Molecular Genetics of Prokaryotes Problem Set

Problem 2: Features of eukaryotic mRNAs

Help to answer the question

Which of the following is NOT a feature of eukaryotic gene expression?

Tutorial

The primary distinctions between Prokaryotic vs Eukaryotic Gene Expression are as follows:
A. Eukaryotes are multi-cellular. Gene expression can be development and tissue specific.
B. There are multiple copies for many eukaryotic genes, and a large amount of non-essential DNA.
C. Eukaryotic genes are primarily in the nucleus. mRNAs must cross the nuclear membrane before they are translated in cytoplasm.
D. Many eukaryotic genes are interrupted by non-coding DNA, which is transcribed and then removed by a process known as splicing.
E. Eukaryotic precursor mRNA is extensively modified in the nucleus before translation.
F. Transcription and translation not coupled as in prokaryotes
G. Polycistronic mRNAs rare in eukaryotes.
