Why is it important that running buffer for electrophoresis contain some salt (electrolytes)? 1. What purpose does the loading dye serve? 2. What is the purpose of the molecular weight ruler? 3. Analyze whether the DNA extraction column used was a cationic...
Why is DNA polymerase used in PCR? What is an important use of PCR in biotechnology? Give examples. What is the purpose of using washing buffer during RNA extraction? Why do smaller molecules move faster in gel electrophoresis? What are positive and negative controls in gel electrophoresis?
Signs you might have a malware problem How does an average user determine whether their machines are under a malware attack? Successful malware attacks are characterized by their invisibility property. They remain under the radar — even when you’ve installed expensive antivirus tools on your machi...
常伴黄色脓痰，每日40~50ml，夜间体位变动或清晨起床后症状加重，间有咯血，经抗生素治疗后症状好转。此后上述症状反复发作，多以劳累、受凉为诱因，自服抗生素可缓解。2天前淋雨后症状加重，痰量增多，每日150~200ml伴臭味，咯血约每日500ml，患者十分恐惧，担心咯血危及生命，尽量忍住咳嗽。
