Question

Ribosomes create, or synthesize, proteins through the use of DNA and RNA. Which of these is a step in protein synthesis? A. The ribosome starts decoding when it attaches to the mRNA. B. The ribosome moves down the mRNA strand from one codon to the next as the tRNA brings each corresponding amino acid. C. When the ribosome reads the last mRNA codon, it signals the end of translation. D. All of these

Answer 1

Answer:

D

Explanation:

These are all steps of translation or protein synthesis

Answer 2

Answer:

all of these

Explanation:

All of these are steps in the general process of protein synthesis:

First, when the mRNA attaches to the ribosome, the ribosome starts decoding. Then, the ribosome moves down the mRNA strand from one codon to the next as the tRNA brings each corresponding amino acid. Finally, when the ribosome reads the last mRNA codon, it signals the end of translation.

This mechanism is virtually the same in all life forms.
