The two main types of nucleic acids are deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). DNA is the genetic material found in all living organisms and is found in the nucleus of eukaryotes and in the chloroplasts and mitochondria. In prokaryotes, the DNA is not enclosed in a membranous envelope.
A program written in a compiled language is first translated to machine language by another program called a compiler. The compiler parses each statement in the program and outputs an equivalent sequence of machine or assembly instructions.
It only understands on and off. So to actually run a command like print 'Hello, world!', it has to translate all the code in a program into a series of ons and offs that it can understand. To do that, a number of things happen: The source code is translated into assembly language. The assembly code is translated into machine language.
