How CRISPR lets us edit our DNA | Jennifer Doudna

Geneticist Jennifer Doudna co-invented a groundbreaking new technology for editing genes, called CRISPR-Cas9. The tool allows scientists to make precise edits to DNA strands, which could lead to treatments for genetic diseases … but could also be used to create so-called “designer babies.” Doudna reviews how CRISPR-Cas9 works — and asks the scientific community to pause and discuss the ethics of this new tool.

How to Make a Lac Operon Using Dollar Store Items

Lac Operon

Written by Bassam El Masriitten, a 2015 Galbraith winner from the University of Ontario Institute of Technology

After teaching DNA replication and protein synthesis (transcription and translation), students are expected to be familiar with the mechanisms that control gene expression. A commonly studied example, in prokaryotes, is the Lac Operon (inducible model) and/or the Trp Operon (repressible model).

The procedure that follows outlines the steps for a teacher to build a Lac Operon model in order to demonstrate to the whole class how an operon functions. Students should be given time in class to look closely at the model themselves and manipulate it in order to better grasp the concept and be able to complete the assignment which follows.
