CELLS alive! Library: Contents of Volume 6

DNA: Homologous recombination.

6.1 DNA: Homologous recombination.

Two double helices exchange homologous regions, usually so that a non-homologous region farther down can be inserted. This method can be used for insertion of viral DNA into a host cell's genome.

HIV Infection Cycle

6.2 HIV Infection Cycle

Approach, contact, capsid entry, reverse transcription, through budding of new HIV particles from the host surface.

Lymphocyte

6.3 Lymphocyte.

Shows the ruffling activity of the cell membrane, the nucleus and cell granules.

Bacterial motility animation

6.4 Bacterial motility.

Bacteria move by the use of flagellae that give the bacteria a rotary, darting motion as shown in this animation.

Antibodies and bacteria

6.5 Antibodies and bacteria.

Illustrates the attachment of antibodies onto bacteria. Antibodies help "butter" them up for white blood cells to eat.

Viral infection and release

6.6 Viral infection and release.

A generic virus approaches a cell, enters, and the viral genome enters the host nucleus. Multiple copies of the virus are produced and burst from the infected cell.

Viral antigens

6.7 Viral antigens.

Rotating generic virus with a variety of antigen surface structures.

Neurotransmitters and drugs

6.8 Neurotransmitters and drugs.

Illustrates normal activity as well as the effect of various drug classes on neurotransmitter activity and reuptake (e.g. selective serotonin reuptake inhibitors or SSRIs).

Mitosis

6.9 Mitosis

Shows all stages from undivided mother cell through prophase, anaphase, metaphase, telophase, and cytokinesis to form two identical daughter cells.

Antibiotic Resistance

6.10 Antibiotic Resistance

When a population of bacteria is subjected to an antibiotic, many bacteria are killed, but a few may have the ability to evade death. If so, this ability can be passed to later generations. This sequence illustrates the phenomenon of antibiotic resistance - those bacteria that are not killed by a first wave of antibiotic continue dividing and are unaffected by later doses of the drug.
