The Scientific Method in Relation to Fingerprinting Although no one scientist is recognized as the inventor of the scientific method‚ its use in the scientific community believes to date back to 384-322 B.C. During this time‚ Aristotle recognized the importance of deriving reliable knowledge based on observation. As time progressed to the 1200s‚ Roger Bacon acknowledged the significance of the repeating cycle of observation‚ hypothesis‚ experimentation and verification‚ a scientific method that

is the process where non sex cells reproduce by duplicating DNA and dividing into two identical cells. Each cell has a complete set of chromosomes. These cells are called diploid (double) as they have twice as many chromosomes as the two cells that join via fetilization to form it. Meiosis is the process where sex cells (called gametes which carry the genetic material for deteriming the sex of an offspring) reproduce by duplicating DNA and diving into four new cells that have half (haploid) the

The Charge/Mass (e/m) Ratio of the Electron PHYS 0212: Introduction to Laboratory Physics Fall 2012 Abstract The experiment conducted demonstrated correlation between the charge and mass of an electron and the behavior of magnetic fields. The lab was divided into four parts. The first three parts were conducted with a compass that was used to locate the magnetic field lines around a bar magnet‚ a solenoid and then a pair of Helmholtz coils. As a result of these trials‚ our observations found

Lactate Dehydrogenase (LDH) is an cytosolic enzyme that participates in anaerobic glycolysis. LDH couples the reduction of pyruvate into lactic acid to the oxidation of NADH to NAD+‚ which allows glycolysis to continue to produce ATP in the absence of oxygen. LDH is a tetramer‚ a protein complex of 4 polypeptide subunits‚ composed either a subunit expressed strongly in the heart‚ H type‚or a subunit that is highly expressed in the muscle‚ M type. There are 5 isozymes of LDH composed the 2 subunit

against infections and catalyzing reactions. However‚ to study a certain protein it has to go through purification because cells can contain thousands of proteins. Purification allows scientist to know what molecule substrates are present‚ if the enzyme activity is regulated‚ the size‚ and what subunits are in the protein. This particular experiment focuses on lactate dehydrogenase from a beef heart. Lactate dehydrogenase (LDH) catalyzes the reaction where lactate is oxidized to pyruvate and NAD+
