Question

Put the following steps of protein synthesis in order:

1. Transfer RNA picks up individual amino acids and carries them to the ribosome.

2. An mRNA copy leaves the nucleus and goes to the ribosome.
3. A protein is made.

4. A single strand of DNA is copied to make mRNA.

a
4, 3, 2, 1

b
3, 4, 2, 1
c
1, 2, 3, 4
d
4, 2, 1, 3

Answer 1

The correct order of the steps of protein synthesis is:

4. A single strand of DNA is copied to make mRNA.
2. An mRNA copy leaves the nucleus and goes to the ribosome.
1. Transfer RNA picks up individual amino acids and carries them to the ribosome.
3. A protein is made.

So the answer is:

**d: 4, 2, 1, 3**
