Question

During translation, which step on occurs immediately after the ribosome reads an mRNA codon?

A. A tRNA molecule binds to the ribosome.

B. The new strand of mRNA leaves the nucleus.

C. The ribosome attaches to the strand of mRNA.

D. The finished polypeptide is released.

Answer 1

A. A tRNA molecule binds to the ribosome.

Step-by-step explanation:

As the ribosome "reads" the mRNA, tRNAs bind and add on to the growing polypeptide by adding a single amino acid for each codon (3 bases).
