AP Biology Unit 6 Review

Front

What is a bacteriophage?

Back

A bacteriophage is a virus that specifically infects bacterial cells.

Front

What is an inducer in molecular biology?

Back

An inducer is a small molecule that binds to a repressor protein, making it inactive and allowing gene expression.

Front

Define capsid.

Back

A capsid is the protein coat that protects a virus and encases its genetic material.

Front

How do muscle cells differ from nerve cells?

Back

Muscle cells and nerve cells differ mainly because they express different genes.

Front

In which type of organisms are operons found?

Back

Operons are found in prokaryotes.

Front

What is the role of a corepressor?

Back

A corepressor is a molecule that binds to a repressor protein and enhances its ability to inhibit gene expression.

Front

What is the function of a promoter in gene expression?

Back

A promoter is a DNA sequence that initiates transcription of a particular gene.

Front

What is the difference between prokaryotic and eukaryotic cells regarding gene regulation?

Back

Prokaryotic cells often use operons for gene regulation, while eukaryotic cells use more complex regulatory mechanisms.

Front

What is the significance of ribosomes in cells?

Back

Ribosomes are the cellular structures where protein synthesis occurs.

Front

What is a plasmid?

Back

A plasmid is a small, circular piece of DNA found in bacteria that can replicate independently of chromosomal DNA.
