Enter the number 1 characteristic is a property or properties of the number 2 if the characteristic listed is a property of enhancers position can be upstream, downstream or within a gene (a)____ may influence the expression of more than one gene (b)___ TATA, CAAT, GC boxes (c)____ always upstream of the gene within 100 bases of the transcription initiation site (d)____ required for basal level transcription (e)____ not required for basal level transcription (f)____responsible for tissue-and time-specific gene expression (g)

Explanation / Answer

In molecular genetics, promoter is described as a DNA region which has property of initiating the transcription process of a specific gene

an enhancer is a DNA sequence which allows binding of certain types of proteins so as to speed up or increase the likeliness of transcription process

a-promoter

b-enhancer

c-promoter

d-enhancer

e-enhancer

f-promoter

g-promoter
