Does transcription or translation occur first?
Understand the Problem
The question is asking about the process of gene expression, specifically whether transcription or translation occurs first in the central dogma of molecular biology. Transcription is the process where a segment of DNA is copied into RNA, while translation is the process where the RNA is used to synthesize proteins.
Answer
Transcription occurs first.
Transcription occurs first, followed by translation.
Answer for screen readers
Transcription occurs first, followed by translation.
More Information
Transcription is the process of synthesizing mRNA from DNA. Once transcription is complete, mRNA is translated to form proteins.
Tips
A common mistake is to confuse the sequence of events in gene expression. Remember, transcription must occur before translation.
