transfer DNA

Microsatellite DNA analysis of inbred mouse somatic cell nuclear transfer blastocysts

近交系小鼠体细胞核移植囊胚的微卫星DNA鉴定

DNA methylation is the only known covalent modification of DNA molecule. It is accomplished by transfer of the methyl group from S-adenosyl methionine to 5 position of the purine ring of cytosine.

DNA甲基化（DNA Methylation）是目前已知的唯一天然的DNA共价修饰方式，由DNA转移酶催化，将S-腺苷甲硫氨酸上的甲基转移到胞嘧啶嘌呤环的第五位碳原子上。

Construction of Recombinant Fowlpox Virus Transfer Vector and DNA Vaccine of GPV and GPMV

GPV与GPMV重组禽痘病毒转移载体和DNA疫苗的构建

A label-free DNA sensor based on the ECL energy transfer mechanism was developed.

构建了一个基于电化学发光能量转移的非标记型DNA传感器。

DNA transfer was studied using pollen tube passage method with wild rice ( Zizania) as donor and rice ( O. Sativa) as recipient.

本试验选用菰（Zizania）作供体，栽培水稻品种为受体，采用花粉管通道法进行DNA转移的研究。

Research progress of foreign DNA transfer and expression in cereal crops

禾谷类作物外源基因导入及表达的研究进展

Methods Antibiotic susceptibility was tested by the disk diffusion to screen out the strains that produced the ESBLs; conjugative transfer test, plasmid profile, PCR and DNA sequencing were used to detect the phenotype or genotype of STEC.

方法采用纸片琼脂扩散法筛选36株产志贺毒素大肠埃希菌产ESBLs菌株，接合传递实验、质粒谱分析、PCR检测耐药基因和DNA序列分析产ESBLs菌株的表型和基因型。

However, phage-resistant starter cultures were traditionally obtained by recombinant DNA technology or conjugal transfer of plasmids confering phage resistance, which holded health potential dangers.

然而，噬菌体抗性菌株通常是通过DNA重组或携带噬菌体抗性基因的质粒的转移获得的，因而赋予所得菌株潜在的安全隐患。

At present, we consider NO released by activated macrophages can kill target cells by restraining the tricarboxylic acid cycle, electron transfer and composition of DNA in target cells.

目前认为，经激活的巨噬细胞释放的NO可以通过抑制靶细胞线粒体中三羧酸循环、电子传递和细胞DNA合成等途径，发挥杀伤靶细胞的效应。
