Question

In humans, about 70% of promoters located near the transcription start site of a gene (proximal promoters) contain a ___ ________

Answer 1

In humans, about 70% of proximal promoters contain a TATA box, a specific consensus sequence found within the core promoter region. The TATA box is the binding site for a protein complex called TFIID, which helps initiate gene transcription.

Step-by-step explanation:

In humans, about 70% of proximal promoters, which are located near the transcription start site of a gene, contain a TATA box. The TATA box is a specific consensus sequence (5'-TATAAA-3') that is found within the core promoter region. It is the binding site for a protein complex called TFIID, which recruits other transcription factors and helps to initiate the transcription of genes.
