Introduction A bacteriophage is a virus that infects bacteria. A type of bacteriophage is bacteriophage lambda. This specific bacteriophage infects E. Coli. It is composed of protein and double stranded DNA ¡VdsDNA). The DNA of the phage contains around 50‚000 base pairs and codes for 50 proteins. At both ends of the DNA of the phage‚ there are cohesive ends‚ which are composed of 12 nucleotides. Both ends compliment each other‚ which makes the DNA circular once together. This circular DNA

inflammation of both the tonsils and the pharynx (located at the back of the throat). It occurs due to viral or bacterial infections. In rare cases a fungus or parasite can also cause tonsillitis. Other common causes are Adenoviruses‚ Influenza virus‚ Herpes Simplex virus and Enteroviruses. There are 4 types of Tonsillitis. Acute Tonsillitis is an acute inflammation of the tonsillar tissue. Children are mostly affected and this ordinary simple disease can sometime lead to serious complications. Recurrent

1. What is a Virus? A computer virus is a program that can copy itself and infect a computer without the user knowing. Some viruses are made to damage the computer by damaging programs‚ deleting files‚ or reformatting the hard disk. Others are not designed to do any damage‚ but replicate themselves and perhaps make their presence known by displaying text‚ video‚ or audio messages. Even these benign viruses can create problems for the computer. They usually take up computer memory used by other programs

Type A Influenza Virus Essay Influenza: a virus that replicates‚ mutates‚ spreads among species‚ and the cause of the recent H1N1 scare is definitely an apparent danger to humans today. Type A influenza is an RNA virus that ‘reproduces’ through replication. The virus particles are surrounded by hemagglutinin (HA) and neuraminidase (NA) – both are structural glycoproteins attached to the virus’s outside lipid bi-layer. HA serves its function in helping the virus to bind to the sialic acid receptors

The hepatitis C virus (HCV) is a single-strand and positive-sense RNA virus of the Hepacivirus genus in the Flaviviridae family (1). According to the organization of the HCV genome‚ the virus is divided into 7 genotypes and more than 60 subtypes. The seven genotypes of this virus are seen in all over the world. It is known that HCV genotype one and four are hard to treat‚ while genotype 2 and 3 have more comfortable treatment. Thus‚ identification of HCV genotype in infected patients is essential

Lecture 2- overview of the virus 1. The first step- the virus binds to a receptor-->entry and uncoating--> early gene expression-->replication of viral genome-->late gene expression->assembly of viral progeny-->exit 2. Concept 2.1- Virus entry is a multistep process with the ultimate goal of delivering viral genome (payload) into the cells. A. Binding to surface receptors- - a viral receptor is cell surface molecule‚ likely a transmembrane protein - a virus may need multiple receptors
