2023-09-18 Thread Natesh Ramanathan
Dear Fu Xingke, Depends on what Nucleic Acid you are talking of. If it is RNA, you can expect some sequence to tertiary structure correspondence so you might be able to try more MR as compared to DNA. DNA may have double helical architecture but less sequence to tertiary structure corr

I absolutely agree with Guenter. This non experts speaking wrong things is increasingly happening nowadays. Thanks Guenter, for pointing this out. A theory unless it is given experimental data derived evidence it is still a prediction (just like weather prediction, unless it is realised in the p
