14.3 - 6 GENE REGULATION & EXPRESSION

Question 1

Operon

Answer 1

In prokaryotes, a group of adjacent genes that shares a common operator and promoter and are transcribed into a single mRNA.

Question 2

Operator

Answer 2

Short DNA region, adjacent to the promoter of a prokaryote operon, that binds pressure proteins, responsible for controlling the rate of transcription of the operon.

Question 3

Differentation

Answer 3

Process in which cells become specialized structure and function.

Question 4

Homeotic gene

Answer 4

A class regulatory gene, the identity of body parts, and in an animal embryo. Mutation in these genes can transform one body part into another.

Question 5

Homeobox gene

Answer 5

Genes that code for transcription factors that activate other genes that are important in cell development and differentiation.

Question 6

Hox gene

Answer 6

A group of homeotic jeans cluster together that determine the identity of body parts in animals. All hox genes that contain the whole box DNA sequence.
