Question

How does the primary transcript in a prokaryotic cell compare to the functional mrna?

Answer 1

Answer:

The primary transcript is the same size as the functional mRNA

Explanation:

• Genetic information carried by the DNA is used to generate proteins through the process of gene expression. Gene expression involves the process of transcription and translation.
• During transcription information in the DNA is used to generate a primary transcript which in turn forms a messenger RNA.
• The primary transcript from the process of transcription undergoes excision to remove non-coding sequences so as tor form the functional mRNA in eukaryotes. This explains why the primary transcript in eukaryotes is larger than the functional messenger RNA.
• However, in prokaryotes the primary transcript is the same size as the functional RNA.
