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.
The highest level (as in, farthest from the computer) of a program is called the source code. Typically this is a text file written by a programmer in a formal language. Just like the informal algorithms we have discussed in class, the file would contain a sequence of instructions expressed more formally.achine code is largely the same sequence of instructions, but written in a binary code that the central processor of a computer can understand directly. As you might guess, these are very detailed instructions and they are generally not interpretable by humans.
