Colorado, CHEN 1000
Excerpt: ... Fragment Polymerase Chain Reaction Restriction Enzymes Polymerase Chain Reaction Amplify millions of copies of a single piece of DNA in a few hours 3 Cutting DNA with restriction enzymes Restriction endonucleases cleave dsDNA at specific, recognized locations, generally palindromic sequences. The enzymes were discovered in E. coli bacteria in the 1970's. Illustration of endonuclease activity The EcoRI restriction enzyme recognizes the following sequence: -C-A-A-T-T-G-G-T-T-A-A-CThe complementary strand is simply the reverse sequence. 4 A few endonuclease examples www.neb.com 2. Joining DNA in new Combinations Cloning vector: DNA from source organism is cleaved with a restriction endonuclease and inserted into a plasmid DNA construct. Transformation: The resulting DNA construct is introduced into a target host cell. Selection: The cells that carry the construct are identified and grown. The protein is produced and harvested. 5 How do you get plasmids? http:/ ...

Excerpt: ... October 10th Lecture Notes: Recombinant DNA technologies continued. o Kary Mullis a method of cloning and amplifying a sequence from vanishingly small quantities of DNA or RNA accomplished using a thermostable DNA polymerase (Taq polymerase) Polymerase Chain Reaction (PCR) Denaturation step (heating the strand, breaks the hydrogen bonds) Annealing Step (cools, allows primers to anneal to the template strand) Extension step (polymerase extends the primer using free nucleotides) components of a PCR: template DNA, forward and reverse primers, free nucleotides, Taq polymerase) beginning in the third cycle, amplified sequences begin to accumulate exponentially growth drops off towards the end of 30 cycles or so.chain reaction is limited by the amount of free nucleotides and stability of the polymerase (will begin to denature after a long time) can be used to look at the evolutionary relationships between organisms.sequencing following amplification important in crime scenes.PCR can be us ...

Excerpt: ... 're a scientist and you want to study the protein x from humans. PCR copy of DNA The polymerase chain reaction (PCR) can be used to quickly copy any DNA To clone a gene you first perform PCR An enzymatic reaction what enzyme makes dna from dna? Dna polymerase Mixture exposed to cycles of heating to separate the dna strands During each cycle , dna replicates, doubling the amount 1,2,4,8, etc. After 30 cycles of PCR, yo would have over 1 million DNA that were identical to the original version. Advance uses of PCR Use it to mutate a gene Put genes back into organism, see what happens. Restriction Enzymes Enzymes are used to cut and paste dna Dna from two sources cut ny restriction enzymes at specific restriction sites Resulting restriction fragments ...

Excerpt: ... Determining Your Own Blood Type Using a Serological Test and Determining Your Rh factor by Using the Polymerase Chain Reaction Formal Lab Chelsea Aragon November 13, 2007 Biology Lab 110 B Talmadge Farringer, Marybeth Kasda, and Chris Wodiska 1 Introduction: The objective of this lab is to determine your blood type, examining a use of techniques in DNA isolation, learn the principles behind the polymerase chain reaction and compare two types of useful and practical techniques of screening tests to determine your Rh factor. There are four different blood types and two different Rh factors. The four blood types are A, B, AB, and O. The Rh factor determines whether or not your blood type is positive of negative. "Blood cells display antigens which are proteins on the surface of a cell that can be recognized by an antibody. For example Anti-A is the antibody to the A antigen and the same thing for Anti-B. The Anti-Rh negative is the antibody to the positive Rh antigen. Blood type A displays the A antigen a ...
