EXPERIMENT OBJECTIVE: The objective of this experiment is for students to gain handson experience in the principles and practice of Polymerase Chain Reaction (PCR). BACKGROUND: Polymerase Chain Reaction (PCR)‚ discovered by Kary Mullis‚ has had an extraordinary impact on various aspects of biotechnology. PCR has revolutionized research and diagnostics-based molecular biology. PCR
Premium DNA Gene Genetics
Genetic engineering is a type of engineering where genes are modified to find cures‚ diseases‚ and more. Genetic engineering uses the central dogma‚ which is the idea of taking. DNA transcribing it into RNA translates it into protein and expressing it as a trait. Recombinant plasmids are when DNA fragments are inserted into a plasmid vector. The recognition site is where the plasmid gets cut by the restriction enzyme which is an enzyme that cuts a DNA molecule. Recombinant DNA is the DNA being inserted

Hardy Weinberg Lab I. Purpose: The Hardy Weinberg principle states that the allele and gene frequencies will stay constant from generation to generation as long as no other evolutionary influences come along. The evolutionary influences can be things such as mutation‚ mate choice‚ selection‚ genetic drift‚ gene flow‚ and meiotic drive. Frequency is the proportion of individuals in a certain category relative to the total number of individuals considered. The frequency of an allele or genotype is

Selection Simulation Lesson 2 (as modified from Robert Gendron’s “Simulating Natural Selection” for Introductory Biology Lab College Course‚ Indiana University of Pennsylvania) Key Question(s): What is natural selection? How does natural selection change allele frequencies over time? Does natural selection work differently on large versus small populations? What is genetic drift?

In the following experiments on gene pool‚ gene frequency‚ and genetic diversity; assume there are four alleles for color and that they are all homologous. Experiment 1: Genetic Variation Genetic variation is simply the genetic difference within or between populations‚ in the gene pool and/or gene frequency. Consider the following two populations of butterflies (Figure 2): Figure 2: Butterfly populations. Assumptions: Both populations contain the same four colors of butterflies‚ thus the gene pool

rely on the filter number 609 of the E.E.L reflectometer to determine different skin colours (Relethford‚ p 17). Population geneticists tend to use the degree of variation among populations using a measure known as Wright’s FST. FST can be estimated from phenotypic traits given heritability estimates (Relethford et al. p‚ 17). Regardless of whether one considers the FST values from genetic markers useful or not‚ when it
