Lab RepoRt assistant This document is not meant to be a substitute for a formal laboratory report. The Lab Report Assistant is simply a summary of the experiment’s questions, diagrams if needed, and data tables that should be addressed in a formal lab report. The intent is to facilitate student’s writing of lab reports by providing this information in an editable file which can be sent to an instructor. Exercise 1: Modeling DNA The students must attach the DNA model to this lab report. Note which nucleotides form pairs—cytosine and guanine, and adenine and thymine form pairs. Questions†¦show more content†¦Did the new DNA model form any two of the same amino acids? Yes it seemed the AGC and AGU both formed the new amino acid Serine. G. Optional: Compare the amino acids that were formed in this experiment with those of classmates who also performed this experiment. Were there many similarities? Pre-lab for Cell Reproduction What is a cell cycle? The activities that occur within a cell cycle from the end of one cell division to the end of another. What occurs in each phase below: a. GI – A cell and its organelles double in size. It’s a growth phase. b. S – Strands of dna within a chromosome separate from each other and complimentary strands are made. c. G2- In animal cells the centrioles divide and migrate to the opposite poles of the nucleus. In both animal and plants the proteins are synthesized and spindle fibers become assembled which later attach to chromosomes and aid the migration for cell division. d. Mitosis- The cell actively divides. Define the following terms: a. Chromosome – Threadlike bodies that carry genes in linear order b. Chromatid – The new DNA molecules c. Centromere- The structure that holds together the new DNA molecules d. Helix- spiral polymer of nucleic acids. When studying the onion root tip slide, where will you focus to find the most dividing cells?

To show this, we are using tobacco seeds, a monohybrid cross comparing only one trait color. We are also showing Mendel’s law of segregation with a Dihybrid cross comparing two traits of color and texture.

These conditions, such as introducing a flame to the gas as well as oxygen and CO2, caused other reactions to occur. Hypothesis: If the gasses are correctly synthesized then there will be a clear reaction with the introduction of the flame, O2, CO2, AirRead MoreLabpaq Lab Techniques and Measurements Essay1512 Words   |  7 PagesTitle: Observations of Chemical Changes Purpose: To learn about the international system of units (SI), to become familiar with common lab equipment and techniques, to gain proficiency in determining volume, mass, length, and temperature of a variety of items using common laboratory measurement devices, to learn to combine units to determine density and concentration, and to use laboratory equipment to create serial dilutions and determine the density and concentration of each dilution.
