Q
ways transcription is different in eukaryotes:
A
they have 3 RNA polymerases
RNA polymerases are more complex
RNA polymerases requires transcription factors to recognize promoters
- TATA box (promoter sequence( bound by TATA-binding transcription factors
do not use operons (each gene has its own promoter)
mRNA are poladenylated at the end (3’) of transcript and capped at 5’ end using modified G residues attached using an unusual linkage
mRNAs transcribed/spliced in nucleus, translated in cytoplasm
