What is a lysogenic infection?

Back

A lysogenic infection is a type of viral infection where the virus integrates its genetic material into the host cell's DNA and can remain dormant for a long period before becoming active.

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, while a lytic virus immediately directs the production of new viruses.

Front

What happens during the S phase of the cell cycle?

Back

DNA replicates during the S phase of interphase.

Front

What do viruses and living cells have in common?

Back

They both store genetic information.

Front

Define phenotype.

Back

Phenotype is the observable physical or biochemical characteristics of an organism, determined by both genetic makeup and environmental influences.

Front

What is the role of mitosis in the cell cycle?

Back

Mitosis is the process by which a cell divides its nucleus and genetic material, resulting in two identical daughter cells.

Front

What is interphase?

Back

Interphase is the phase of the cell cycle where the cell prepares for division, consisting of G1, S, and G2 phases.

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 genetic variation?

Back

Genetic variation refers to the differences in DNA sequences among individuals, which can lead to different traits.
