Which are characteristics of regulatory transcription factors? (select all that apply)

a. Act at cis-acting elements

b. Activity modulated by protein-protein interactions

c. Bind to promoter sequence

d. Activity sometimes modulated by small effector molecules

e. Regulate transcription of specific target genes

f. Can act to repress or activate transcription

g. Activity modulated by covalent modifications

Expert Solution

Bind to promoter sequence

Regulate transcription of specific target genes

Can act to repress or activate transcription

Activity modulated by protein-protein interactions

Activity sometimes modulated by small effector molecules

Activity modulated by covalent modifications

Necessary for basal level of transcription

Transcription factor: Proteins that bind to DNA and regulate in the initiation of transcription. These are specialized that control gene expression.A major family of transcription factors are sequence specific DNA binding proteins. Transcription factor recruit and instructs RNA poll II to initiate RNA synthesis at specific genes by recognizing and binding to DNA elements called as promoters.
