青岛科技大学DNA合成方法取得突破
青岛科技大学 DNA合成方法
2015/11/13
日前，青岛科技大学化学与分子工程学院马翠萍课题组发现了几种DNA聚合酶具有内在的反转录酶活性，突破了DNA聚合酶只能以DNA为模板合成DNA的传统认知，对RNA的快速检测具有重要意义。该成果在线发表于《美国化学会志》。
中国科学院昆明动物研究所在猪lincRNA基因DNA甲基化研究中取得新进展

DNA double strand breaks (DSB), particularly those induced by ionizing radiation (IR) are complex lesions and if not repaired, these breaks can lead to genomic instability, chromosomal abnormalities a...
The influence of the Ku80 carboxy-terminus on activation of the DNA-dependent protein kinase and DNA repair is dependent on the structure of DNA cofactors
DNA-PK Ku70/80 Ku80 Carboxy Terminus
2015/5/25
In mammalian cells DNA double strand breaks (DSBs) are highly variable with respect to sequence and structure all of which are recognized by the DNA- dependent protein kinase (DNA-PK), a critical comp...
