Question

Discuss in detail the similarities and differences between prokaryotic and eukaryotic gene structure and their transcription

Answer 1

Answer.

Prokaryotes	eukaryotes
There is no exon in gene Transcription occurs in cytosol mRNA is polycistronic There are three promoter region in prokaryotes i.e -10, -35 and around 100 bp upstream Only have one RNA polymerase. Have only sigma factor as initiator It doesn't have 5' capping and polymerase A tail Transcription and translation occurs simultaneously.	exon are presents. Transcription occurs in nucleus mRNA is monocistronic There are Many promoter region TATA box, initiator elements, downstream core promoter element, CAAT box, and the GC box. There are three type of RNA polymerase. Have many initiator factor. It does have 5' capping and polymerase A tail. Transcription and translation doesn't continue simultaneously
