Question 11 (Total for Question 11: 5 marks)

What type of promoter element in eukaryotes is most directly involved in transcript initiation? (1 mark)

What are the proteins that interact with these promoter elements? (1 mark)

What type of promoter element is most directly involved in the control of gene expression due to variable conditions (e.g. environmental stresses, hormonal signals, nutritional state)? (1 mark)

How do the proteins that bind to these elements influence gene expression? (1 mark)

Draw and label a diagram to illustrate your answer. (1 mark)

Explanation / Answer

promoter element in eukaryotes which are directly involved in transcription initiation are DNA sequences.in many eukaryotes TATA box is a promoter.upstream elements are used. promoter which contain DNA sequence interact with proteins. proteins bind at -35 and -10 region which are interactions regions.this promoter binding process influence the gene expression.
