five-kingdom system. New advances in genetic and molecular sciences have allowed for classification based on information such as base composition‚ nucleic acid hybridization‚ and amino acid sequences. The two main molecular methods to identify microbes are by the comparison of 1) DNA and RNA sequences (nucleic acid hybridization) and 2) of amino acid sequences of a protein or proteins (amino acid sequences). Nucleic acid hybridization‚ a part of the field molecular genetics‚ is used to identify related DNA

------------------------------------------------- Enzyme Pre-Lab Harry Kang 9/26/12 1) The purpose of this lab was to determine the rate of enzyme activity under variety of different conditions‚ such as‚ different amount of drops of enzymes and different temperature of water. The class measured the pressure in the test tube during the reaction of the substance with‚ 1.5 ml of H2O2‚ 1.5ml of H2O and different amounts of enzyme drops‚ to determine how much oxygen gas is produced during the reaction

. Information transfer is fundamental to all living organisms. For the three following examples‚ explain in detail how the transfer of information is accomplished. a. The genetic material in one eukaryotic cell is copied and distributed to two daughter cells. Eukaryotic cells go through Interphase and Mitosis. Interphase is further subdivided into 3 stages‚ G1 (first gap)‚ S (synthesis of DNA)‚ and G2 (second gap). In all 3 sub phases cell growth happens and organelles like mitochondria are replicated

AP Biology Outline for Behavior Territoriality - behavior of animals that enables individuals to occupy and dominate an area. Territory is an area where one or more individuals defend the area. Thus the two are interpedently interacting with each other to defend the area. Dominance Hierarchies social organizations in which some individuals of the group have adopted a subordinate status to others. The role of this in social behavior is that it shows that the subordinate individuals are depended

structure of something you didn’t even know existed‚ what you are imagining is James Watson. Watson changed molecular biology in amazing ways that changed science forever. He discovered the structure of DNA. James Watson had an extremely influential life. His main discovery was the structure of DNA‚ but he also discovered the helical construction of tobacco mosaic virus. The discovery of the molecular structure of DNA was a ginormous scientific breakthrough. Watsons current research includes the role of

Association for Molecular Pathology vs. Myriad Genetics The case of the Association for Molecular Pathology vs. Myriad Genetics was a case that challenged the validity of gene patents in the United States. It specifically challenged certain claims in issued patents owned or controlled by Myriad Genetics that cover isolated DNA sequences‚ methods to diagnose propensity to cancer by looking for mutated DNA sequences‚ and methods to identify drugs using isolated DNA sequences. Before this case occurred

AP Biology Photosynthesis Lab Bethany Boyer Due 11/12/14 Lab Write-Up Questions First Experiment 1) The independent variable in this experiment was the presence of CO2 (carbon dioxide). The dependent variable was the speed at which the leaf disks started to float. 2) In the leaf tissue‚ the bicarbonate and light are combining to carry out photosynthesis. This will cause oxygen to collect in the leaf tissue‚ causing it to rise. 3) If we were to boil the leaf disks‚ the reaction would most likely

Sporophylls and Spore Variations – Led to flowers in angiosperms‚ which increased genetic variation in plants. 13. Distinguish between microphylls and megaphylls. a. Microphylls are small‚ single veined leaves. Megaphylls are larger leaves with a highly branched vascular system. The vascular system allows the leave to grow wider because
