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.
5.2.1. A machine language is a set of binary codes which is used to direct the activities of a Central Processing Unit (CPU). Everything a computer does is the result of running machine language programs. No matter what language you use to program, the computer hardware is ultimately running machine language in order to execute your program. Individual codes in the machine language are known as instructions. Hence, a machine language is also known as an instruction set.
