Mitochondrial DNA Genealogy

The mitochondrial DNA genealogy is the study of a person’s mother’s family line of maternal ancestors. This DNA is passed down from mother to each of her children exactly as she has it, with no mutations, except in the very rare instances. Because of the traditions in our society of the wife taking her husband’s last name, a surname genealogy trace of the female line of the family tree is more difficult. On the flip side, since this DNA strand is more stable than the Y DNA, more conclusive results can be determined for the testing of it. The mt-DNA is sometimes referred to as the Full [more...]

DNA Tests Indicate Yellowstone National Park Elk, Not Bison, Most ...

A DNA genotyping study conducted in 2009, and which was just recently published in the Journal of Wildlife Diseases, examined samples from 10 bison, 25 elk, and 23 cattle collected in the greater Yellowstone area between 1992 and 2003 and found that DNA markers for Brucella abortus were nearly identical in elk and cattle but "highly divergent" from those in bison. "The data, which suggest that elk rather than bison are most likely the origin of recent outbreaks of brucellosis in Greater Yellowstone cattle, are consistent with the fact that elk comingle with cattle more often than do the wild [more...]

Language Delays Found in Siblings of Children with ...

One striking finding was that among siblings, 20 percent had received a diagnosis of language delay or speech problems early in life. And half of them had particular qualities of speech that are autistic in nature. So the investigators believe that what is aggregating in these families is more than just the full syndrome of autism. In about 11 percent of families, more than one sibling has autism, and in many others, these subtle, quantitative signs and symptoms indicate many undiagnosed children are affected as well. That's important, Constantino says, because in studies involving DNA [more...]

Language Delays Found in Siblings of Children With Autism

When a child has an accumulation of quantitative traits, that child will be diagnosed with autism or a related disorder, but siblings can have subtle quantitative traits without reaching the threshold for a diagnosis. “It’s not an all-or-nothing condition,” Constantino says. “When we look only at the full syndrome for inherited traits, we miss a lot of individuals who may have genetic susceptibility and subtle aspects of autism. In other words, many siblings of children on the spectrum have significant, subclinical traits of autism, but, for whatever reason, they never actually [more...]

Insights into watermelon genetic diversity

Insights into watermelon genetic diversity by Jeremy on September 29, 2010 There’s no doubt that most of the time when we non-experts think of genetic diversity in DNA terms, we think about alterations in the actual DNA sequence. Change the genetic code and there’s a chance you change the nature of a gene and as a result change the outward appearance, the phenotype, of an organism. There have been lots of studies relating the differences among species to differences in the DNA code of this sort, but far fewer looking at the differences among varieties of a single species.

A WOMAN's fashion fate is partly determined at birth by her "apple or pear" genes, research has shown. Scientists have identified 13 new gene regions containing DNA variations linked to body shape. Many have a much stronger effect in women than in men, deciding whether they are more likely to store fat around the middle or bottom of their bodies. Apple-shaped individuals with extra fat around their waists are known to have an increased risk of type 2 diabetes and heart disease.

Unlike genetic changes, which involve a change or mutation in DNA sequence, epigenetic changes in the nucleus leave the DNA sequence unaltered but modify the histone proteins, which comprise the backbone of the chromosome. 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. It is turning out, through [more...]

Why Do Histones Bind Tightly To DNA? | Why

Histones are an important part that helps bind the DNA chromosomes together. They are amino acids that are composed of protein and are positively charged. Since the acidic part of the DNA is negative and the Histones are positively charged, it helps bind the DNA together. Protein interactions play an important role in the functions of the DNA. The five types of Histones are H1 (H5), H2A, H2B, H3, H4 and they are consistently present in all forms of DNA. DNA (Deoxyribo Nucleic Acid) is the genes that a living organism, cell, virus inherits and sometimes referred to as a “blueprint” (basic [more...]

That's important, Constantino says, because in studies involving DNA tests, brain imaging or biological comparisons between affected children and their unaffected siblings, researchers traditionally assume undiagnosed children are unaffected. But this study would suggest that's not necessarily the case.

The whole chimp DNA thing is an example of reporting bias. They like to use the “98% similar” argument. But there are 3 billion letters in the human DNA genome, and they are 98.5% similar with chimps. DNA is fantastically complex, and the math yields 45 million differences. Most of the “science” in the article was based on the unproven assumption that chimps and humans have a common ancestor.

This attempt to justify Zionism through genetics is reminiscent of the procedures of late nineteenth-century anthropologists who very scientifically set out to discover the specific characteristics of Europeans. As of today, no study based on anonymous DNA samples has succeeded in identifying a genetic marker specific to Jews, and it is not likely that any study ever will.

Harvard-MIT study examines Graphene | UWIRE

Pore length is crucial when identifying individual DNA bases, Branton said, adding that the study “represents the first time that a molecule—DNA in our case—has been put through a nanopore that is extremely short.” Scientists in the past have studied protein-based nanopores that span five to 10 nanometers in length. But because the distance between two bases in a DNA molecule is 0.5 nanometers, such pores are ineffective, as they obstruct the resolution of 10 to 15 bases at a time. In contrast, graphene nanopores—which span a length of 0.5 nanometers—allow a single base to occupy [more...]
