DNA is the stuff of life. It is inevitable that the more we research, the more we will understand about ourselves and the living world, and the more power we will have to change it. All this work with DNA will give insights into...
due to the chemical structures of the bases—the pair is like a rung or step on a spiral staircase. This means that the two strands of the double helix can be separated, and new strands can be formed that copy

the Evolution of VirusesGiant Virusesthe Simplest Bacteriathe Last Universal DNA Molecule.Since viruses are the first form of life on Earth, it can be shown that it was viruses that formed and spread biological life on the planet. The evolutionary tr...
This is a super easy tool to use to view which surnames are clustered with and upstream of your haplogroup. With Family Finder haplogroups being assigned now, I check my upstream haplogroups almost daily to see what has been added. For example, my Big Y Estes results are ten branches belo...
Crocodilians are one of the oldest extant vertebrate lineages, exhibiting a combination of evolutionary success and morphological resilience that has persisted throughout the history of life on Earth. This ability to endure over such a long geological time span is of great evolutionary importance. Here...
double helix 2 interesting facts from james watson tedtalk video 1. when watson & crick figuered out dna structure of double helix, got insight onto dna replication 2. dna can be used for comparison in cancer. mutation--> cancer 3. in autism, genes missing. autism linked to mutated ...
近日,军事医学研究院伯晓晨和郑晓飞团队在Briefings in Bioinformatics杂志上发表方法学综述:Computational methods for the prediction of chromatin interaction and organization using sequence and epigenomic profiles,分类总结了基于DNA序列和基因组表观修饰信息预测染色质相互作用和高级结构的48种计算方法,评估了不同方法的...
Actually, there is some truth to that startling statistic, but it's not the whole truth. This piece of info likely originated from a program run by the National Human Genome Research Institute back in 2013, although other similar data may have been run elsewhere. This particular effort was ...
Deoxyribonucleic acid (DNA) is the blueprint of life, and cost-effective methods for its long-term storage could have many potential benefits to society. Here we present the method of in situ cryosilicification of whole blood cells, which allows long-term preservation of DNA. Importantly, our ...
