DNA – RNA Notes The sugar in DNA is called deoxyribose. The sugar in RNA is called ribose. -RNA is a single strand of nucleotides. DNA is made of two strands of nucleotides. -DNA is a double helix with hydrogen bonds linking the nitrogen bases. RNA is a linear strand with no hydrogen bonds. -The bases of DNA are: Adenine‚ Thymine‚ Cytosine‚ and Guanine. The bases of RNA are: Adenine‚ Uracil‚ Cytosine‚ and Guanine. -RNA does not have Thymine‚ and DNA does not have Uracil. -In DNA

DNA and Crime Deoxyribonucleic Acid - the fingerprint of life also know as DNA was first mapped out in the early 1950’s by British biophysicist‚ Francis Harry Compton Crick and American biochemist James Dewey Watson. They determined the three-dimensional structure of DNA‚ the substance that passes on the genetic characteristics from one generation to the next. DNA is found in the chromosomes in the nucleus of a cell. "Every family line has it’s own unique pattern of restriction-enzyme DNA

Fingerprints can give a lot of information about an individual. Every fingerprint is unique to that person‚ therefore it is a great resource for police to help locate people involved in a case. Families share many of the same traits in their DNA but people are unsure of whether or not they have similarities‚ In this experiment that question will be answered. There are three main fingerprint types: arches‚loops‚and whorls. (GeneEd - DNA Fingerprints 2003‚ April 12). The police take fingerprint

½Give an account of the structure and properties of Biological membranes. Include details of the modifications of membrane structure found in different specialised cells and organelles½ The Fluid Mosaic model was codified by Singer and Nicolson in 1972. It describes the structure and properties of the cell membrane very simply. Every membrane consists of a Phospholipid bilayer. This is simply two layers of phospholipid molecules that come together due to their unique properties. The heads of the phospholipids
