Explanation:
Transcription:
Transcription is simply the process copying information from a template stand of a DNA that is used as a messenger RNA that contains info for protein synthesis. The template stand is usually the stand that goes from 5' to 3'.
It is similar to questions relating to "write the appropriate nucleotides of the second strand", but in RNA, instead of Thymine (T), it is Uracil (U). Another thing to know if you're not familiar with strand copying is that Adenine (A) goes with Thymine (T) (For RNA it is Uracil (U)) and Guanine (G) goes with Cytosine (C). Basically, just copy the 5' 3' strand and replate T by U.
So the transcription of the template
5` - C G G A T A C G G A T A T C T C G T T A A C G A T G C A C A T A G G G C T C T G A G G C A T T – 3`
is
5` - C G G A U C G G A U A U C U C G U U A A C G A U G C A C A U A G G G C U C U G A G G C A U U – 3`
Translation:
Translation is simply the proccess of decoding the transcribed strand to produce chains of amino acids or polypeptides. Each amino acid is linked to a codon, which is a set of three nucleotides on the transcribed strand. Key informations to know during translation is that it starts when the three consecutive nucleotides are A U G, which is the codon for the amino acid Methionine, and ends when approached by a stop codon which are either UAA, UAG or UGA. You will need a amino acid codon chart in order to solve this part of the question.
5` - C G G A U C G G A U A U C U C G U U A A C G ([A U G] [C A C] [A U A] [G G G] [C U C] [U G A]) G G C A U U – 3`
([A U G] [C A C] [A U A] [G G G] [C U C] [U G A])
Met, His, ile, Gly, Leu
