T4 cells, also known as CD4 or helper T cells, protect the immune system in the body from infection. These cells release cytokines into the blood stream as a defense against antigens from viruses.

At what point in the reproductive cycle of the T4 bacteriophage is host cell infection irreversible?

Once the T4 bacteriophage injects its genetic material into the host cell, infection becomes irreversible. This usually occurs as soon as the phage's tail fibers attach and the genome is injected, initiating the takeover of the host cell machinery for viral replication.


How cell movement occurs?

Movement within the cell occurs by microtubules, which act like railroads to help transportation of vessicles and organelles. Movement of the cell itself occurs by either the cilia or the flagella.


Cellular respiration occurs within the of a cell?

The mitochondria.


Is T4 bacteriophage a DNA or RNA virus?

T4 bacteriophage is a DNA virus. It infects bacteria by injecting its DNA into the host cell and hijacking the cell's machinery to replicate its genetic material.


Is a growth disorder of cells that occurs when cell divide uncontrollably within the body?

cancer


Which events occurs in the lytic cycle of bacteriophage T4 infection but not in the lysogenic cycle?

In the lytic cycle of bacteriophage T4 infection, the viral DNA takes control of the host cell machinery to replicate and assemble new viruses, leading to cell lysis and release of viral particles. This process does not involve integration of the viral DNA into the host genome, which is a key characteristic of the lysogenic cycle.


In cell cycle where mitosis occurs?

Mitosis occurs during the cell cycle in the M phase. This phase follows the G2 phase and is essential for cell division and reproduction. During mitosis, the cell nucleus divides into two identical daughter nuclei.


What is the shrinkage of cytoplasm within a cell from diffusion is known as?

The shrinkage of cytoplasm within a cell from diffusion is known as crenation. This occurs when water moves out of the cell due to a higher solute concentration outside the cell, leading to the cell shrinking and potentially losing its functionality.


What point in the reproductive cycle of the T4 bacteriophage is host cell infection irreversible?

Once the viral DNA is duplicated in the cell.


Where in the plant cell does photosynthesis occur?

Within Chloroplasts.


Aerobic respiration occurs in which organelle of the cell?

Cellular aerobic respiration occurs within the mitochondria.Cellular respiration occurs in the mitochondria of a cell. Mitochondria are the "cellular power houses" that conduct oxygen and glucose through the cell to the other mitochondria, which use the oxygen and glucose to power the cell. After being used, the oxgen and glucose is transformed into carbon dioxide and water.


Is tryptophanase a exoenzyme?

No, tryptophanase is an endoenzyme, meaning it acts on a substrate within the cell where it is produced rather than outside the cell. It catalyzes the breakdown of tryptophan into indole, pyruvate, and ammonia.
