Biology 42: Lab 22 Selection & Microevolution Name ____________ Introduction: Using the Hardy-Weinberg Equation/Looking at Microevolution What are the factors that lead to evolutionary change? Using mathematical equations‚ Hardy & Weinberg in the early 20th century showed that evolutionary change – measured as changes in allele frequencies in a population from one generation to the next – will not occur unless certain kinds of “evolutionary agents” are affecting the population

Lab 6: Isolation of Chromosomal DNA Mic 428L/ Section 001 Introduction: In biological research to address and eventually answer a multitude of questions‚ usually involves isolating chromosomal DNA. The purpose in this particular lab was to isolate chromosomal DNA from mutants grown and observed in lab 5 and then digest the DNA using a restriction enzyme. The fragments left from digestion will be ligated and then transformed into a strain of E. Coli DH5αλpir containing the pir gene pi product

In the data table above‚ the mass of penny‚ copper‚ and zinc was needed in order to determine the percent composition of copper and zinc. The mass of penny was taken on the scale in the beginning of the procedure before anything was done to the penny‚ and it was 2.51 grams. After the reaction with the hydrochloric acid and drying the copper‚ the mass is 0.35 grams. To get the mass of zinc‚ the mass of the penny was subtracted by the mass of copper. The mass of zinc is 2.16 grams. The penny is 14%

Procedure: 1. The compass was placed on the lab table with no magnets nearby to identify what direction was north relative to the classroom. 2. On the ends of the variable gap magnet there were two small magnetic disks. One arm of the magnet was unscrewed and removed from its housing. A meter stick was placed on the and the arm was on its side parallel to the meter stick. The Gauss-Tesla meter was used to measure the field strength of the magnet. The probe attached to the meter was perpendicular
