MCB 2050 Lecture Notes #1 Exam
Questions and Answers | Graded A+
Eukaryotes are multicellular. What does this compartmentalization
achieve? - Compartmentalization allows for complex eukaryotic gene
regulation.
What does complexity achieve? - Multiple levels of gene control.
Therefore, what do...
Otherwise, consider protein-DNA interaction on gene regulation. Is it
different from prokaryotes? - ✔✔No, it is still positively and negatively
regulated, and transcription factors remain the same.
Consider the induction of gene expression. Give examples? -
✔✔Biological factors and Environmental factors. Specifically with
biological factors, steroid and peptide hormones. Heat Shock is an example
of an environmental factor.
How is gene expression regulated by steroid hormone? - ✔✔Steroid
hormone, a lipid-soluble molecule derived from cholesterol, is able to
permeate the cell membrane.
1. The steroid hormone combines with the receptor protein.
2. The hormone/receptor complex binds to hormone response element in
the DNA.
3. Stimulates transcription.
How is gene expression regulated by peptide hormone? - ✔✔Peptide
hormone, a linear chain of amino acid, is unable to permeate the cell
membrane.
1. The peptide hormone attaches to membrane-bound receptor proteins
and activates.
