Progesterone is a steroid hormone (also described as a ligand) that prepares the body
for pregnancy. It binds to the progesterone receptor (PR) protein in the cytoplasm of
various cells.
Ligand bound PR acts as a transcriptional activator, binds to the DNA in the
promoter region of several genes and leads to transcriptional activation of these
genes.
Which of the following statements must be true for the PR protein?
O Ligand binding to the PR results in a conformational change in the primary
structure of the protein
The domain/region of the PR protein that interacts with the DNA, has basic
amino acids
Ligand binding to the PR results in a conformational change in the tertiary
structure of the protein
The domain/region of the PR protein that interacts with the DNA, has acidic
amino acids
Describe two different types of pre-transcriptional control of gene expression? Give an example of each type.
The first product of genome expression is transcriptome but what happens if the RNA of the genes are not activated at a certain time?

Explain what type of DNA sequence would be altered.arrow_forwardWhich of the following is NOT a reason cells regulate gene expression at a level other than the transcriptional level? Some proteins are only required in part of the cell and transcriptional control will only regulate the mRNA/protein throughout the cell. The core promoter for many genes is the same, so these genes will always be transcribed in the same cells. Differential gene expression in different cell types requires regulation of gene expression at levels other than transcription. Transcription and translation are realtively slow processes, so cells need to regulate gene expression post-transcriptionally if they require a fast change in expression of a gene. Not all cells are transcriptionally active (meaning they do not transcribe any genes), so these cells need to regulate gene expression post-transcriptionally.arrow_forward
