Ticking over: circadian systems across the kingdoms of life

The ability to anticipate the day–night cycle and direct physiology accordingly has proven to be a general phenomenon across all kingdoms of life. Considerable fitness benefits are conferred by an internal 24‐hour clock, which is known as a circadian clock. Extensive multi‐disciplinary studies in a range of model organisms have elucidated many of the components involved in generating and sustai...

“the effect of risk aversion on the demand for life insurance: the case of iranian life insurance market”

abstract: about 60% of total premium of insurance industry is pertained?to life policies in the world; while the life insurance total premium in iran is less than 6% of total premium in insurance industry in 2008 (sigma, no 3/2009). among the reasons that discourage the life insurance industry is the problem of adverse selection. adverse selection theory describes a situation where the inf...

Only six kingdoms of life.

There are many more phyla of microbes than of macro-organisms, but microbial biodiversity is poorly understood because most microbes are uncultured. Phylogenetic analysis of rDNA sequences cloned after PCR amplification of DNA extracted directly from environmental samples is a powerful way of exploring our degree of ignorance of major groups. As there are only five eukaryotic kingdoms, two clai...

The link between CG methylation and depletion across the kingdoms of life

DNA methylation occurs in prokaryotes and eukaryotes, but in different forms and with different functions. In prokaryotes, methylation is very diverse. Mechanistically, the modification can affect the N4 or C5 of cytosine or N6 of adenine. Sequence context is variable. Functionally, methylation plays a role in restriction modification systems, in DNA repair for the distinction of parental and d...
