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

The Big Idea Over 2500 years ago Aristotle proposed two laws of physics governing motion. One for ‘Earthly bodies’ (objects on Earth) that states objects naturally go in straight lines and one for ‘Heavenly bodies’ (objects in space) that states objects naturally go in circles. This idea held steady for 2‚000 years‚ until Isaac Newton in a triumph of brilliance declared that there is one law of physics that governs motion and he unified “earthly” bodies and “heavenly” bodies with the The Universal

The Zika Virus is slowly spreading across the globe and it’s becoming more and more dangerous. The only real problem about Zika is that it doesn’t have a cure and that many babies end becoming deformed due to the Zika Virus. Zika is spread by the bite of an Aedes Mosquito these mosquitoes are known to carry the deadly virus. Another main problem is how common it is to get bitten by a mosquito and the fact that this disease can be passed to babies is terrifying and it can make babies look completely

“Could the next threat be in your backyard?” The Zika virus is a virus that can take down a whole town. The zika virus is spread rapidly by mosquitoes; history shows the symptoms and treatment are very limited. In 1947 the zika virus started in a forest called Uganda’s zika forest. The scientist did think it would come back‚ but in the summer of 2016 the virus came back. He virus started in Brazil and now spreading to Rio and now is going to Latin America. The invasion in Brazil was started a

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

LETTER OF TRANSMITTAL Chapter one Computer virus COMPUTER VIRUS A computer virus is a computer program that can replicate itself and spread from one computer to another. The term "virus" is also commonly‚ but erroneously‚ used to refer to other types of malware‚ including but not limited to adware and spyware programs that do not have a reproductive ability. Malware includes computer viruses‚ computer worms‚ ransomware‚ Trojan horses‚ keyloggers‚ most rootkits‚ spyware‚ dishonest

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
