Pus Cells in Urine. 1  The presence of pus cells in the urine indicates an ailment in the body. 2  Pus cells are white blood cells that signify infection in the body, especially if the urine also contains bacteria.  Presence of pus cells in the urine may also be a sign of infection or inflammation in the kidneys and bladder. Since the urine has to pass through the kidneys and the bladder, it may pick up some pus cells from there before voiding.
DNA sequencing is the process of determining the precise order of nucleotides within a DNA molecule. It includes any method or technology that is used to determine the order of the four basesâ adenine, guanine, cytosine, and thymine âin a strand of DNA.The advent of rapid DNA sequencing methods has greatly accelerated biological and medical research and discovery.NA nanoball sequencing is a type of high throughput sequencing technology used to determine the entire genomic sequence of an organism. The company Complete Genomics uses this technology to sequence samples submitted by independent researchers.
Equally important and coupled with DNA methylation is DNA demethylation, the removal of a methyl group. The demethylation process is necessary for epigenetic reprogramming of genes and is also directly involved in many important disease mechanisms such as tumor progression.hen a CpG island in the promoter region of a gene is methylated, expression of the gene is repressed (it is turned off). The addition of methyl groups is controlled at several different levels in cells and is carried out by a family of enzymes called DNA methyltransferases (DNMTs).
