    How the structure of proteins are related to their functions Rachel Morris The basic building blocks of proteins are amino acids‚ the biuret reaction tests for protein. A solution of sodium hydroxide is added to a sample then a few drops of copper sulphate solution‚ if positive – the solution will turn mauve. There are 20 different amino acids and they can be joined in any order. Therefore there can be many different functions. A protein consists of one or more polypeptide chains (a polypeptide

    Exercise 13 MITOSIS: REPLICATION OF EUKARYOTIC CELLS ANSWERS TO QUESTIONS 1. a. Mitosis and cytokinesis are often referred to collectively as "cellular division." Why are they more accurately called cellular replication? The result of mitosis is production of two cells (replicates) identical to the parent cell. The genetic material is replicated rather than divided. b. Does the cell cycle have a beginning and an end? The organization of our study of cellular events indicates a beginning and

    “The structures of body systems are determined by their functions”. Discuss this statement‚ focussing on the Circulatory System. You should include diagrams and relevant examples in your essay. In order to survive it is necessary for every cell in the body to exchange materials as not all cells are in contact with the external environment; we rely on the circulatory system to do this which is composed of the heart‚ blood vessels and blood. The heart consists of four chambers two atria and two ventricles

    Cells are the basic functional units of all organisms. Cells are the smallest unit of life and are often called the "building blocks of life". The distinction between prokaryotes and eukaryotes is considered to be the most important variation among groups of organisms. Eukaryotic cells contain membrane-bound organelles‚ such as the nucleus‚ while prokaryotic cells do not. The differences in cellular structure of prokaryotes and eukaryotes include the presence of mitochondria and chloroplasts‚ the

    Prokaryotic vs. Eukaryotic cells have similarities and differences. They can be found in different places. They have different ways of functioning and can be made up of different things. But just how they are very different they have some similarities that can in a way unite them and make them a part of the of a cell family. With their differences and similarities‚ they’re just here for one solemnly purpose‚ to serve whatever type of organism they are present in. A Prokaryotic cell does not have a
