MBOC is the book you're looking for by Alberts: https://www.amazon.com/Molecular-Biology-Cell-Bruce-Alberts/dp/0815344325/ref=sr_1_2?ie=UTF8&qid=1519168605&sr=8-2&keywords=molecular+biology+of+the+cell https://www.amazon.com/Molecular-Biology-Cell-Bruce-Alberts/... It's standard reading at the very least as intro grad/senior undergrad student in the biosciences. Great book, well written, well curated. Parent commenter is correct, DNA->function is massively complicated. The main wiki article to start with is: https://en.wikipedia.org/wiki/Central_dogma_of_molecular_biology https://en.wikipedia.org/wiki/Central_dogma_of_molecular_bio... As the article notes, there are endless exceptions and edge cases. It links to various examples of those.
