A)
Promoters Control elements Downstream Distal or proximal
B)
Promoters Control elements Upstream Distal or proximal
C)
Promoters Control elements Distal or proximal Downstream
D)
Promoters Control elements Distal or proximal Upstream
Correct Answer: B
Solution :
The promoter is made up of a basal promoter which is usually located within 40 base pairs from the transcription start site and an upstream promoter (proximal control element) which may be located as far as 200 base pairs from the transcription start site. Control elements can be divided into two kinds, depending on the distance from the basal promoters, proximal control elements and distal control elements. Enhancers and silencers are distal control elements.You need to login to perform this action.
