Biology/DNA and Proteins

Question
What would you use for an equation to show how DNA tells cells to make proteins?
Thanks for using AllExperts, Victoria.
Every person who understands the way DNA works will have a slightly different take on this, but allow me to make some general suggestions.
In molecular biology, the "central dogma" (indeed, this idea is referred to specifically as the central dogma of molecular biology) is this:
DNA-->RNA-->Protein
We can express the same thing by referring to the individual processes, rather than the material used:
Transcription-->Translation-->Protein
Let me propose a more complex one that puts all of the above, plus some more:
DNA-->Transcription-->mRNA (unprocessed)-->Post-transcriptional processing-->mRNA (processed)-->mRNA leaves nucleus-->mRNA binds with ribosome-->Translation-->3D structure of protein forms-->Post-translational processing-->Active protein

Expertise
I will answer all biology-related questions through the undergraduate level. I will explain unclear concepts and suggest approaches to solving problems, but would prefer not to completely solve homework problems for you. If you are completely stumped on homework, tell me what you already know and I will help you as much as possible. Please do not ask me for ideas on school research projects; part of research is determining a suitable area of investigation, and that's not a task that should be completed by someone else. Please don't simply send me your homework for solutions. If you are having difficulty after you have started an analysis, I will be happy to direct your thinking; in particular, I would prefer to not simply solve pedigrees for students, but I will be happy to assist in solving pedigrees that you have already started. If you don't understand how to analyze a pedigree, I'd highly recommend watching this video, in which a biology professor explains the basic concepts of pedigree analysis: http://www.youtube.com/watch?v=HbIHjsn5cHo
