Nucleic acids and protein synthesis

Question 1

Describe translation

Answer 1

mRNA, attaches to / associates with / AW, ribosome ;
A ribosome reads mRNA
2 two codons, exposed / AW ;
A A and P sites / first and second binding sites, (on ribosome)
3 tRNA, qualified carries an amino acid to ribosomes / each type carries a specific amino acid / first amino acid is
met / tRNA with met / tRNAmet ;
ref. to ribosomes can be implied in mp 3 if mp1 gained
4 anticodon (on tRNA) binds to codon (on mRNA) ; I matches
A complementary / base, pairing between codon and anticodon
A H-bonds form between bases on codon and anticodon
R if anticodon on mRNA
5 START (mRNA) codon / (mRNA) AUG first codon ;
6 second tRNA with its amino acid binds next to first tRNA / (two) amino acids are held in place close to each other by
tRNA binding / AW ;
A ref. to two tRNAs next to each other
7 (after peptide bond formation) first tRNA detaches / ribosome moves along one codon
or
process repeats / elongation occurs, until, STOP codon / polypeptide chain synthesised (and released from ribosome) ;
8 tRNA molecules, reused / leave ribosome to attach to another amino acid ;
