Genetic mutation trade-offs lead to parallel evolution
Genetic mutation trade-offs parallel evolution
2017/7/20
Organisms in nature adapt and evolve in complex environments. For example, when subjected to changes in nutrients, antibiotics, and predation, microbes in the wild face the challenge of adapting multi...
A University of Texas at Arlington team exploring pigeons as a model for vertebrate evolution has uncovered that mutations and interactions among just three genes create a wide range of color variatio...
ENU诱导带LacZ靶基因的λgt11 DNA突变分子机理的初步研究①Mutation Study of λgt11 DNA with LacZ Induced by ENU
LacZ基因 突变 体外重包装 诱变剂 DNA测序
2008/1/21
摘要采用ENU(乙基亚硝基脲)作用于裸露的 λgt11 DNA,经体外重包装,转染宿主菌 E. coli Y1090,在含底物X-gal,诱导剂IPTG的选择性培养基上铺皿,发现被处理的 λgt11 DNA除了使噬菌体存活率下降外,还出现了靶基因“LacZ”较高频率的突变。其中以二甲基亚砜(DMSO)为溶剂,当存活率分别为3.5×10-3、1.6×10-3和5.5×10-4 时,相应的突变率依次为...
