Cells contain machinery that duplicates DNA into a new set that goes into a newly formed cell. That same class of machines, called polymerases, also build RNA messages, which are like notes copied from the central DNA repository of recipes, so they can be read more efficient...
What is RNA sequencing How is polycistronic messenger RNA transcribed? How does an RNA virus work? Why is there no thymine in RNA? Why does DNA need RNA? What is the role of RNA? Describe how the DNA code is translated into messenger RNA ...

5、梅毒抗体或人类免疫缺陷病毒(HIV)阳性者,或活动性乙型肝炎者(乙肝表面抗原阳性且HBV-DNA高于参考值上限)或丙型肝炎者(丙肝病毒抗体阳性且HCV-RNA高于参考值上限),或2019年新型冠状病毒(新冠肺炎)感染者。 6、研究药物首次给药前4周内接受过其他临床试验药物者。 7、研究药物首次给药前4周内接受过化疗、放疗、...
DNA is encoded ('transcribed) into mRNA and then decoded ('translated) into Proteins. Along the way alot of good and bad stuff happens in thelatent space. To make the DNA -> RNA transcribing happen - RNA takes a DNA strands - the template strand that runs from 3' to 5' (prime) -...
未来收集生物标本,如脑脊液和血清/血浆,可能实现微创诊断和使用microRNA表达水平进行疾病监测,也可以通过循环肿瘤DNA分析识别存在的肿瘤突变,这可能为预后和/或新的治疗策略提供信息。成功地开发调控异常的分子通路将非常重要。相互排斥的KIT...

aWhen RNA is used as template, by initially adding the reverse transcriptase, one-step process from cDNA generation to DNA amplification can be achieved. 当RNA使用作为模板时,通过最初增加反向transcriptase,一步过程从cDNA世代到脱氧核糖核酸放大作用可以达到。 [translate] ...
viruses tend to have single-stranded RNA and bacteriophages tend to have double-stranded DNA.Most importantly, RNA virus must have Reverse transcriptase to synthesize DNA, the DNA are ready to integrate into host DNA.DNA viruses are not necessary to have the Reverse transcriptase....
(Fig. 1), each step needs specific Cas proteins encoded by the cas genes near the CRISPR array, together with other accessory proteins. The CRISPR-Cas adaptation stage involves the identification and extraction of the protospacer from the invading DNA/RNA and its subsequent incorporation into the...
