Darwin's theory of natural selection provides an explanation for why organisms develop traits that help them survive and reproduce. Because of this, death is often seen as a failure rather than a ...

Whilst the ultimate outcome of the lytic cycle is production of new phage progeny and death of the host bacterial cell, this is a multistep process involving precise coordination of gene transcription ...

Strominger, J.L. Penicillin-sensitive enzymatic reactions in bacterial cell wall synthesis. in Harvey Lectures, Series 64 179–213 (Academic Press, New York, 1970). Google Scholar ...

The arrangement of atoms in an enzyme molecule has been worked out for the first time. The enzyme is lysozyme, which breaks open cells of bacteria. The study has also shown how lysozyme performs ...

The cell wall of most bacteria has an overall net negative charge and thus can be stained directly with a single basic (positively charged) stain or dye. This type of stain allows us to observe the ...

Viruses that infect bacterial cells are called bacteriophages. Their main goal is to produce more bacteriophages by injecting their genome into a bacterial host cell, using the host cell machinery ...

Two molecules can have the same chemical composition and arrangement while being ... Likewise, mirror bacteria have been proposed for live-cell therapeutic techniques, but alternative technologies ...

Jon Chase: Bacteria are a type of microorganism, each made up of just one cell. Some bacteria are harmful and cause disease, and some are useful, like the one hundred trillion bacterial cells that ...
