Explain why each of these is important in transcription in prokaryotes and/or eukaryotes.
5’ cap
Shine Delgarno sequence
f-met tRNA
A site
Peptidyl transferase
Cap - protects mRNA from degradation by cytoplasmic exonucleases, provides stability to it, helps mRNA to participate in translation
Shine Dalgarno sequence - sequence on mRNA whete ribosome binds so, that it can scan mRNA for start codon
f-met-tRNA - initiator tRNA carrying formylated methionine in prokaryotes
A site - amino acyl site on ribosome where tRNA carrying a new amino acid binds so that the amino acid can be added to the peptide chain
Peptidyl transferase - enzyme responsible for the formation of peptide bond between amino acids in the peptide chain
