DNA Electrophoresis (Lab Report Sample)

TITLE: Lab Report on DNA Electrophoresis STUDENT NAME: DATE OF SUBMISSION: Procedure I - DNA Fragment Size We performed DNA electrophoresis to analyze the sizes of DNA fragments in various samples. Gel electrophoresis separated these fragments based on their sizes. The results indicated that Sample 1 (Lane 1) contains the smallest DNA fragment, while Sample 2 (Lane 2) contains the largest. Procedure II - Crime Scene DNA We compared DNA fragments from different samples, including a crime scene sample, to determine which samples had DNA fragments in common with the crime scene. The crime scene sample (Lane 2) shared three DNA bands with the student's sample (Lane 1), suggesting a potential connection between the student and the crime scene. Procedure III - Paternity Case Procedure III involved analyzing DNA fragments to establish paternity in a calf. The calf (Lane 2) had three common DNA bands with both its mother (Lane 1) and a male (Lane 3), indicating genetic inheritance from both parents. Further analysis with a probe and filter confirmed the calf's genetic similarity to the male (Lane 3). Procedure IV - Species DNA Comparison The DNA sequence determined in Procedure IV was "TCAGCGTCACTAACGT." The percent alignment calculations for known pla...
