See AnswerQ: Transcription factors such as the glucocorticoid receptor and the CREB protein form
Transcription factors such as the glucocorticoid receptor and the CREB protein form homodimers and activate transcription. Other transcription factors form heterodimers. For example, a transcription f...
See AnswerQ: An enhancer, located upstream from a gene, has the following
An enhancer, located upstream from a gene, has the following sequence: 5′–GTAG–3′ 3′–CATC–5′ This enhancer is orientation-independent. Which of the following sequences also works as an enhancer? A....
See AnswerQ: The DNA-binding domain of each CREB protein subunit recognizes the
The DNA-binding domain of each CREB protein subunit recognizes the sequence 5′–TGACGTCA–3′. Due to random chance, how often would you expect this sequence to occur in the human genome, which contains...
See AnswerQ: The gene that encodes the enzyme called tyrosine hydroxylase is known to
The gene that encodes the enzyme called tyrosine hydroxylase is known to be activated by the CREB protein. Tyrosine hydroxylase is expressed in nerve cells and is involved in the synthesis of catechol...
