T4r phage
Escherichia virus T4 is a species of bacteriophages that infect Escherichia coli bacteria. It is a double-stranded DNA virus in the subfamily Tevenvirinae from the family Myoviridae. T4 is capable of undergoing only a lytic lifecycle and not the lysogenic lifecycle. The species was formerly named T-even … See more Dating back to the 1940s and continuing today, T-even phages are considered the best studied model organisms. Model organisms are usually required to be simple with as few as five genes. Yet, T-even phages are in … See more T4 is a relatively large virus, at approximately 90 nm wide and 200 nm long (most viruses range from 25 to 200 nm in length). The DNA genome is held in an icosahedral head, also known as a capsid. The T4's tail is hollow so that it can pass its See more Virus T4 genome is synthesized within the host cell using rolling circle replication. The time it takes for DNA replication in a living cell was measured as the rate of virus T4 DNA … See more Multiplicity reactivation (MR) is the process by which two or more virus genomes, each containing inactivating genome damage, can interact within an infected cell to form … See more The T4 virus's double-stranded DNA genome is about 169 kbp long and encodes 289 proteins. The T4 genome is terminally redundant. Upon … See more The T4 virus initiates an Escherichia coli infection by binding OmpC porin proteins and lipopolysaccharide (LPS) on the surface of E. coli cells with its long tail fibers (LTF). A recognition signal is sent through the LTFs to the baseplate. This unravels the short … See more The final step in viral reproduction and multiplication is determined by the release of virions from the host cell. The release of the virions occurs … See more WebDiagram/draw out how you will prepare your serial dilution for the T4r phage (showing amount transferred from one tube to the next tube, amount of broth, dilution at each step, final dilutions).
