What is lysogenic conversion?
Lysogenic conversion occurs when a bacteriophage integrates its DNA into the host bacterium's genome during the lysogenic cycle. This can lead to the insertion of new genetic material that may alter the phenotype of the host bacterium, such as providing new traits or making the bacterium pathogenic.
What is lysogeny?
Lysogeny is when a virus incorporates its genetic material into its hostâ??s genome. This allows the virus to remain dormant until it enters the lytic stage, during which the virus reproduces.
What does a bacterium discard when a virus enters?
When a virus enters a bacterium, the bacterium may discard its own DNA and start producing viral components instead. The viral components take over the bacterium's cellular machinery to replicate themselves.
What happens when a bacteriophage infects a bacteria cell?
When a bacteriophage infects a bacteria it enters either the lyctic or lysogenic cycle. the lyctic is the stages of: injection, reproduction, host destruction. The lysogenic cycle is when the virus' RNA mixes with the host cell's.
What three cell parts do all cells have in common?
All cells have three common features: a cell membrane (plasma membrane) that encloses the cell and controls what enters and exits, cytoplasm where cellular activities occur, and DNA that serves as the genetic material and contains instructions for cell function.

What is the portion of the virus that actually enters the host cell?
its genetic material
What is lysogeny?

When the virus enters a bacteria it leaves behind?
Genetic material, such as DNA or RNA.
What does a bacterium discard when a virus enters?
When a virus enters a bacterium, the bacterium may discard its own DNA and start producing viral components instead. The viral components take over the bacterium's cellular machinery to replicate themselves.
What do B cells produce when an infectious bacterium enters the body?
B cells produce antibodies when an infectious bacterium enters the body. Antibodies are proteins that can recognize and bind to specific molecules on the surface of the bacterium, marking it for destruction by other components of the immune system.
What portion of the virus actually enters a cell is the?
The viral genome typically enters a cell during infection, which contains the genetic material needed for viral replication. The protein coat of the virus, known as the capsid, helps deliver the genetic material into the host cell.
What happens to you when bacteriophage enters your body?
When a bacteriophage enters your body, it infects and replicates within bacteria, not within human cells. Bacteriophages are specific to certain bacterial strains and are harmless to humans. The immune system can detect and eliminate bacteriophages as it would with any foreign substance.
What part of a virus does not enter the host?
Generally, the protein coat that surrounds the viral genetic material and any reverse trascriptase enzymes. This capsid stays outside the cell attacked while the genetic material and whatever else is needed is injected into the cell or the capsid merges with the cell membrane and the vital viral material enters the cell.
When a T2 bacteriophage infects an E. coli cell what part of the phage enters the bacterial cytoplasm?
the whole phage
Why was Alfred Hershey and Martha Chase's experiment so important?
Hershey and Chase's experiment using bacteriophages proved that DNA, not protein, is the genetic material in cells. This discovery was a key milestone in understanding how genetic information is passed from one generation to the next. It laid the foundation for the field of molecular biology.
What causes Actinomycosis?
usually caused by the bacterium Actinomyces israelii. This bacterium is normally present in the mouth but can cause disease if it enters tissues following an injury. Actinomyces israelii is an anaerobic bacterium
