Answer
The purpose of Step A in the process is 'To copy the DNA of a gene sequence onto a strand of mRNA'.
Explanation
## Step 1The question is describing the process of protein production, also known as Protein Synthesis. This process consists of two main stages: Transcription and Translation.## Step 2Step A in the question refers to the first stage of protein synthesis, which is Transcription. During transcription, a DNA sequence is copied onto a strand of mRNA (messenger RNA).## Step 3The descriptions provided by the question are discussing various functions in protein production. These include:- Correcting mutations in the DNA sequence, which is done by DNA repair enzymes but is not directly involved in protein production.- Creating an mRNA transcript, which is the process of transcription.- Assisting in the folding of a protein, which happens after translation.- Producing an exact copy of the DNA molecules, which is the process of DNA replication and occurs before transcription but is not directly involved in protein synthesis.
