Slime Mold, Restaurant inspections and Test in your first biology 11 block next week

Tuesday and Wednesday, Jan 31, Feb 1

Review these note packages for our test protozoa notes    and the Introduction to Microbiology Notes
You ought to be familiar with all examples. 

Today we looked at slime mold and also listened to a Quirksand Quarks episode on slime mold that can learn

Today we went over microbiology- kingdom Monera and we looked at the Vancouver coastal health inspection reports.   plus we sampled bacteria to grow on petri dishes.  We will not handle these bacteria, only superficially observe the first few colonies that emerge.

Make a cartoon of the trp operon and compare it with the LAC operon

Intro to Protozoa

Review these protozoa notes and use the review package to answer questions

Viruses and Monerans

Note that the evolution retest will take place next block
Today you will go over the Introduction to Microbiology Notes, which cover Virus, and Monerans, with a mention of unicellular fungi.  We will likely only have time to review the lytic and lysogenic cycle today.

You can also continue with your notes on microbiology.  

STEPS TO THE LYTIC CYLE: memorize AESAR

• Attachment
• Entry & degradation of host's DNA
• Synthesis of new viruses 
• duplication of virus' genetic material
• creation of new virus parts
• Assembly of parts into new viruses
• Release of new viruses

 steps to the lysogenic cycle:  memorize AEIM

• Attachment
• Entry (no degradation of host DNA)
• Integration using integrase enzyme
• Mitosis
• Host+virus DNA duplicated
• cytokinesis
• A virus that uses the lysogenic life cycle is termed either a provirus or prophage. What causes various proviruses to shift to the lytic cycle is not completely understood, but in some cases stress is the stimulus.

test on evolution Jan 9, 10

Evolution
How evolutionary change occurs
Slideshow: Geological Time also images from a discussion on
punctuated equilibrium
natural selection

Evolution Review for the upcoming test!

You will create two column notes after we review key concepts on
Evolution
Natural Selection
Punctuated Equilibrium

Test is scheduled for Mon/Tue Jan 9/10
