Describe briefly what is occurring at each step in the figure
What will be an ideal response?
This figure represents protein synthesis. Step one, the initiator tRNA attaches to a start codon. In step two, the large and small ribosomal subunits join to form a functional ribosome and initiator tRNA fits into P site. In step three, the anticodon of an incoming tRNA pairs with the next mRNA codon at A site. Step four, the amino acid on the tRNA at P site forms a peptide bond with the amino acid at A site. Step five, the tRNA at the P site leaves the ribosome and the ribosome shifts down by one codon. The tRNA previously at the A site is now at the P site. Step six is when protein synthesis stops when the ribosome reaches one of three potential stop codons on the mRNA strand.
