Front

What are the two kinds of cells?

Back

Prokaryotes and Eukaryotes.

Front

What is a key difference between Prokaryotes and Eukaryotes?

Back

Eukaryotes have a nucleus.

Front

What is a lysogenic infection?

Back

A type of viral infection where the virus integrates into the host DNA and can remain inactive for a long time.

Front

What is a lytic infection?

Back

A type of viral infection where the virus immediately takes over the host cell to produce new viruses.

Front

How does a lysogenic infection differ from a lytic infection?

Back

A lysogenic virus can remain in the host DNA for a longer period without becoming active.

Front

What is the function of a nucleus in a cell?

Back

The nucleus contains the cell's genetic material and controls its activities.

Front

What are the main components of a prokaryotic cell?

Back

Prokaryotic cells typically have a cell membrane, cytoplasm, ribosomes, and genetic material (DNA) but lack a nucleus.

Front

What is the role of ribosomes in a cell?

Back

Ribosomes are responsible for protein synthesis.

Front

What is the difference between DNA and RNA?

Back

DNA is double-stranded and contains the sugar deoxyribose, while RNA is single-stranded and contains the sugar ribose.

Front

What is the purpose of the cell membrane?

Back

The cell membrane regulates what enters and exits the cell, providing protection and structure.
