Forensic Serology Information Page
What is Forensic Serology?According to forensic serologist Marcella Jones of www.ForensicMentor.com, forensic serology is the analysis of body fluids as they relate to forensic cases, including DNA analysis. Accordingly, the role of the forensic serologist involves:Examining evidence for the presence of body fluids e.g. blood, semen, hair, tissue, saliva, feces, and urineEvaluating evidence for potential DNA analysisEvaluating species of body fluidsPerform PCR (polymerase chain reaction) based typing of STR (short tandem repeat sequences) of genomic DNA, or mitochondrial sequence analysis of [more...]

Natural Diet and Lifestyle Reverse the Effects of Aging | Health News
While DNA and genetics play a minor role, poor diet and lifestyle directly contribute to the leading causes of mortality, coronary artery disease, cancer, stroke, and dementia. Fortunately we can steer our destiny toward optimal health even after years of dietary and lifestyle abuse by addressing each identified aging factor. Neutralizing the Effects of Free Radicals Free radicals are unstable electrons produced during the normal course of metabolism, causing damage to the delicate cell nucleus and mitochondria. Free radicals can wreak havoc with DNA, altering its structure and causing [more...]

For instance, in a recent issue of the Journal of Theoretical Biology, John Bodnar describes how "non-coding DNA in eukaryotic genomes encodes a language which programs organismal growth and development." Design encourages scientists to look for function where evolution discourages it. (William Dembski, "Intelligent Science and Design," First Things, Vol. 86:21-27 (October 1998))In 2002, Dr. Richard Sternberg surveyed the literature and found extensive evidence for function of certain types of junk-DNA and argued that "neo-Darwinian 'narratives' have been the primary obstacle to elucidating [more...]

Dr. Falk appears to be too hasty in his assumption that pseudogenes have "no function" and thereby show evidence for common ancestry. The bottom line is that the "junk" or "gibberish" DNA paradigm is being consistently overturned as time goes on, and we now know that the vast majority of our DNA has function. As one news article said when reporting on the results of the ENCODE project in 2007: The findings, from a project involving hundreds of scientists in 11 countries and detailed in 29 papers being published today, confirm growing suspicions that the stretches of 'junk DNA' flanking [more...]

Novel Protein Critical for Cellular Proliferation Discovered ...
In addition to its role in DNA replication, ORC is also involved in gene silencing and organization of the tightly packed DNA, called heterochromatin. How ORC is brought to the DNA in human cells had previously remained a mystery. Researchers at the University of Illinois, led by Professor Supriya Prasanth from the school of molecular and cellular biology, have identified a novel protein that is highly conserved in higher eukaryotes. They have shown that in human cells, this protein (once known as LRWD1 but renamed ORCA, for "ORC-associated" protein) associates with ORC and shows similar cell [more...]

In 1953, the molecular structure of DNA was discovered by Watson and Francis Crick.

Association between the Herpes Simplex Virus-1 DNA Polymerase and ...
Moreover, UL30, in conjunction with the viral uracil DNA glycosylase (UL2), cellular apurinic/apyrimidinic endonuclease, and DNA ligase IIIα-XRCC1, performs uracil-initiated base excision repair. Base excision repair is required to maintain genome stability as a means to counter the accumulation of unusual bases and to protect from the loss of DNA bases. Here we show that the HSV-1 UL2 associates with the viral replisome. We identified UL2 as a protein that co-purifies with the DNA polymerase through numerous chromatographic steps, an interaction that was verified by [more...]

FAN1 glommed onto sites of the DNA damage. The researchers found that when they induced a mutation in the UBZ domain of the gene, it was rendered useless, meaning its restorative ability likely lies in its capacity to interact with ubiquitinated proteins in the Fanconi anemia pathway. As predicted, the nuclease domain of FAN1 was able to cut DNA, activity that is essential repairing the broken zippers. Versions of the gene are present in distantly related organisms, from yeast to flies to humans, Smogorzewska says, suggesting a role in lifes fundamental machinery for repairing DNA. The [more...]

The role of EZH2 and DNA methylation in the silencing of the ...
Conversely, downregulation of RUNX3 mRNA in the same tumours was associated with RUNX3 DNA methylation (P < 0.05). In cell lines, knockdown of EZH2 removed the repressive chromatin marks from RUNX3 but did not result in RUNX3 re-expression. However, it prevented the re-silencing of RUNX3 after the removal of demethylating agents. In conclusion, DNA methylation is primarily responsible for the transcriptional silencing of RUNX3 in CRC, but EZH2 and histone methylation are necessary for its methylation-dependent re-silencing after the removal of demethylating agents. These results would predict [more...]

Raising The Alarm When DNA Goes Bad | Discuss Cancer
Histones play a major role in assembling chromatin and keeping it together, but they don’t usually have macrodomains,” says Ladurner. “The finding is particularly relevant, because it turns out that cancer cells don’t have macroH2A1.1. The fact that one member of the rapid response team that detects DNA damage is missing could contribute to the disease.” Because macroH2A1.1 is embedded in chromatin, when it recognises PAR at DNA damage sites, it drags the complex but highly-organised tangle of chromatin with it. As a result, macroH2A1.1 condenses the chromatin environment around the [more...]

Role of p400/mDomino in Cell-cycle Progression [Dna and Chromosomes]
DNA microarray analysis revealed that the p400/mDomino deletion from MEFs caused the impaired expression of many cell-cycle-regulatory genes, including G2/M-specific genes targeted by the transcription factors FoxM1 and c-Myc. These results indicate that p400/mDomino plays a key role in cellular proliferation by controlling the expression of cell-cycle-regulatory genes.

In most cells, 100-1000 Okazaki fragments are produced for each replicative DNA polymerase present in the cell. For fast-growing cells, this necessitates rapid recycling of DNA polymerase on the lagging strand. Bacteria produce long Okazaki fragments (1-2 kb) and utilize a highly processive DNA polymerase III (pol III), which is held to DNA by a circular sliding clamp. In contrast, Okazaki fragments in eukaryotes are quite short, 100-250 bp, and thus the eukaryotic lagging strand polymerase does not require a high degree of processivity.

DNA is synthesized from four deoxynucleotide triphosphates. The top formula shows one of them: deoxythymidine triphosphate (dTTP). Each new nucleotide is added to the 3′ -OH group of the last nucleotide added. Link to discussion of DNA synthesis. The dideoxy method gets its name from [more...]

Histones are proteins found in the nucleus that package and order DNA into structural units. Epigentic changes alter how DNA folds in chromosomes, changing how accessible genes are to regulatory proteins and enzymes that copy genes into RNA messages."Epigenetics is the study of how factors outside of actual DNA interact with, but not alter, genes.
