The Ribosomes

Question

The ribosomes
A)move along the tRNA in a 3'-5' direction.
B)move along the mRNA in a 5'-3' direction.
C)move along the DNA in a 5'-3' direction.
D)provide a platform which brings the amino acids into a favorable position for joining.
E)move along the mRNA in a 5'-3' direction AND provide a platform which brings the amino acids into a favorable position for joining.

Accepted Answer

Ribosomes move along the mRNA in a 5'-3' direction and provide a platform which brings the amino acids into a favorable position for joining. This allows the ribosome to synthesize a polypeptide chain in a linear fashion by joining each amino acid according to the sequence of the mRNA. The tRNA moves along with the ribosome and interacts with the mRNA to ensure the correct placement of each amino acid.
