alleryStart learning →Eukaryotic mRNAs are usually monogenic. What does that mean?
AEach transcript specifies a single protein
BEach transcript carries a single intron
CEach gene is copied by a single polymerase
DEach protein is built by a single ribosome
Answer & Solution
Correct answer: A. Each transcript specifies a single protein
1. Monogenic describes how many proteins one transcript can specify.
2. A eukaryotic mRNA usually specifies a single protein.
3. Prokaryotic transcription instead often produces polycistronic mRNAs covering more than one gene.
