Question

A diagram of the steps in the production of a protein is shown. What is the correct sequence of steps?
Step B, Step A, Protein
Protein
STAAR
Protein, Step A, Step B
Step A, Step B, Protein
Step A, Protein, Step B

Answer 1

To determine the correct sequence of steps in the production of a protein, we should consider the general process of protein synthesis, which involves:

1. Transcription (Step A): This is the first step where the DNA sequence of a gene is transcribed to produce mRNA (messenger RNA).

2. Translation (Step B): In this step, the mRNA is translated into a polypeptide chain, which then folds into a functional protein.

Using this understanding, this sequence corresponds to:

Step A (Transcription), Step B (Translation), Protein

Thus, the correct sequence of steps should be:

Step A, Step B, Protein

So the answer is:

Step A, Step B, Protein.
