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.
Early languages had machine language as their object code. Many languages today such a JAVA and C# usually compile into a bytecode that is not machine code, but one that easily be interpreted at run time to produce machine code.
