Lecture 23 Bacterial Gene Regulation

Flashcards for reviewing bacterial gene regulation lecture.

Gene Regulation

Controlled as to whether they are expressed or not, either on, off, high, or low level

Gene Expression

Whether genes are transcribed and translated to make their protein

Constitutively Expressed Genes

Genes that need to be expressed all the time

Tryptophan

An amino acid required to make proteins that bacterial cells can synthesize.

Biosynthetic Pathway

Describes the steps taken from an original molecule to the final product and can involve multiple enzymes

Rate Limiting Step

The first enzyme in a biosynthetic pathway which is subject to feedback inhibition.

Feedback Inhibition

Tryptophan is able to bind the first enzyme and prevent it from doing its job

Clustered Genes

Genes that are physically connected to each other on a part of the DNA in the bacterial chromosome
