प्रश्न
Given below is a stretch of DNA showing the coding strand of a structural gene of a transcription unit?
5’-ATG ACC GTA TTT TCT GTA GTG CCC GTA CTT CAG GCA TAA-3’
- Write the corresponding template strand and the mRNA strand that will be transcribed, along with its polarity.
- If GUA of the transcribed mRNA is an intron, depict the sequence involved in the formation of mRNA/the mature processed hnRNA strand.
i. In a bacterium
ii. In humans - Upon translation, how many amino acids will the resulting polypeptide have? Justify.

उत्तर
5’-ATG ACC GTA TTT TCT GTA GTG CCC GTA CTT CAG GCA TAA-3’ = CODING
- 3’-TAC TGG CAT AAA AGA CAT CAC GGG CAT GAA GTC CGT ATT-5’ = TEMPLATE
5’-AUG ACC GUA UUU UCU GUA GUG CCC GUA CUU CAG GCA UAA-3’ - i. In a bacterium
5’-AUG ACC GUA UUU UCU GUA GUG CCC GUA CUU CAG GCA UAA-3’
ii. In humans
5’-mGpppAUG ACC UUU UCU GUG CCC CUU CAG GCA UAA - Poly A tail-3’ - 9 amino acids in the polypeptide because UAA is a stop/terminator codon and does not code for any amino acid.
