the structure of DNA they wanted to use the information to help them identify how DNA is replicated. Three different theories of replication were proposed by Watson and Crick. The semi-conservative model‚ where the DNA strand splits into two halves‚ which will then create a new DNA strand consisting of the old original half and a new half. The conservative model where the whole of the original DNA strand acts as a template and is replicated to make a completely new strand of DNA. The dispersive model

Paper Cone Investigation Lisa Han 10MF Design Research Question: This investigation will determine how the sector sizes of the piece of the filter paper affect the terminal velocity for the cone to fall. The following will be kept constant meter ruler‚ stopwatch‚ and filter paper. Hypothesis: ‘If the sector size is the increase‚ then the terminal velocity will decrease.’ The reason is that if the sector size is bigger‚ the surface area of the cone will become smaller. If the surface area

DNA is the most important for life One of the most complex and mysterious aspects of contemporary science is the constitution of life. While it goes without saying there are an enormous amount of components that collaborate to achieve the most effective and efficient components of life‚ it’s also clear that some of these molecular components contribute to the actual function of living system more than others. This essay argues the DNA is the most important molecule for life. Deoxyribonucleic

for the DNA ligation‚ in which the gene products with sticky ends will be inserted to a plasmid vector. Also‚ to transform E.coli DH5α cells by introducing the plasmids DNA which contains the gene of interests into the E.coli strain(DH5α). The plasmid DNA can replicate inside the transformed E.coli DH5α cells‚ only successful transformed cells can produce the protein that is resistance to kanamycin‚ this allows for the selection of successful transformed cells. 2. Overview of experiments DNA purification

So now that we know what recombinant DNA is‚ we are going to look at its purposes. ******** Recombinant DNA is used to insert a gene for production of a protein of interest The production of heat and drought resistant crops can alleviate world hunger around the world. Production of clotting factors can treat bleeding disorders such a Haemophilia which casues bleeding into the joints and can be life threatening. Hepatitis B vaccines are made with the help of yeast cells It is used for the production

Criminal Profiling The term “serial killer” was derived from a man named Robert K. Ressler‚ who‚ in the 1970’s deemed this term because of the term the English used; “crimes in a series” and because of the serial films he grew up watching. (Freeman‚ 2007) Prior to the term serial killer‚ people would use the terms‚ mass murders and stranger-on-stranger crime. The definition of a serial killer‚ according to dictionary.com is; “a person who attacks and kills victims one by one in a series

7.1.1 Describe the structure of DNA‚ including the antiparallel strands‚ 3’-5’ linkages and hydrogen bonding between purines and pyrimidines. DNA is made up of two strands. At one end of each strand there is a phosphate group attached to the carbon atom number 5 of the deoxyribose (this indicates the 5’ terminal) and at the other end of each strand is a hydroxyl group attached to the carbon atom number 3 of the deoxyribose (this indicates the 3’ terminal). The strands run in opposite directions

this lab was to isolate DNA from a food sample‚ amplify the DNA using a polymerase chain reaction‚ and test the amplified DNA for the presence of the Bt gene or the 35s promoter. In part one of DNA isolation‚ the food sample was crushed before Lysis Buffer was added‚ in part to break down some cell walls‚ but also to increase area of the food sample being touched by the Lysis Buffer. The purpose of Lysis Buffer is to break down the cells in the food sample and release their DNA into the solution. By
