Evolutionary biology

... generation time of some microbes to answer evolutionary questions. Similar features have led to progress in viral evolution, particularly for bacteriophage . Notable evolutionary biologists Notable contributors to evolutionary biology include: Charles Darwin Erasmus Darwin Richard ...

Genetics

... the first time by Fred Sanger , Walter Gilbert , and Allan Maxam working independently. Sanger's lab complete the entire genome of sequence of bacteriophage Φ-X174; . 1983 Kary Banks Mullis discovers the polymerase chain reaction enabling the easy amplification of DNA 1989 The first human ...

Genomics

... related field of genetics is the study of genes and their role in inheritance. The first genome to be sequenced in its entirety was that of bacteriophage FX174 (5,368 kb) in 1980 . The first free-living organism to be sequenced was that of Haemophilus influenzae (1.8Mb) in 1995 , and since then ...

Immune system

... same sequence. Therefore, the bacterium's DNA will not be damaged by the first enzyme because of the presence of the second enzyme. However, when a bacteriophage attempts to infect this bacterium, the viral DNA has not been protected, and gets degraded by the first enzyme. While study of the bacterial immune ...

Max Delbr

... US during World War II , teaching physics at the Vanderbilt University in Nashville . In 1939, he co-authored a paper called The Growth of bacteriophage with E.L. Ellis in which they demonstrated that viruses reproduce in "one step ", rather than exponentially as cellular organisms do. In ...

Microbiology

... petri dish to analogous locations on several other petri dishes. After replicating a plate of E. coli , they exposed each of the new plates to a bacteriophage (also called phage). They observed that phage-resistant colonies were present at analogous locations on each of the plates, allowing them to ...

Phage

... A phage (also called bacteriophage ) (in Greek phageton = food/consumption) is a small virus that infects only bacteria . Like viruses that infect eukaryotes , phages consist ...

Virus

... term virus usually refers to those particles which infect eukaryotes (multi-celled organisms and many single-celled organisms), whilst the term bacteriophage or phage is used to describe those infecting prokaryotes ( bacteria and bacteria-like organisms). Typically these particles carry a small ...
