Transcription in Eukaryotic and Prokaryotic Cells
Transcription In Eukaryotic Cells
1 Occurs in the nucleus
2 DNA is wounded around histones to form nucleosomes and packaged as chromatin.
mRNA modifies through splicing, capping, and poly A tail.
Same
1 Enzymes are homologous.
2 DNA and RNA
3 Chemical synthesis called transcription.
Transcription In Prokaryotic Cells
1 Occurs in the cytoplasma.
2 Not usually modified
3 DNA is much more accessible to RNA polymerase.
