Marks of differences between human and chimp genomes

harminka — Thu, 06 Nov 2008 07:55:42 -0600

Researchers have carried out the largest study of differences between human and chimpanzee genomes, identifying regions that have been duplicated or lost during evolution of the two lineages. The study, published in Genome Research, is the first to compare many human and chimpanzee genomes in the same fashion.

Unpicking complexity of human disease

The mysteries of the human genome are slowly being revealed – but the more we uncover the more complicated the picture becomes. This was one key message to emerge from the European Science Foundation's 3rd Functional Genomics Conference held in Innsbruck, Austria, on 1-4 October.

Genome of monkey-human malaria parasite

Researchers have decoded the genome of a malaria parasite that has a host range from monkeys to man. Identified originally in monkeys, the parasite was first reported in a human infection just over 40 years ago.

Researchers investigate the dispensability of our DNA

Our genome contains many genes encoding proteins that are similar to those of other organisms, suggesting evolutionary relationships; however, protein-coding genes account for only a small fraction the genome, and there are many other DNA sequences that are conserved across species.

Molecular biologists have decoded genome of nematode living in beetles

Scientists at the Max Planck Institute for Developmental Biology, together with American colleagues, have decoded the genome of the Pristionchus pacificus nematode, thereby gaining insight into the evolution of parasitism.

Genome communication

In the late 19th century Gregor Mendel used peas to show that one copy of a gene (allele) is inherited from the mother and one from the father. In the progeny, the inherited genes are expressed at the right time and in the right place, but until recently, it was thought that although gene products could be modified during the life of the organism, the genes themselves were unchanged, except for random mutation.

Our genome changes over lifetime

Researchers at Johns Hopkins have found that epigenetic marks on DNA-chemical marks other than the DNA sequence-do indeed change over a person's lifetime, and that the degree of change is similar among family members.

How genes quadrupled during vertebrate evolution

The newly sequenced genome of a dainty, quill-like sea creature called a lancelet provides the best evidence yet that vertebrates evolved over the past 550 million years through a four-fold duplication of the genes of more primitive ancestors.

EuroDYNA leaves healthy genomic research ecosystem as legacy

Europe's position as a major player in genome research has been boosted by the European Science Foundation's three-year EUROCORES programme EuroDYNA.

Superbug genome sequenced

harminka — Thu, 08 May 2008 06:26:13 -0500

The genome of a newly-emerging superbug, commonly known as Steno, has just been sequenced. The results reveal an organism with a remarkable capacity for drug resistance. The research was carried out by scientists at the Wellcome Trust Sanger Institute near Cambridge and the University of Bristol.

Human genome projects offer large-scale picture of genetic difference

harminka — Wed, 30 Apr 2008 14:46:11 -0500

A nationwide consortium led by the University of Washington in Seattle has completed the first sequence-based map of structural variations in the human genome, giving scientists an overall picture of the large-scale differences in DNA between individuals.
