The molecular mechanism of thymineless death remains unknown; [1] DNA breaks were observed during thymineless death, which could explain the killing. [ 8 ] [ 9 ] Possible pathways involved with the killing mechanism include: replication initiation, [ 8 ] [ 10 ] breakage of ongoing replication forks, [ 11 ] futile DNA repair, [ 9 ] replication ...
The Journal of Bacteriology is a monthly peer-reviewed scientific journal established in 1916. It is published by the American Society for Microbiology and the editor in chief is George A. O'Toole Jr. ( Dartmouth College ).
Most of the cell's macromolecules are affected by ionising radiation, but damage to the DNA macromolecule is most often the cause of cell death, since DNA often contains only a single copy of its genes; proteins, on the other hand, often have several copies so that damage of one will not lead to cell death, and in any case may always be re ...
Stationary phase results from a situation in which growth rate and death rate are equal. The number of new cells created is limited by the growth factor and as a result the rate of cell growth matches the rate of cell death. The result is a “smooth,” horizontal linear part of the curve during the stationary phase.
Overview of signal transduction pathways involved in apoptosis. Cell death is the event of a biological cell ceasing to carry out its functions. This may be the result of the natural process of old cells dying and being replaced by new ones, as in programmed cell death, or may result from factors such as diseases, localized injury, or the death of the organism of which the cells are part.
For many years, neither "apoptosis" nor "programmed cell death" was a highly cited term. Two discoveries brought cell death from obscurity to a major field of research: identification of the first component of the cell death control and effector mechanisms, and linkage of abnormalities in cell death to human disease, in particular cancer.
Unsolved problems relating to the structure and function of non-human organs, processes and biomolecules include: Korarchaeota (archaea). The metabolic processes of this phylum of archaea are so far unclear. Glycogen body. The function of this structure in the spinal cord of birds is not known. Arthropod head problem. A long-standing zoological ...
