Unit 1 Study

Front

Define gene expression.

Back

The process by which information from a gene is used to synthesize a functional gene product, usually a protein.

Front

Explain why gene expression is important in the life of an organism.

Back

It enables the organism to grow, develop, and respond to its environment by producing necessary proteins.

Front

What does the presence of a repressor protein indicate in gene expression?

Back

The gene is turned off and not being transcribed.

Front

What is the significance of cell differentiation in gene expression?

Back

It allows cells to become specialized for specific functions.

Front

What is the role of proteins in gene expression?

Back

Proteins act as enzymes and structural components, and they regulate gene expression.

Front

What is a gene?

Back

A segment of DNA that contains the instructions for making a specific protein.

Front

What is transcription in the context of gene expression?

Back

The process of copying a segment of DNA into RNA.

Front

What is translation in the context of gene expression?

Back

The process of synthesizing a protein from the mRNA template.

Front

What is the function of messenger RNA (mRNA)?

Back

To carry the genetic information from DNA to the ribosome for protein synthesis.

Front

What is the role of ribosomes in gene expression?

Back

Ribosomes are the sites where proteins are synthesized from mRNA.
