Which of the following is true about transcription factors?
A
Transcription factors are involved in the translation process.
B
Transcription factors bind to DNA to regulate gene expression.
C
Transcription factors are enzymes that synthesize RNA.
D
Transcription factors are only found in prokaryotic cells.
Verified step by step guidance1
Understand the role of transcription factors: Transcription factors are proteins that help regulate the expression of genes by binding to specific DNA sequences.
Clarify the process of gene expression: Gene expression involves transcription, where DNA is converted into RNA, and translation, where RNA is used to synthesize proteins. Transcription factors are primarily involved in the transcription phase.
Identify the function of transcription factors: They bind to promoter regions or other regulatory sequences on DNA to either enhance or inhibit the transcription of specific genes.
Differentiate transcription factors from enzymes: Transcription factors are not enzymes that synthesize RNA; rather, they facilitate the binding of RNA polymerase to DNA, which is the enzyme responsible for RNA synthesis.
Recognize the presence of transcription factors: They are found in both eukaryotic and prokaryotic cells, although their complexity and mechanisms can vary between these types of organisms.
