DNA is self-replicating,which means that each strand of DNA acts as a template for the creation of new strands. RNA primer is used to initiate the replication process. During replication, first the double helix "unzips," exposing the two DNA strands. (This is done by an enzyme called heli...
四、原核生物转录终止:ρ-dependent VS ρ-independent 依赖ρ 因子的 termination ρ 因子: 同六聚体 pro,亚基 64kD 能与RNA 结合,对 polyC 结合力强 原理: RNA 3‘的 polyC 结合 ρ 因子,RNA pol 移动停止 ρ有解旋酶活性,解旋 RNA/DNA杂化双链 非依赖 ρ 因子的 termination 3’ polyU 结构,上游GC...
The DDR comprises multiple pathways, each of which recognises and resolves specific types of DNA damage. Such damage includes large nucleotide adducts, which are resolved by nucleotide excision repair; small lesions, resolved by base excision repair;7,8and double-strand breaks (DSBs), resolved by ...
通过三维比对,将新识别的病毒RdRP与已知的病毒RdRP、真核生物的RdRP(Eu RdRP)、真核生物DNA依赖的RNA聚合酶(Eu DdRP)和RT进行了结构相似性比较,显示出与已知RNA病毒蛋白相比显著更高的结构相似性。在实验中,对从南极等地采集的50多个样本同时进行DNA和RNA...

--fr 链特异性建库方式:fr-secondstrand(如 Ligation,Standard SOLiD). 解释代码 这段代码是一个简单的bash脚本,用于处理一组.bam文件,并使用StringTie进行转录组组装(assembly)。 解释每个部分的作用: cd ~/lncRNA_analysis/3_alignment: 进入路径~/lncRNA_analysis/3_alignment,即切换到指定的目录下。 for i...
(Supplementary Fig.7). Thus, it is also possible that the editing occurs in the DNA strand, as suggested in vitro39, albeit how frequently and whether this happens in the context of DNA repair is still unclear. Editing of the DNA strand would greatly increase the mutagenesis associated with...

StrandBrite 绿色荧光RNA定量试剂盒是美国AAT Bioquest生产的RNA检测试剂盒 ,检测和定量少量RNA对于各种分子生物学程序非常重要,例如测量体外转录RNA的产量和测量RNA浓度,然后进行Northern印迹分析,S1核酸酶测定,RNase保护测定,cDNA文库制备,反向转录PCR和差异显示PCR。最常用的测量核酸浓度的技术是测定260nm处的吸光度。基于...
相比 于低温条件下反转录反应,采用高温反转录可显著打开 RNA 二级结构,从而提高复杂 RNA 模板的扩增性能、提高反转 录 cDNA 的长度和产量,从而提高后续检测的灵敏度。合成 的链 cDNA 可广泛用于 2nd Strand 的合成、杂交、PCR 扩增、Real-Time PCR 反应等。
