Question

Illustrate tobacco mosaic virus and bacteriophage​

Answer 1

Tobacco Mosaic Virus (TMV):

Tobacco mosaic virus has a rod-like appearance. Its capsid is made from 2130 molecules of coat protein (see image to the left) and one molecule of genomic single strand RNA, 6400 bases long.

Bacteriophage:

Life cycles of bacteriophages During infection a phage attaches to a bacterium and inserts its genetic material into the cell. After that a phage usually follows one of two life cycles, lytic (virulent) or lysogenic (temperate). Lytic phages take over the machinery of the cell to make phage components.
