1.A linear strand of DNA and associated proteins in the nucleus of eukaryotic cells that carries the genes and functions in the transmission of hereditary information. 2.A circular strand of DNA in bacteria and archaea that contains the hereditary information necessary for cell life. ...
divides, its chromosomes shorten by that much, but as it’s only part of the telomeres that is lost it doesn’t matter. The length of a cell’s telomeres is thought to be linked to its capacity for replication, so telomeres are of great interest in the field of cell ageing and ...

In a human cell that's busy doing its job—such as being a muscle cell, for example—the chromosomes are locked up in a cellular vault called the nucleus. The nucleus keeps the chromosomes—and the genes they contain— safe from outside interference. When a cell is ready to split into ...

Intelligence Quotient tests tend only to examine the first three "intelligences" and hence its demise as a tool of measurement in education. This fits better with the "Outcomes" approach to education where students are recognised to have specific abilities. These intelligences are likely to be ...

Furthermore, unlike Sry, DMY appears to have arisen from duplication of the autosomal DMRT1 gene and its insertion into LG 1 (Kondo et al., 2006). This event suggests that any chromosome could have become the sex chromosome in the ancestor of medaka. Plasticity of sex chromosomes in lower...
