The Five Major Structures of the Brain The brain is an amazing structure. It is the most complex and interesting part of the human body. It is like a huge computer that runs every function of the body. The brain is made up of the five major structures that include: the myelencephalon‚ metencephalon‚ mesencephalon‚ deicephalon‚ and the telencephalon. Each of these structures also has substructures involved within them. You start learning how to do things when you are born and keep learning as

The race to find the structure of DNA was on. James Watson and Francis Crick model builders were working on finding out the structure of DNA first. I Rosalind Franklin a crystallographer am also working on finding the structure of DNA. But before I could officially identify the structure of DNA‚ Watson and Crick were successful. Now James Watson is writing a book about DNA‚ and I am told to give some feedback about it. I will be telling you about what I think about James Watson’s book‚ The Double

DNA‚ or deoxyribonucleic acid‚ is the hereditary material in humans and almost all other organisms. Nearly every cell in a person’s body has the same DNA. Most DNA is located in the cell nucleus (where it is called nuclear DNA)‚ but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA). The information in DNA is stored as a code made up of four chemical bases: adenine (A)‚ guanine (G)‚ cytosine (C)‚ and thymine (T). The order‚ or sequence‚ of

I. Describe the structure and function of the nucleus and mitochondria. The mitochondria is a semi-autonomous organelle which reproduces by bynary fission and has its own DNA. Its main function is to produce the energy intermediate ATP‚ through ATP synthase. Mitochondria could be considered a cell inside a cell. It has its own membranes (inner and outer membranes)‚ its ribosomes (to produce the proteins encoded in its DNA)‚ a matrix -- where aerobic respiration occurs. The invaginations of the inner

DNA Assignment Keshia Yeates BIOLOGY 4U 1. DNA molecule with a length of 2m can fit inside a nucleus that is invisible by the naked eye by coiling around itself several times. It continues to coil even more (Supercoiling)‚ arranging itself on histones‚ which are proteins. 2. Nitrogen bases determine the traits of living organisms by coding the 20 amino acids. The order of the amino acids determines what protein is made; therefore‚ proteins are the makeup of all living organisms. Proteins regulate

the concept of “discovery”? Discovery can have a different impact on different individuals. The composer ”Oodgeroo Noonuccal” reflects on her discovery of the” old native burial ground” as a spiritual journey‚ rather than an intellectual journey experienced by the scientists and the modern world. Discovery can offer us a positive or negative experience. Oodgeroo Noonuccal felt strongly reverential towards the old one and the past‚ but she was more disdainful towards the scientist and the modern
