Answer 5

Promoter- Start where TF and RNA binds to it
Enchancer- Acts as a switch
Introns-Removed during splicing
Exons-Kept to form m RNA

Question 6

Answer 6

Initiation-Transcription factors are binding to promoters
Elongation-Adds protective cap
Termination-Sequence is cut and poly a tail is added

Answer 7

Edit out introns

Question 8
