1. : a theory in geology: the lithosphere of the earth is divided into a small number of plates which float on and travel independently over the mantle and much of the earth's seismic activity occurs at the boundaries of these plates. 2.
Sperm DNA Fragmentation Test. The genetic integrity of the sperm is crucial for successful fertilization and normal embryo development. Sperm DNA fragmentation is a term used to denote when the genetic material within the sperm is abnormal, which in turn may lead to male subfertility and IVF failure.s a second generation sperm DNA test. It detects the sperm with DNA damage and also tells how much DNA damage each sperm have. A SpermComet test result of 45% means that there is an average of 45% damage in each sperm that was assessed.
According to Dr. Lawrence Koblinsky, a professor of forensic science at John Jay College of Criminal Justice in New York, low copy number DNA profiling, used in the UK on DNA fingerprints, typically uses only 5 to 20 cells.nstead of swabbing the fingerprint off the surface of the paper, DDC scientists cut the fingerprint section from the paper, which was used for DNA extraction. DDC has found that it is easier to obtain DNA from a cut section of paper rather than a swabbed section of paper.
