terms of clusters of interacting residues and the identification of highly connected residues (hubs) along the protein–DNA interface. A predominance of deoxyribose–amino acid clusters in b-sheet proteins‚ distinction of the interface clusters in helix–turn–helix‚ and the zipper-type proteins would not have been possible by conventional pairwise interaction analysis. Additionally‚ we propose a potential classification scheme for a set of protein–DNA complexes on the basis of the protein–DNA interface

She gave quantitative details about the shape and size of the double helix. The all- important missing piece of the puzzle that she could not discover from her data was how the bases paired on the inside of the

Section 1 : Identifying the Genetic Material Griffith’s Experiments In 1928‚ Frederick Griffith‚ a bacteriologist‚ was trying to prepare a vaccine against pneumonia. A vaccine is a substance that is prepared from killed or weakened disease-causing agents‚ including certain bacteria. The vaccine is introduced into the body to protect the body against future infections by the disease-causing agent. Griffith discovered that harmless bacteria could turn virulent when mixed with bacteria that cause

amino acids‚ can harm your muscle fibres‚ leading to diseases such as Duchenne muscular dystrophy‚ where the muscles weaken and begin to waste away. Secondary Structure The secondary structure is the folding of the amino acid chains into an alpha-helix or a beta-pleated sheet. It is determined by the sequence of amino acids in the primary structure. The polypeptides within the secondary structure are held together by many hydrogen bonds‚ which give the structure great

third examine how meiosis allows DNA to be divided into gametes and finally‚ describe how this relates to Gregor Mendel’s patterns of inheritance. The structure of DNA DNA is a thread formed by two strands‚ related together to form a Double Helix. The Double Helix looks like a twisted ladder. The "sides" of this "ladder" are long units called nucleotides and are made of three parts; a nitrogenous base‚ a sugar‚ and a phosphate group. The sides of the ladder or the nucleotides from the two separate strands

KEY: ABE Lab 1: Prelab: Page A17‚ Questions 1 and 2: 1. What does the term genetic disease mean? What examples of generic diseases do you know about? A genetic disease is a disease caused by an absent of defective gene in the DNA. Students may know of sickle cell anemia‚ which is a disease resulting from defective red blood cells; treatment of sickle cell anemia focuses primarily on relieving pain and controlling infections and other complications that may occur. 2.
