Viernum said, âBlack mambas are one of the fastest species of snakes, reaching slithering speed up to 12 mph [19 kph].â This is undoubtedly fast, but still slower than the myths of them outrunning horses would suggest. Over longer distances, they average about 7 mph (11 kph).
A bacteriophage, or a phage, is a virus that infects bacteria, so these don't infect human cells âthey are very specialised and only infect bacteria. So every bacteria is being attacked by various viruses which are using those as the host that they replicate in.
In the lysogenic cycle, the phage's DNA recombines with the bacterial chromosome. Once it has inserted itself, it is known as a prophage. A host cell that carries a prophage has the potential to lyse, thus it is called a lysogenic cell. The image above illustrates both the lytic and lysogenic cycles of a bacteriophage. bacteriophage is a virus that infects bacteria. Bacteriophages, first discovered around 1915, have played a unique role in viral biology.
