PLASMID DNA ISOLATION‚ RESTRICTION ENZUME DISGESTION AND AGAROSE GEL ELECTRIPHORESIS Abstract: The gel is covered with an ion- containing buffer‚ such as (TAE)‚ that controls the pH of the system and conducts electricity. overall DNA concentration was lower than expected. Using agarose gel electrophoresis is to separate and visualize the DNA fragment‚ which is produced by restriction enzymes . Introduction: The purpose of this experiment is to measure the size of the fragments of DNA and separate

One of the reasons for this is the confusion that often arises from using a tree model to describe a phylogeny (Baum‚ 2008a). Many people interpret

public‚ and the scale has experienced multiple changes since the first day. The question is‚ do IQ-test really measures person’s intelligence? According to Howard Gardner’s article “Human Intelligence Isn’t What We Think It Is”‚ humans are multi-intelligence beings. So‚ IQ-test merely cannot provide an accurate representation of an individual’s intelligence level‚ rather IQ-tests generally measure only two forms of intelligence which are linguistic and logical-mathematical intelligences. However‚ we

DNA replication mechanism is an integral and the most important part of cell division. It is a complicated mechanism that requires a lot of steps and different enzymes. Many scientists were trying to understand the mechanism of DNA replication and its role in the transfer of the hereditary information to the offsprings. DNA replication begins with a single origin of replication that starts off the process by creating a replication bubble. In many eukaryotic cells‚ the DNA strand will have more than

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

Experiment 2 Quantification of Proteins in Solution by Spectrophotometer Lab bench# 1 Introduction: Absorption spectroscopy is a common method for finding the concentration of proteins or protein complexes in a solution. Proteins absorb light at specific wavelengths and can be defined by the equation A = log (Io/I). This equation states that an absorbance at a specific wavelength‚ A is equal to the log of the ratio of incident light intensity (Io)‚ to transmitted light intensity (I). A

Although there are many different types of methods used to analyze DNA‚ the general process is based upon the uniqueness of each individual’s DNA‚ much like a fingerprint. Due to this uniqueness‚ genetic evidence that matches a specific individual to a crime scene is often viewed as concrete and undeniable
