Question
Which of the following lists the correct 5’ to 3’ order of genomic elements of a typical protein coding gene?
promoter, UTR, start codon, polyA signal sequence
promoter, polyA signal sequence, start codon, UTR
start codon, promoter, polyA signal sequence, UTR
UTR, start codon, promoter, polyA signal sequence
A.promoter, UTR, start codon, polyA signal sequence
B.promoter, polyA signal sequence, start codon, UTR
C.start codon, promoter, polyA signal sequence, UTR
D.UTR, start codon, promoter, polyA signal sequence
Explanation / Answer
The correct answer is:
promoter, UTR, start codon, polyA signal sequence
Reason: The sequence from 5' to 3' will be :
5' promoter , cap ,5'UTR , start , coding sequence , stop ,3'UTR , poly A tail 3'
From above sequence we have to choose as per the options given and the best option that fits is option A.
