1 ribosome moves along mRNA at one time, multiple copies of same protein made from single mRNA
more than 1 ribosome moves along mRNA at one time, multiple copies of same protein made
more than 1 ribosome moves along mRNA at one time, making one protein copy
1 ribosome moves along mRNA at one time, making one copy of protein
3. What happens during initiation?
more than 1 ribosome moves along mRNA at one time
complex forms, initiator tRNA charged with methionine + small ribosomal subunit bound to mRNA triggers beginning of translation
presence of stop codon in A site of ribosome, completed protein released
ribosome moves along mRNA in 5'-to-3' direction, polypeptides grow from N terminus, charged tRNA's bring amino acids to the ribosome sequentially
4. What four components does translation require?
ribosomes, tRNA, activating enzymes + mRNA
ribosomes, DNA, activating enzymes + mRNA
cytoplasm, tRNA, activating substrates + mRNA
cytoplasm, DNA, activating substrates + mRNA
5. What happens during termination?
more than 1 ribosome moves along mRNA at one time
presence of stop codon in A site of ribosome, completed protein released
ribosome moves along mRNA in 5'-to-3' direction, polypeptides grow from N terminus, charged tRNA's bring amino acids to the ribosome sequentially, specificity provided by: the anticodon interaction and the accuracy of aminoacyl-tRNA synthetases.
complex forms, initiator tRNA charged with methionine + small ribosomal subunit bound to mRNA triggers beginning of translation
