Which one of the following steps in elongation is directly dependent on ATP or GTP hydrolysis? Peptide bond formation Movement of the ribosome 3 bases toward the 3’ end of the mRNA Loss of the sigma subunit Binding of initiator tRNA to appropriate AUG codon Translation termination

Movement of the ribosome, 3 bases toward the 3’ end of the mRNA

Explanation:

Movement of the ribosome, 3 bases toward the 3’ end of the mRNA - This process can also be referred to as translator in the ríbosome.

This translocation process requires GTP hydrolysis.

Translocation occurs by the action of the enzyme elongation factor which uses the energy resulting from GTP hydrolysis to move to the A site on the small subunit forcing the tRNA and the mRNA to move a distance of one codon ( 3 bases) through the ribosome.

desert perennials often survive by remaining dormant during dry periods of the year, then springing to life when water becomes available. most annual desert plants germinate only after heavy seasonal rain, then complete their reproductive cycle very quickly.
