01:07
But there is little change in the rna.
01:11
So in our mrn strand t is replaced by u, which is for ural.
01:19
So whenever a is in the dna strand, so euracil is going to bind that particular adenine, not thymine.
01:27
So let's make the mrn strand at first.
01:32
So first is the for a, it is going to be u.
01:36
For t it is going to be a, u, g, c.
01:41
Then again, u, u, u, then a, g, g, c, then u, g, c, then ua, g c, g c, then ua, g c, g c, c, c, c, c, c, c, c.
01:55
G c for a it is u for t it is a for c it is g for g it is c c now we need to know where is a u g so in this strand here is a u g a u g which is going to be our start codone so here we have methionine after that it is c u after that is it is u a g so we are not going to translate any further because it is one of our stop codone...
