A bacteriophage is a type of virus that infects a bacterium. Viruses are typically considered nonliving, while a bacterium is a living organism. A bacterium can reproduce by itself, while a virus needs a host in order to replicate. A bacteriophage is much smaller and the term means bacteria eater.
injects its genetic material into the bacterium, taking over the bacterium's cellular machinery to replicate itself. Once the replication process is complete, the bacteriophage releases new viral particles, causing the bacterium to burst open and die.
DNA is the genetic material. However, Hershey-Chase also stated that some little sulfur containing material also entered the bacterial cell. Looking at these two conclusions, Hershey-Chase could not reach a definite conclusion as to whether DNA or Protein contains the genetic material. The conclusion came from Watson-Crick who stated that the sulfur containing material could have entered the cell due to the fact that DNA replication and subsequently translation of the mRNA leads to the synthesis of sulfur containing protein which were found in the bacterial cell.
This transfer of genetic material from one bacterium to another is known as bacterial conjugation. It involves the transfer of plasmids or other mobile genetic elements between bacteria. This can result in increased genetic diversity and potentially introduce new genes, such as antibiotic resistance genes, into the recipient bacterium.
The plural of bacterium is bacteria. The plural possessive is bacteria's.(e.g. The bacteria's differing metabolisms make some more susceptible to the drugs.)
1. Size - T4 is among the largest phages; it is approximately 200 nm long and 80-100 nm wide. Other phages are smaller. Most phages range in size from 24-200 nm in length.2. Head or Capsid - All phages contain a head structure which can vary in size and shape. Some are icosahedral (20 sides) others are filamentous. The head or capsid is composed of many copies of one or more different proteins. Inside the head is found the nucleic acid. The head acts as the protective covering for the nucleic acid.3. Tail - Many but not all phages have tails attached to the phage head. The tail is a hollow tube through which the nucleic acid passes during infection. The size of the tail can vary and some phages do not even have a tail structure. In the more complex phages like T4 the tail is surrounded by a contractile sheath which contracts during infection of the bacterium. At the end of the tail the more complex phages like T4 have a base plate and one or more tail fibers attached to it. The base plate and tail fibers are involved in the binding of the phage to the bacterial cell. Not all phages have base plates and tail fibers. In these instances other structures are involved in binding of the phage particle to the bacterium.
