Q174 / 180 · JIPMER 2018 · Zoology

Which of the following mRNA can be transcripted as

  • Correct answer
    A
    AUG.UGA.UUU
  • B
    UAA.UAV.UGG
  • C
    UAG.UGA.UUV
  • D
    UGA.UUV.UGG

Solution

Among the given options, only first one can be transcripted because it possesses an initiation codon-AUG which codes for methionine. Rest of the mRNA sequences start with termination codons, i.e. UAA (Ochre), UAG (Amber) and UGA (Opal). Therefore, these cannot be transcripted.

Hence, the correct answer is option: 'A'.
