Chapter 11 Test - Gene Expression

the activation, or "turning on" of a gene that results in transcription and the production of mRNA

• gene expression

• regulator gene

• transcription factor

• cell differentiation

the complete genetic material contained in an individual

• structural gene

• genome

• regulator gene

• homeotic gene

a gene that codes for a product, such as an enzyme, protein, or RNA, rather than serving as a regulator

• genome

• regulator gene

• structural gene

• homeotic gene

NGSS.HS-LS1-1

a short sequence of viral or bacterial DNA to which a repressor binds to prevent transcription (mRNA synthesis) of the adjacent gene in an operon

• operon

• lac operon

• inducer

• operator

a unit of gene regulation and transcription in bacterial DNA that consists of a promoter, an operator, and one or more structural genes

• operon

• lac operon

• euchromatin

• enhancer

a gene system whose operator gene and three structural genes control lactose metabolism in E.coli

• operon

• lac operon

• euchromatin

• homeobox

NGSS.HS-LS3-2

a regulatory protein that binds to an operator and blocks transcription of the genes of an operon

• transcription factor

• homeobox

• repressor protein

• gene expression

a genetic unit that regulates or suppresses the activity of one or more structural genes

• structural gene

• homeotic gene

• genome

• regulator gene

a substance that combines with and inactivates a repressor which allows the transcription of a gene

• inducer

• enchancer

• operator

• metastasis

a region of DNA that is uncoiled and undergoing active transcription into RNA

• genome

• euchromatin

• lac operon

• pre-mRNA
