1) Androgens are steroid hormones. This is an example of what type of cellular signaling? Where would you expect the receptor for androgen to be?

2) Describe the relationship between enhancers, silencers, activators, repressors and transcription factors.

3) If a gene is moved experimentally from a DNA region of Euchromatin to heterochromatin its expression would probably increase or decrease? Why?

Solution

Answer1:

Answer 2:

Answer 3: If a gene is moved experimentally from a DNA region of Euchromatin to heterochromatin its expression would decrease. A research study showed that in Drosophila variegated expression and reduced transcription of euchromatic genes is observed when DNA from euchromatin was moved to heterochromatin. Though heterochromatin provides an environment, which is accessible and not closed, but they are not favorable for the expression of euchromatic genes.
