Which of the following refers to the RNA-to-protein step in the expression of genes?Multiple choice question.replicationtranslationtranscription

Breakdown of the Problem

To determine which term refers to the RNA-to-protein step in gene expression, we need to understand the different processes involved in gene expression.

Relevant Concepts

1. Replication: The process by which DNA makes a copy of itself.
2. Transcription: The process of synthesizing RNA from a DNA template.
3. Translation: The process by which ribosomes synthesize proteins using the mRNA template.

Analysis and Detail

In the context of gene expression:

• Replication is not relevant here as it pertains to DNA duplication, not RNA or protein synthesis.
• Transcription converts the DNA sequence into RNA but does not involve protein synthesis.
• Translation is the step where the information in the RNA (specifically messenger RNA, or mRNA) is used to build a protein.

Verify and Summarize

After analyzing the processes:

• Replication = DNA to DNA
• Transcription = DNA to RNA
• Translation = RNA to Protein

Thus, the correct answer to the question is Translation.

Final Answer

Translation refers to the RNA-to-protein step in the expression of genes.
