Mutations In Nature Evolution Of Man
1,562 words... iru's is replicated millions of times over, the cell bursts and the new viruses are released to continue the cycle. The body's natural defense against such cell invasion is to release certain proteins, called antigens, which "plug up" the receptor sites on healthy cells. This causes the foreign virus to not have a docking point on the cell. This process, however, is slow and not effective against a new viral attack. Genetic engineering is improving the body's defenses by creating pure antige...

Mutations In Nature Evolution Of Man
1,542 words... A virus invades a host cell by piercing it at a site called a "receptor. Upon attachment, the virus injects its DNA into the cell, coding it to reproduce more of the virus. After the virus is replicated millions of times over, the cell bursts and the new viruses are released to continue the cycle. The body's natural defense against such cell invasion is to release certain proteins, called antigens, which "plug up" the receptor sites on healthy cells.

Biology Lab Report Genetic Exchange In Prokaryotes
679 wordsThis lab deals with the process of genetic exchange in prokaryotes. There are three main mechanisms of genetic exchange which include transformation, transduction, and conjugation. In transformation, DNA is released from cells in the surrounding environment which is then incorporated into the recipient cells DNA. In transduction, DNA is transferred through a virus to the recipient. In conjugation, genetic exchange occurs through direct contact with another cell and the plasmid is transferred fro...
