Not yet to answer this question, let's talk about base pairing rules.
00:02
You remember that according to base pairing rules, adenine pairs with cyming in dna, but with ulyceling rna, and cytos in pairs with one.
00:09
In this case, you have the following question that says, the dna sequence shown below here, here you have your dna sequence, is from the middle of a protein coding gene.
00:23
So don't expect to find methionine, okay? because methion is at the beginning of the gene, but in this case, you have the middle of the gene.
00:31
Within this sequence are called for a series of four amino acids that are losing, theroning, baling, and losing.
00:39
Which number on this diagram here indicates a three end of the template strand used for this gene.
00:45
So remember that you have a template strand in a coding strand of dna.
00:50
One important feature here is that a coding strand of dna always has the same sequence as your messenger rna, with the only difference that your messenger rna has euraclylyt's set of timing.
01:00
Now, according to the genetic code that is in the table that has been provided to you, leucin can be coded by many codons in the messenger rna.
01:10
For example, by c -u -u -c, c -u -a, c -u -g, a -u -g, a -u -c.
01:15
So one of this is the coding strand, okay? so, in other words, one of these strands is the messenger rna sequence.
01:25
Now, if you look here, you have c -t -a, in the messenger rna, this is going to be equal to cua, because it'll do that in this case, we can suppose that this strand here is a messenger or is a coding strand of dna.
01:40
Okay, let's see if this strand is a coding strand.
01:44
If it is a coding strand, then it means that it is going to have the same sequence as you're a messenger rna, with the only difference that you have to change all that i means by ulysis.
01:51
So in the messenger rna you're going to have cua, and cua calls for losing...
