How can intact DNA be obtained from a solution of DNA and RNA?
Step by step
Solved in 3 steps
- What is the difference between a template strand and adaughter strand of DNA?1) RNA lacks the stability of DNA. Why? a) It has an unmethylated uracil. b) It is originally produced as a single-strand. c) It has one more hydroxyl group that DNA does. d) All the answers are correct! 2) As a newly hired researcher at Johns Hopkins, the nation's leading medical institute, your new boss asks you what would be the quickest mechanism to separate a sample of RNA molecules into siRNA versus lncRNA. Your response to her would be... a) 'Lady, are you crazy! It's not possible!' b) 'I can run them out on a gel and the smaller siRNA molecules will gravitate further down the gel while the larger lncRNA will stay behind!' c)'I can run them out on a gel and the larger siRNA molecules will gravitate further down the gel while the smaller lncRNA will stay behind!' d) 'I can design primers and amplify the RNA samples, which we can then sequence to get the actual RNA reads to determine which ones are shorter like siRNA and which ones are longer like lncRNA.'1)The percentage of adenine in a sample of a DNA molecule is 35%. So, the percentage of thymine should be: a)65% b)35% c)53%
