Hello everyone so in this question we are given a sequence of dna sequences and we are here asked some question.
00:11
So the question number first one here asked us to identify the start and stop codons in the given dna sequences.
00:21
So the start codon is atg which codes for methionine and the stop codons are taa, tag and tg.
00:51
So this is the stop codons.
00:55
So in the given dna sequences the from the given dna sequences we can see that the start codon is atg and the stop codon here given is taa which is seen in the bottom strand.
01:14
So the sequence that codes for the polypeptide is we are here also asked to highlight the dna sequences.
01:25
So the polypeptide here formed is atg, tac, taa and this taa.
01:42
Now the second question here asked us during transcription which strand of the dna is a template? which strand of the dna is template and in which direction the mrna is transcribed? in which direction the mrna is transcribed? so the dna template is seen in the bottom strand bottom strand and the direction of mrna transcription is left to right.
02:29
So in this question we are given some choices of which the correct answer is option b which says that bottom strand and left to right.
02:50
Now third question here asked is what is the transcribed mrna sequence? transcribed mrna sequence.
03:03
So our polypeptide was we know that the bottom strand is template strand.
03:16
So the top strand will be top strand is the mrna strand.
03:26
So the top strand is as follows that is tacatgattattcacggaatttctagcatcta.
04:02
So this is the sequence...
