In a lysogenic cycle, the phage genome also enters the cell through attachment and. A prime example of a phage with this type of life cycle is the lambda phage. During the lysogenic cycle, instead of killing the host, the phage genome integrates into the bacterial chromosome and becomes part of the host..These drugs, including the reverse transcriptase inhibitor AZT, inhibit HIV replication by reducing the activity of the enzyme without affecting the host 's metabolism. This approach has led to the development of a variety of drugs used to treat HIV and has been effective at reducing the number of infectious virions copies of .Some viruses have a very narrow host range, meaning that they can only infect one or a small number of cell types, while others have broad host ranges, meaning that they In others, such as retroviruses and reoviruses, the first stages of the viral replication cycle transcription, replication actually occur inside the capsid..This type of viral reproduction ised a lytic LIT ihk cycle. The steps of a lytic cycle for a bacteriophage are il.rated in Figure 7.4. Lysogenic Cycle Some viruses, such as herpes and HIV, enter the host cell but remain hidden for years. Even though the viral nucleic acid becomes part of the host cell 's chromosome, it does .
A virus is a small infectioust that replicates only inside the living cells of other organisms. Viruses can infect all types of life forms, from animals and .Glycolytic control of vacuolar-type ATPase activity: A mechanism to regulate influenza viral infection.RIG-1 and MDA-5 signaling pathways contribute to IFN- production and viral replication in porcine circovirus virus type 2-infected PK-15 cells in vitro.Comparison of viral and bacterial infection; Characteristic Viral infection Bacterial infection; Typical symptoms: In general, viral infections are systemic..

As discussed in lecture 1, there is a period between infection of a cell and the appearance of new infectious virus that is known as the latent period. During this time, several different stages in the virus life cycle are occurring..
Thus, a virus cannot function or reproduce outside a cell, thereby being totally dependent on a host cell in order to survive. Most viruses are species specific, and related viruses typi.y only infect a narrow range of plants, animals, bacteria, or fungi..

Transduction occurs when a bacteriophage transfers bacterial DNA from one bacterium to another during sequential infections. There are two types of transduction: generalized and specialized transduction. During the lytic cycle of viral replication, the virus hijacks the host cell, degrades the host chromosome, and makes more viral genomes..
