Represents the entire Microsoft Excel application. The Application object contains: Application-wide settings and options (many of the options in the Options dialog box (Tools menu), for example). Methods that return top-level objects, such as ActiveCell, ActiveSheet, and so on.
Proteins consist of one or more of these polypeptide chains. The primary structure of a protein is known as a polypeptide. From the two terminals of the polypeptide chain, N-terminus is where the amino group is free, and the c-terminus is where the carboxyl group is free. Polypeptides are synthesized at ribosomes.The amino acid sequence in the polypeptide chain is determined by the codons in mRNA. Protein.

When the information is to be used to produce a polypeptide, the RNA is known as a messenger RNA or mRNA. The information in the mRNA will then be translated from a nucleotide into a polypeptide sequence. This process involves a large macromolecular complex, the ribosome, and various accessory factors. The sequence of nucleotides in DNA is related to the final sequence of the polypeptide by the genetic code. The genetic code is not the information itself, but the algorithm by which nucleotide sequences encode polypeptide sequences.
