DNA fingerprinting is a way of identifying a specific individual‚ rather than simply identifying a species or some particular trait. It is also known as genetic fingerprinting or DNA profiling. As a technology‚ it has been around since at least 1985‚ when it was announced by its inventor‚ Sir Alec Jeffreys. DNA fingerprinting is currently used both for identifying paternity or maternity and for identifying criminals or victims. There is discussion of using DNA fingerprinting as a sort of personal

FIRE RESISTANT BALLOON: Materials - 1 matchbox - 1 candle - 1 yellow colored balloon - 1 blue colored balloon - Half a cup of water Procedure: 1. For this experiment‚ the independent variable is whether the balloon is filled with water or not. The dependent variable is what happens to the balloon when it is placed above the lit candle. This is determined by observing the balloon. The constants (control variables) are how much the balloon is inflated and the amount

In Susan Griffin’s Our Secret‚ the theme that is recurring is that we are just a cog in the greater machine of society. In Our Secret Susan Griffin discovers the various characters’ fears and secrets and she gives certain knowledge into these "secrets". Through examining others Susan Griffin comes to terms with her own secrets

DNA Replication DNA replication is a biological process that occurs in all living organisms and copies their DNA. The initiation of DNA replication starts with two steps. First an initiator protein unwinds a short stretch of the DNA double helix. Then a protein called helicase attaches to and breaks apart the hydrogen bonds between the bases on the DNA strands‚ pulling apart the two strands. DNA replication starts when one double-stranded DNA molecule produces two identical copies of the molecule

DNA Extraction from Wheat Germ and Making an Agarose Gel AIM: To be able to make and agarose gel and perform gel electrophoresis in six different dyes. Also‚ to extract DNA from wheat germ. INTRODUCTION: Agarose gel is a substance that is used in science for gel electrophoresis and size exclusion chromatography. These processes use agarose gel to separate and analyze proteins and DNA. The medium is composed of a purified agarose powder that has been boiled in a buffer solution and then cooled

Scientists… The remarkable people who have shaped our world today. From inventions of the light bulb‚ to the structure of the atom. These experts have engaged in a certain field of science and excelled to come up with a numerous amount of inventions‚ and theories. Frederick Sanger followed the work on insulin and developed more in depth methods for studying the proteins structure and the centers of particular enzymes. He also assisted two other scientist in determining the amino acid sequences of

DNA REPLICATION At the replication origin DNA helicase attaches to a strand of DNA and begins to break apart hydrogen bonds in order to unravel a section of the double helix. The section of DNA that is unwound is called the replication bubble and the “Y” shaped sections are called the replication forks. In order to stop the unwound section from binding back together‚ single strand binding proteins react with the single strand portions on the DNA causing them to stay separated. Although the leading
