Question

Transcription factors are __________.

Select one:

a. regulatory bases that bind to the promoter

b. none of these

c. regulatory proteins that bind to a promoter site

d. regulatory sequences that bind to a protein

e. regulatory DNA sequences that bind to the promoter site

Answer 1

The correct answer is Option c. Regulatory proteins that bind to a promoter site.

Transcription factors are basically proteins. They are the DNA binding proteins and involved in the gene transcription. They binds to DNA of promoter and controls the gene expression. Transcription factors either converts or transcribes DNA into RNA. They are needed in the transcription of all the protein coding genes.

Option a. Regulatory bases that bind to the promoter is not the right answer because transcription factors are regulatory proteins.

Option b. None of these is not the right answer because the correct answer is there in the options.

Option d. Regulatory sequence that bind to a protein is not the right answer because they are regulatory proteins.

Option e. RegulatoryDNA sequences that bind to the promoter site is not the right answer because transcriptions factors are regulatory proteins that binds to the promoter of DNA.
