Practice: Gene Mechanisms
You are doing an experiment to determine the mechanism of gene
expression of a bacterial operon responsible for the utilization of glycerol. You know Abc1 is the regulator. You have two strains of the bacteria: one has the normal Abc1 regulator (+abc1), and the other does not (-abc1). You obtain the following results when growing the two strains with and without glycerol:
Describe the mechanism of regulation.
Write a point form essay outline for the following prompt:
The central dogma of molecular biology is that DNA is transcribed to RNA, which is translated into protein. As such, when we think of DNA, we often picture transcriptionally active euchromatin. However, approx. 10% of interphase DNA in eukaryotes is organized as transcriptionally inactive heterochromatin. Explain the importance of heterochromatin.
