Wednesday April 8th - Point Mutations

REMINDERS!!!!

EXAM on FRIDAY (There is a practice test available on study island now!!)

TRANSCRIPTION/TRANSLATION Webquest journal due FRIDAY

Yesterday we focused on frameshift mutations.  Today we again used the daily question time to learn more about mutations.  I flipped between the slide show, your study guide and the daily questions themselves.

Here are some pictures of my intro about POINT mutations.

Then to the first couple daily questions:

Here is a podcast of my discussion of point mutations and the first set of daily questions:

We finished up with at a QUICK look at chromosomal mutations:

Then to our Module A keystone questions.

The first question was VERY tough.  The wording is easy to get caught up on and I am the first to admit I fell RIGHT into the trap that I warn you guys about.  Technically answer A is correct - but now the MOST correct.  We DID learn that Water has a high specific heat.  MEANING that it takes a LOT of energy to increase or decrease the temperature.  This is why coastal regions tend to have very moderate (not necessarily warmer) temperatures (because it will stay cooler longer in the winter and warmer longer in the summer)

BUT......  The correct answer was ACTUALLY "C" - when we sweat water turns into a vapor which absorbs heat (from us) allowing us to cool down!!  That was a toughie for sure - but the BIG ideas I want you to walk away with is the fact that water has a high specific heat!!

The second question was pretty straight forward and allowed me to have a nice review of the cell membrane with you!!
