DNA, it makes everyone special and unique. Throughout time, scientists have discovered many things about DNA. One such discovery the pairing of adenine-thymine and guanine-cytosine, but what about the structure? Watson and Crick are acknowledged the most for discovering and contributing the most to the structure of DNA in eighteen months; but what about Franklin? Though Watson and Crick are known for discovering DNA’s structure, Rosalind Franklin contributed the most to finding the structure of…

called nuclear DNA) but a small amount of DNA can also be found in the mitochondria (where it is called Mitochondria DNA or mtDNA). The information in DNA is stored as a code made up of four chemical bases: Adenine (A), guanine (G), cystoine (C) and Thymine (T). Human DNA consist of about 3 billion bases and more then 99 percent of those bases are the same in all people. the order ,or sequence, of these bases determines the information…

Cell Biology Beta cells in pancreatic tissues are described as eukaryotic cells and not prokaryotic, this is because the cell is larger in size and there is a true nucleus present which contains DNA. In prokaryotic cell there isn’t a nucleus and the DNA is free within the cytoplasm. Also Beta cells have many organelles and there is mitochondria present, which in a prokaryotic cell there are fewer organelles and there aren’t any mitochondria present. Beta cells in the pancreatic tissue release…

DNA is the part in all human’s bodies that make people who they are. Every one in the world has their own DNA unless that person has an identical twin. DNA is working in every persons' body each day. This research paper will explore how DNA affects everyone’s life. What DNA is, the structure of each DNA molecule, some interesting facts about DNA, and what a gene is will be addressed in this document. Many people wonder what make each person special. Well, that question is answered with the…

bound together. Nucleotides contain a deoxyribose sugar, a phosphate group, and one of four nitrogenous bases. The four nitrogenous bases are adenine (A), thymine (T), guanine (G), and cytosine (C). To construct DNA’s double helix, hydrogen bonds form between two complementary nitrogenous bases. These bonds only form between adenine and thymine and between guanine and cytosine (“DNA”). DNA contains the instructions on how to create and build an organism. A gene is a sequence of nucleotides that…

Carbohydrates, lipids, proteins and nucleic acids are large biological molecules that play a major role in relation to the structure and function in plants and animals. These organic molecules consist of many examples and functions. Each biological molecule has a unique function and emergent properties that helps contribute to the cellular structure in both plants and animals. These biological molecules are known as macromolecules because they are large and are composed of thousands of atoms.…

Proteins Proteins are large, complex macromolecules that play many important roles in organisms. They are required for the regulation, structure, and function of the body’s organs and tissues. Some may act as antibodies, chemical messengers, enzymes, structural components, and transport devices within the cell. Proteins are made up of hundreds or thousands of smaller subunits known as amino acids. Amino acids are made up of a single carbon atom attached to a carboxyl group, an amino group, and a…

supported the keto form. This form allowed Watson to experiment more with the bonding between the bases to see which way the bases would fit together in order to form the correct width of the molecule. Watson eventually ended up pairing adenine with thymine and cytosine with guanine, and Donohue checked this theory to confirm that these pairings made sense chemically. Without Donohue’s chemical knowledge, the discovery of DNA structure might have been greatly delayed. A great amount of careful…

World War II is coming to an end and the race begins to discovered the structure of DNA. It’s May 1st, 1952 in a London lab an x-ray camera is clicking off 100 hour exposure of something called DNA. When developed this photo will show the structure of DNA. This photo will explain the blueprint of all life, and how DNA is passed on from generation to generation. Francis Crick and an american scientist James Watson will be in the race for discovery of the century, along with 31 year old British…

Normally in DNA replication, there are certain bases that are paired together. Adenine is paired with Thymine, and Cytosine is paired with Guanine. If any of these bases happen to match with an incorrect base, this is considered a genetic mutation, and can cause great harm to the DNA replication process. When this happens, repair proteins such as PMS2, MLH1…
