DNA Translation Question?

Question

What polypeptide sequence would be produced if only the first reading frame (as indicated by the codon spacing) of the RNA sequenceshown below was translated?

GGG_AAG_UUC_AAU_GAC_CCC_AUC_AAA

This question has been causing me a lot of grief. If anyone can lend me some clues or hints, I would be very thankful.

Regards.

Answer 1

each base can only pair in the following way:



Adenine can only pair with Uracil

Guanine can only pair with Cytosine



so GGG=CCC

and AAG=UUC

UUC=AAG

AAU=UUA

GAC=CUG

CCC=GGG

AUC=UAG

AAA=UUU



and each anti codon can only code for a specific amino acid

so, CCC=proline

AAG=lysine

UUA=leucine

CUG=leucine

GGG=glycine

UAG=STOP

UUU=phenylalanine



so the sequence would be proline, lysine, leucine, leucine,glycine, STOP, phenylalanine



the stop means that there will be two chains, one being proline, lysine, leucine, leucine,glycine and the other being just phenylalanine.

Answer 2

You want the polypeptide translation, right? I think everyone else here is thinking transcription or reverse transcription.



If this RNA is translated, you get GKFNDPIK as your polypeptide. Using a codon table, looking up GGG gives you glycine (abbreviated G). The data in a codon table was experimentally determined, so there's no way you can come up with this on your own. :)

Answer 3

A = Adenine

C = Cytosine

G = Guanine

U = Uracil



Ok so. Adenine and guanine are purines, cytosine and uracil are pyrimidines. Which means that, if Guanine is on the original sequence, it will be translated as Adenine. And if Uracil is the original, it will be translated as Cytosine. This is UNIVERSAL.



Therefore, your code should look like this.



Original: GGG_AAG_UUC_AAU_GAC_CCC_AUC_AAA

Translate: AAA_GGA_CUU_GGC_AGU_UUU_GCU_GGG



Thats it! So, practice and you will get it.



P.S. polypeptide is a code like yours with the translation at the bottom.

P.P.S. Purines and pyrimidines are just real fancy words. It just means that the former will be translated to the latter and the opposite.

Answer 4

First codon GGG is glycine (Gly)



Second AAG is lysine (Lys)



UUC is phenylalanine (Phe)



You can get the rest from the link below.

Answer 5

G=C <=

A=T <=

U=A <=

C=G <=

now just rewrite it

use the second letter

the first part would be

GGG => CCC

AAG => TTC

and so on
