These molecules can be administered intravenously and bind selectively to the portion of the target DNA to be modified. Once bound, the chimeraplast activates a naturally occurring gene-correcting mechanism, which modifies the DNA at the target site precisely. This process is still experimental. A portion of a chromosome taken as a unit under given circumstances. The DNA in a cell is divided into structures called chromosomes.
Chromosomes are large enough to be seen under a microscope.
In each pair of chromosomes, one chromosome is inherited from an individual's father and one from his or her mother. Cloning of genes and cells to create many copies in the laboratory is a common procedure essential for biomedical research. The laboratory cloning of a sheep using the genetic material from a cell of an adult animal has recently been reported. A variant strain of mice that differs from an established inbred strain by mutation at only a single locus. A technique for rapidly and systematically assembling a variety of molecular entities, or building blocks, in many different combinations, to create tens of thousands of diverse compounds that can be tested in drug discovery screening assays to identify potential useful candidates.
