Terms #7

Question 1

Gene Regulation

Answer 1

Used to control the timing, location, and amount of gene is expressed

Question 2

Operon

Answer 2

Neighboring genes in a genome and are transcribed together into a single mRNA

Question 3

Operator

Answer 3

Located in operon that is a binding site for repressor

Question 4

Repressor

Answer 4

Protein that prevents expression of one or more genes

Question 5

Corepressor

Answer 5

Regulates gene expression by binding to repressor (times off gene expression)

Question 6

Inducer

Answer 6

Binds to repressor (turns on gene expression)

Question 7

Activator

Answer 7

Protein that increases the production of a gene product

Question 8

Differential gene expression

Answer 8

Different genes are expressed in a cell and give cell a specific purpose

Question 9

Transformation

Answer 9

Foreign material is taken up by a cell

Question 10

Transduction

Answer 10

Virus transfers genetic material from one cell to another

Question 11

Conjugation

Answer 11

Through direct contact, bacterial cell transfers genetic material to another

Question 12

Epigenetic inheritance

Answer 12

Change in gene expression (not DNA themselves) are passed down

Question 13

Control elements

Answer 13

Binding sites for regulatory proteins, allowing for control of rate of gene expression

Question 14

Enhancers

Answer 14

Increases transcription of gene, regulatory to boast gene expression

Question 15

DNA methylation

Answer 15

Chemical modification, alter gene expression, DNA more accessible

Question 16

Histone acetylation

Answer 16

Acetyl added to lysine amino acids on tail of histone proteins, make DNA more accessible
