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's DNA and can remain dormant for a long period without causing immediate harm.

Front

What is a lytic infection?

Back

A lytic infection is a type of viral infection where the virus takes over the host cell's machinery to produce new viruses, leading to the destruction of the host cell.

Front

What is osmosis?

Back

Osmosis is the movement of water molecules from an area of high concentration to an area of low concentration across a semipermeable membrane.

Front

What is the difference between prokaryotic and eukaryotic cells?

Back

Prokaryotic cells do not have a nucleus, while eukaryotic cells do have a nucleus that contains their genetic material.

Front

What is active transport?

Back

Active transport is the movement of molecules across a cell membrane from a region of lower concentration to a region of higher concentration, requiring energy.

Front

What is diffusion?

Back

Diffusion is the process by which molecules spread from an area of high concentration to an area of low concentration without the need for energy.

Front

What role do ribosomes play in a cell?

Back

Ribosomes are the cellular structures responsible for synthesizing proteins by translating messenger RNA (mRNA) into amino acid sequences.

Front

What is the function of the cell membrane?

Back

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

Front

What is the purpose of cellular respiration?

Back

Cellular respiration is the process by which cells convert glucose and oxygen into energy (ATP), carbon dioxide, and water.

Front

What is a virus?

Back

A virus is a microscopic infectious agent that can only replicate inside the living cells of an organism.
