BISC219 F10 Weekly Lab Planner

Lab Date In-Lab Work Outside of Lab Work Assignment
1 Sept. 7 to
Sept. 13
LEARN WORM HUSBANDRY;
View worm videos;
Make your worm pick;
Examine worms: recognize different stages & sexes & differentiate mutations;
Practice picking worms;
Start Series 1: Set up autosomal and X-linked crosses
3 days after lab: pick (2) wild type worms from each cross to new plates (3 plates total);
Examine the phenotypes of the progeny – hermaphrodites and males
Homework:Complete Entry Survey; Familiarize yourself with the information in the BISC_219/F10:Resources section;
Read all of the background information on C. elegans found in BISC_219/F10:_Worm_Info and read the Lab 1 and Lab 2 information about our first Series 1: Autosomal vs. Sex-Linked Inheritance at BISC_219/F10:_Gene_Linkage & BISC_219/F10:_Lab_2; Complete Graded Assignment 1 explained at BISC_219/F10: Assignment_1_Lab1
2 Sept. 14 to
Sept 20
Complete Series 1: Count and examine phenotypes of autosomal vs. X-linked crosses;
Start Series 2: Classical (Forward) Genetics- Part 1- Perform mutant hunt:
Pick (3) putative Dpy mutants to separate plates
3 days after lab:Examine mutants from hunt: check phenotype
– if Dpy then cross L4 mutant hermaphrodites by L4 N2 males
(2 plates – duplicate)
Homework: Read ALL of Series 2 work performed in Labs 2-6 on our Classical (Forward) Genetics project and write a summary of our experimental question & goals. Outline the experimental process, including all parts of the experimental design: Mutant Hunt, Linkage Analysis, Mapping the Mutation to a chromosome and to a particular location, Complementation Analysis, Determining whether or not the mutation has been previously characterized, & Defining the gene sequence and protein change through DNA sequence analysis. Use this outline to write a 1-2 page summary of how you will determine the exact location and extent of the gene and protein change and include the significance of the mutation in worms and, if possible, broader significance in other species. Assignment explained and rubric found at BISC_219/F10: Assignment Series2_Outline_Summary
