"A bacteriophage is like a virus for bacterial cells.in the same way that viruses (eg adenoviruses) can be used as vectors to transfer genetic information into eukaryotic cells, a bacteriphage could be used to transfer a gene which confers for example, penicillin resistance, into a bacterium. This gene is expressed and the bacterium is resistant to the given antibitoic."
"Clearly we are in doubt as to
the proper criterion of life.
D'Herelle says that the bacteriophage is alive, because, like the
flea or the tiger, it can multiply
indefinitely at the cost of living
beings. His opponents say that it
can multiply only as long as
its food is alive, whereas the
tiger certainly, and the flea
probably, can live on dead products of life. They suggest that
the bacteriophage is like a book
or a work of art, which is
constantly being copied by living beings, and is therefore only
metaphorically alive, its real life being in its copiers."
"A typical bacteriophage is like a tadpole and consists of two parts i.e. interior and posterior parts."
"A bacteriophage is like a self-replicating viral smart bomb, a virus capable of infecting and destroying specific bacterial cells. Bacteriophages attach to bacteria and inject their DNA into the cell. The DNA instructs the bacteria to produce millions of new virus cells, causing the bacteria cell to burst. With concerns about increasing resistance to antibiotic therapy, there has been an upsurge recently in bacteriophage research."
METAMIA is a free database of analogy and metaphor. Anyone can contribute or search. The subject matter can be anything. Science is popular, but poetry is encouraged. The goal is to integrate our fluid muses with the stark literalism of a relational database. Metamia is like a girdle for your muses, a cognitive girdle.
