Protein Essay

A protein is a macromolecule found in cells. A macromolecule is made up smaller molecules. Similarly, a protein is made of up of many smaller molecules called amino acids. Inside of a living cell. Proteins are built in the ribosome, an organelle inside of a cell. Many structures such as tissues and organs are made of proteins. They are the main components of hair, skin, muscle, heat and other important organs. Many important part of a living organism depend on these to proteins to function properly. For example, athletes are often recommended to eat foods high in protein for muscle development. Proteins also carry many functions that allow communication of different parts of a human body. They can act as enzymes to accelerating reactions in the body that …show more content…
A phenotype is a trait that is visible in an organism such as eye color and height. This indeed led to so many observable characteristics seen in an organism. Information encoded in the DNA inside of nucleus of living cell must go though many stages: DNA~RNA~Protein with various other steps before the final product. A copy of the DNA facilitates information in genes to become available for protein synthesis. Pre-mRNA is the first sequence and then messenger-RNA is the final step before protein. Different parts of the sequence is removed through a process called splicing. Some parts of the Pre-mRNA called are introns are removed, and different pieces called exons are sew together for translation. In the past, introns were considered as pieces without any function in the cells. And one gene gives rise to one protein, but now it is believe different proteins can emerge from a single gene. Knitting the exons in different ways can give rise to different proteins. Gene expression is the process by which information in a gene is converted to a protein. This process involves in direct flow of information from DNA to RNA and then
