Play Phylo – help the geneticists
You put together a puzzle, and at the same time – compare the sequences of nucleotides in the genes of different organisms. You have a chance to beat the supercomputer!

02.12.2010Gallop through biology news: epigenetics, biology of sex differences, biodiversity and gene copyrights.
11.11.2010How do proteins that regulate the activity of genes in a cell "know" at what point and which gene should be turned off, and how do temporarily disabled genes remain in chromosomes for several generations?
28.10.2010Each person has an average of 50-100 mutations associated with hereditary diseases. This is one of the conclusions made after the first stage by the participants of the 1000 Genomes project.
28.10.2010Recombination of genes makes possible the genetic diversity of people. Jeffries and colleagues were able to localize the DNA regions where most of the recombinations occur and isolate the gene that encodes the protein that provokes this phenomenon.
08.09.2010A third, even more expanded version of the human genome variation map has been published. This will help scientists in the future to better interpret the results of studies aimed at finding the genetic nature of serious diseases.
03.09.2010The development of malignant tumors in the body is opposed by the anti-cancer protection system. Its main participant, the anti-oncogene p53, has been known for a long time, but until now scientists did not understand what makes it activate.
25.08.2010According to new data, taking into account the latest achievements in the field of population genetics, "mitochondrial Eve" lived about 200 thousand years ago. Previously, the age of the hypothetical mother of mankind was estimated at 140 thousand years.
23.08.2010The staff of Bar-Ilan University (Israel) observed in real time in human cells the process of protein production corresponding to a single gene.
21.07.2010The main idea of the international 10K Genomes project is to read ten thousand genomes of different vertebrate species. This is more letters than all the books in the Library of Congress, the National Library of China and our Leninka contain.
05.07.2010Taking into account the 12 new ones, the total number of known "diabetes genes" has reached 38, but each of them has only a very small effect on the risk of type 2 diabetes. Even taken together, they are not able to provide a clear forecast.
28.06.2010A discouraging conclusion drawn from the results of a gigantic work: the genomes of three pairs of identical twins, one of whom has multiple sclerosis, and the other does not, do not differ in any way.
25.06.2010Dozens of tests have been developed to determine the predisposition of dogs and cats to genetically determined diseases and genes that determine the color and length of the coat. Such a gene analysis can be done both in Russia and in the former Soviet republics.
24.06.2010By the end of the 30s, medical genetics in the USSR met the highest international standards. But its development was abruptly interrupted, and until now medical genetics in Russia is noticeably lagging behind the level of developed countries.
22.06.2010During the third phase of the 1000 Human Genomes project, DNA sequences of 179 more people were determined in addition to the first six genomes.
22.06.2010The new DNA sequencing technology, according to the developers of the microfluidic chip, will allow reading a personal genome, spending reagents for only 30 dollars
15.06.2010Genetic tests have become very fashionable. So much so that the companies that offer them have problems.
09.06.2010The development of a method that allows the sequencing of the genome to read the sequence of nucleotides of an entire DNA molecule, rather than cut into fragments, may soon make reading an individual genome a routine procedure.
02.06.2010Genetic tests will become a daily reality in Russia in 10-15 years. Russians will be defenseless against companies that have bet on genetic testing.
31.05.2010The frequency of mutations is determined not by the localization of a DNA fragment on a chromosome, but by the features of the DNA sequence itself, in particular, the content of CpG duplets in it.
