Context of our Teachable Tidbit Sophomore level students with introductory Chemistry and Biology background. Teaching Unit on Regulation of Gene Expression

Learning Objectives for the Tidbit

Are you: a.Female b.Male c.Prefer not to answer

Recall from previous lectures mammalian sex determination. Which of the following would lead to a male phenotype? a.XX b.XY c.XXY d.XO e.XYY

Some individuals have been found with an XX genotype, but a MALE phenotype. What could account for this? Think-Pair-Share

Sry XX:Sry Male

Using the following data, determine which phenotype would be produced by each genotype.

Sox9 Female genes Sox9 Sry and Sox9 expression

Cellular mechanism of SRY function. Kashimada K, Koopman P Development 2010;137: Teaching Gene Regulation with SRY How SRY is regulated post translational modifications translocation into nucleus other unknown mechanisms How SRY regulates other genes DNA binding protein-DNA interactions transcriptional regulation Different categories of gene regulation Strategies for gene regulation in prokaryotes and eukaryotes Evolutionary relationships based genes & gene function Placental mammals all have a similar version of SRY

Students will understand the scientific process Students will gain problem solving skills Students will be able to transfer basic principles of gene expression to a new context  Students will be able to categorize new examples into one or more of the four types of gene regulation based on presented data. Learning Objectives for the Tidbit
