DNA template could explain evolutionary shifts
...in humans or microhomology-mediated break-induced replication (MMBIR) in simpler models generated genomic rearrangements ranging in size from several megabases
to a few hundred base pair during normal cell division, resulting in the duplication or even triplications of individual genes or the rearrangements o...
Plant geneticists find veritas in vino
...a Pinot Noir grape by an Italian-based multinational consortium.
The genome of the grape is spread over 19 pairs of chromosomes and is around 504.6 megabases
in length. The team of researchers, led by Dr Riccardo Velasco of the Istituto Agrario di San Michele all'Adige, used a shotgun sequencing approach, w...
Exploring the dark matter of the genome
...of the Berkeley Drosophila Genome Project (BDGP). "Over a third of the total DNA in a fruit fly is heterochromatin. The female fly has an estimated 60 megabases
of heterochromatin" -- a megabase (Mb) is a million bases, the nucleotide building blocks of DNA -- "and the male has an estimated 100 Mb, because the...
New plant DNA libraries provides massive boost to world's plant researchers
The new plant DNA libraries include:
Aloe Vera - a plant with interesting medicinal properties and a DNA structure made up of 16,000 megabases
(by comparison a human's DNA structure consists of 3,000 megabases)
Catharanthus roseus - a plant which is the only source of two key drugs (vincri...
Major histocompatibility complex
...region or gene family found in most vertebrates containing many genes with important immune system roles. In humans , the MHC spans almost 4 megabases
of chromosome 6 and includes more than 200 known genes, of which about half have known immmunological functions.
...ic proteins .
In the 24 April 2003 issue of Nature , the genome of N. crassa was reported as completely sequenced . The genome is about 43 megabases
long and includes approximately 10,000 genes.
In its natural environment, N. crassa lives mainly in tropical and sub-tropical regions. It can be f...
