Wales and Michael Snow. | [Hide] [Help us with translations!] | DNA vaccine What is antisense technology? Antisense refers to opposing the normal order (“sense”) of the code in DNA. The DNA (deoxyribonucleic acid) in genes directs cells to assemble the proteins which comprise living creatures. The order of bases in DNA corresponds to the ordering of amino acids to form the proteins. To produce protein‚ the DNA of the genes in cells is first transcribed into a very similar molecule called RNA.

17.1 Genes specify proteins via transcription and translation * George Beadle and Edward Tatum worked together with mutated (Neurospora crass) bread mold to figure out that they were missing a specific enzyme (gene) that catalyzed and synthesized a pathway required. They concluded that they were missing that enzyme because it was lacking the amino acid that coded for the enzyme‚ thus was mutated and incapable of growing. Led to the one enzyme-one gene hypothesis. The Products of Gene Expression:

DNA Cloning PCB3063L Section DNA cloning refers to the process of making multiple copies of a DNA fragment. For the past weeks we have conducted a set of experiments that allow us to clone a specific gene in drosophila. First we started by the process of DNA extraction‚ which allowed us to isolate the genomic DNA from D. Melanogaster. This process requires the use of lysis in other to extract the DNA and RNA. After extracting the DNA‚ we it is important to use

Unit 2 Lecture Study Guide – 1) What are the parts of an atom? Where are the subatomic particles found? a) Protons‚ neutrons‚ and electrons b) Protons and neutrons are located in the center of an atom in the nucleus and the electrons are located around the nucleus. 2) How does the Atomic Mass # differ from the Atomic #? The atomic mass number is the sum of the number of protons and neutrons in the nucleus of an element and the atomic number is the number of protons that it has. 3)
