Monday tutorial-T53

Hi T53 people,

1) I will post a quick summary of "what you need to remember/understand" from week 2 (this week)-it will be up for sure by Sunday evening.

2) Please bring to Monday's tutorial a copy of Dr. Beatty's problem set 2. We'll work on it and we'll systematically construct (together) a list of tricks and rules to use to interpret and solve operon kinds of questions.

The main concepts of Monday's tutorial (subject to change):

- cis-acting vs. trans acting and what we can use this for

- positive vs. negative regulation, and how we can tell which one is at work

- some details and oddities of the lac operon

- some very successful ways to lose marks on an operon exam question!

Cheers

Pam
