$(b)$ and $(d)$

Vedclass · Answer

(B) For an $m-RNA$ to be completely translated,it must contain a start codon $(AUG)$ to initiate translation and a stop codon ($UAA, UAG,$ or $UGA$) to terminate it,with the sequence between them being in-frame.$1$. Option $(a)$: $5'-AUG\ UGA\ UUA\ AAG\ AAA-3'$. Here,$UGA$ is a stop codon immediately following the start codon $AUG$. This will result in a very short peptide or no translation,as the stop codon is encountered too early.$2$. Option $(b)$: $5'-AUG\ AUA\ UUG\ CCC\ UGA-3'$. This sequence starts with $AUG$ (start codon) and ends with $UGA$ (stop codon). The codons in between $(AUA, UUG, CCC)$ are sense codons. Thus,it can be translated.$3$. Option $(c)$: $5'-AGU\ UCC\ AGA\ CUC\ UAA-3'$. This sequence lacks a start codon $(AUG)$. Therefore,translation cannot be initiated.$4$. Option $(d)$: $5'-AUG\ UAC\ AGU\ AAC\ UAG-3'$. This sequence starts with $AUG$ (start codon) and ends with $UAG$ (stop codon). The codons in between $(UAC, AGU, AAC)$ are sense codons. Thus,it can be translated.Therefore,sequences $(b)$ and $(d)$ can be completely translated.

Which of the following $m-RNA$ sequences can be completely translated into a polypeptide chain?
$(a)\ 5'-AUG\ UGA\ UUA\ AAG\ AAA-3'$
$(b)\ 5'-AUG\ AUA\ UUG\ CCC\ UGA-3'$
$(c)\ 5'-AGU\ UCC\ AGA\ CUC\ UAA-3'$
$(d)\ 5'-AUG\ UAC\ AGU\ AAC\ UAG-3'$
