Chromosome glue repairs damaged DNA
...tumour cells. Dr Camilla Sjgren and her research team have now shown that the cell also employs cohesion to repair damaged sister chromatids. Their results show that DNA damage can reactivate cohesin, which runs counter to the commonly held view that cohesion only arises during the DNA copying that take...Liverpool amongst first in UK to install unique DNA sequencing technology

The research team studied a repeated genomic sequence called SINE B2, which is located on the growth hormone gene locus, the gene related to the aging process and longevity. The scientists were surprised to find that SINE B2 sequence is critical to formation of the fu...Researchers witness natural selection at work in dramatic comeback of male butterflies
Berkeley -- An international team of researchers has documented a remarkable example of natural selection in a tropical butterfly species that fought back - genetically speaking - against a highly invasive, male-killing bacteria.

A team of John Innes centre scientists lead by Professor Nick Harberd have discovered how plants evolved the ability to adapt to changes in climate and environment. Plants adapt their growth, including key steps in their life cycle such as germination and ...Changing climate will challenge Northeast agriculture, CU expert warns
