Question

Consider a DNA coding strand with the following sequence: 3’-C T T C A T A G C T C G-5’.

Use the genetic code to determine the corresponding amino acid sequence of the translated protein.

DNA Coding Strand: 3’- C T T C A T A G C T C G -5’

mRNA Strand:

Protein Sequence:

Accepted Answer

Okay, everyone, consider a DNA coding strand with the following sequence. Use the genetic code to determine the corresponding amino acid sequence of the translated protein. Okay, so we're given a DNA coding strand were asked to find the Mara and then the sequence of amino acids. All right, so here is our DNA coding strand. Now, let's find the mRNA Strand. But be careful. They gave us the coding strand, not the template Strand. So is the Marna going to be anti parallel to the coding strand? No. It's gonna have the same directionality is the coding strand. Because if you remember, the RNA polymerase uses the template strand of DNA as a template to make the Marna in the Marna is anti parallel to the template strand. But so is the coding strand. That means that the Mara and the coding strand have the same directionality, and they should have the same sequence of nucleotides. Except RNA has euros ill, while DNA has fine means. So just remember those be careful, because sometimes they could give you the coding strand in a particular question. And sometimes they could give you a template strand. Just keep that in mind. and we have a coding strand. So we know that the Marna should have the same directionality. So it should start with three. Prime, just as the coding strand does an end in five prime, just as the coding strand does. So now we're just going to write the same bases down as seen in the coaching strand. Except all of these teas are going to be changed to use. So we have See you. You see a u A g c u c Got a little close here. See G five prime. So that is the code of the M r N A strand. So now we just have to go through the different code on and figure out the associative amino acids. So let's start with the very first code on on the three prime end. See you, you. So we go over to our table, we find the first letter, we find the second letter. C u u is right here. So that means we have a loose seen as the first amino acids L E U. So that's the first one. So now let's move on to the second one. C a U C A. You so that is a histamine. So H i s, then So a g c. That's movies a G See searing. And then we have you see G. You see g another searing. All right, so that is going to be the sequence of amino acids associated with this particular M r n a strand and this coding strand. Okay, everyone, let's move on to our next video.
