I am just starting to approach bioinformatics, I have some basic knowledge about mRNA, DNA, transcription, translation, etc. and computer science knowledge of R and programming. But I am not good at (or I can say I am not clear about) long non-coding RNA, etc. I want to find a book/ebook that can help me develop knowledge in bioinformatics. Something can be "theoretical" that can explain fundamental in biology and computer science. I need the one that help me with basic definitions, how can they be "translated" into computation. Thanks in advance!
