Answer #1

Solution:

1. a. 5' to 3', Codons (mRNA are translated in the 5'→3' direction, Codons are composed of three-nucleotides).


2. c. (it is 40S ribosomal subunit bound with the methionyl tRNA and eIFs, which scans the mRNA and identifies the the AUG start codon).

3. a (Primarily a prokaryotic mechanism).

Hope it helps

    Question 9: The genetic code is read in groups of three nucleotides, called codons, in mRNA that specifies for a particular amino acid. tRNA molecules act as the amino acid carriers that by correctly pairing with the codon on mRNA can deliver the correct amino acid to the ribosome during translation. At the tip of each tRNA molecule is a group of three nucleotides called an anticodon and at the other end is where the corresponding amino acid is attached...
