How is the process of transcription different in prokaryotes and eukaryotes?

Answer 1

Some differences between prokaryotic and eukaryotic transcription are...

Prokaryotes: their transcription is highly streamlined (no post-transcriptional processing of RNA), occurs in the cytoplasm of the cell (no nucleus), has initiation factors like sigma factor, and recruits RNA polymerase. Their promoter is located at -10 TATAAT and -35 TTGACAT.

Eukaryotes: more complex than prokaryotic initiation; transcription takes place in the nucleus; RNA is processed (cut, spliced, modified) in the nucleus; exported to the cytoplasm for protein translation; promoter at: -30 TATA (e.g.); transcription factors (TF): numerous; pre-mRNA needs processing before it becomes a functional mature mRNA (unlike in prokaryotes);

Prokaryotes have cytoplasmic transcription, whereas eukaryotic transcription takes place in the nucleus. Prokaryotic transcription is carried out by a single RNA polymerase enzyme, whereas eukaryotic transcription is carried out by three RNA polymerase enzymes. Prokaryotic genes are usually arranged into operons, whereas eukaryotic genes are arranged into individual transcription units with introns and exons. Prokaryotic mRNA is not subjected to significant processing, whereas eukaryotic mRNA is subjected to substantial processing, including capping, splicing, and polyadenylation.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
