In fact, these traits are precisely what make a cell a cell. What Defines a Cell? Figure 1: Transport proteins in the cell membrane A plasma membrane is permeable to specific molecules that a cell needs. Transport proteins in the cell membrane allow for selective passage of specific ...
What is a Cell? A cell is the structural and fundamental unit of life. The study of cells from its basic structure to the functions of every cell organelle is called Cell Biology. Robert Hooke was the first Biologist who discovered cells. All organisms are made up of cells. They may be...
Traditions of medicine, collective knowledge from physicians, works of prominent historical figures such as Aristotle eventually coalesced into the field of study we know today as biology. The most significant revolutions in biology came during the 19th century, with a host of discoveries and technolog...
During a lytic infection the host cell does what? What is mast cell disease? What is meant by "causative microorganism"? What is another name for lymphocytes that produce antibodies? What types of pathogens do killer T-cells kill? What type of t cell directly attacks infected cells? What is...
Cell culture is the process in which cells are removed from a host organism and grown in an artificially created environment. This can be done to study the characteristics of the cells, or to use them as a medium in which to grow particular diseases for study. ...
Poor exercise capacity is the most powerful predictor of mortality and there is evidence for the prescription of exercise as therapy for many diseases. There has been an increasing appreciation that exercise transiently stimulates th...

The protein that confers immunity on the host cell is encoded by the cvi gene [78]. Gene clusters similar to known bacteriocins have been described in other Aeromonas genomes [79], and the receptor for ferrienterochelin and colicins was identified in A. salmonicida subsp. pectinolytica 34...
We used Monte Carlo simulation to obtain p-values without assuming asymptotically normal behaviour from small cell count (degrees of freedom do not go into the equation at any stage of the computation, so there is no reason to report them). Specifically, we tested the independence between “...
Viruses are tiny infectious agents composed of a type of nucleic acid, which can be either DNA or RNA, enclosed by a protein coat. Viruses cannot reproduce on their own, and they need to infect a host cell to make copies of themselves. Retroviruses are viruses whose genetic material is com...
