Protein synthesis or translation

Question 1

mRNA

Answer 1

ribosome binding site near the 5’ end allows ribosome to bind at correct place. codons determine the primary sequence of polypeptide and signal begin and end of translation. start codon is AUG

Question 2

tRNA

Answer 2

before synthesis tRNA must be charged. correct aa is added at 3’ end of tRNA

Question 3

fn of 30S subunit that includes 16S rRNA

Answer 3

helps align mRNA in correct position for initiation or translation

Question 4

fn of 50s subunit that includes 23S rRNA

Answer 4

a peptidyl transferase that catalyzes breakage and formation of peptide bonds

Question 5

E P and A site of ribosomes fn

Answer 5

stablaize the H bonding of tRNA to mRNA

Question 6

what is translocation

Answer 6

when ribosomes move one codon at a time 5’–> 3’ during protein synthesis
