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.
machine code, machine language - a set of instructions coded so that the computer can use it directly without further translation. object code - the machine-language output of a compiler that is ready for execution on a particular computer. operation code, order code - the portion of a set of operation descriptions that specifies the operation to be performed; the set of operations in a computer.
