Question

Observe the figure of translation and translocation,

Translation and Translocation

i. Which is the initiation codon? Where is it present?

ii. What are the types of RNA present inside the ribosome? Which triplet codon is present on it?

iii. Which genetic code is present on mRNA that is leaving the nucleus? What must be the sequence on the DNA to have such code on mRNA?

Answer 1

i. AUG is the initiation codon, which is present on the mRNA.

ii. There are two molecules of tRNA present inside the ribosome. The triplet codons present on them are UAC and AAG respectively.

iii. The mRNA that leaves the nucleus has genetic code: A U G U U C A A A 

The genetic code on DNA therefore should be as follows: T A C A A G T T T
