Molecular Biology Lab Report Mapping DNA using Restriction Enzymes Ava II and Pvu II to cut Bacterial DNA Abstract The objective of this project is to map bacterial DNA‚ which is derived from E. coli‚ using restriction endonucleases with gel electrophoresis. The DNA fragments‚ after cutting has occurred‚ are separated using agarose gel electrophoresis. The DNA fragments are placed in the gel‚ and an electric current is run through the matrix of the gel-like agarose. Migration of the fragments

AP Biology Summer Summaries There are many differences between proximate and evolutionary causes and explanations on why we are such easy targets for diseases. The proximate explanations are described by its anatomy‚ physiology‚ and biochemistry. Evolutionary explanations go into detail on what would happen if we didn’t have the genes that cause us to get sick. Proximate causes look for what genes it is made up of and how it works. Evolutionary causes are why natural selection hasn’t eliminated

An example of this is the DNA in the two cell types is precisely the same kind of DNA‚ and the genetic code for a prokaryotic cell is exactly the same genetic code used in eukaryotic cells. Other things in the two cells that may appear a difference aren’t‚ an example being prokaryotic cells have a cell wall‚ and while not all eukaryotic cells have a cell wall‚ many do including
