Basal Factors and Transcription Initiation

What is the role of basal factors in transcription initiation?

Choose one:

1. Position RNA polymerase at the start of a gene
2. Enhance gene expression
3. Initiate translation
4. Regulate mRNA splicing

The role of basal factors in transcription initiation:

The correct answer is: Position RNA polymerase at the start of a gene.

Basal factors play a crucial role in ensuring that transcription initiation occurs efficiently in a cell. These factors help position RNA polymerase at the start of a gene, ensuring that the correct gene is transcribed at the right time. Without basal factors, the transcription process would be less precise and may lead to errors in gene expression.

Basal factors work in conjunction with other transcription factors to form the initiation complex, which is essential for the transcription of genes. By positioning RNA polymerase at the start site of a gene, basal factors play a key role in regulating gene expression and initiating the process of transcription.
