Today we started DNA structure and replication.   We took notes from the Power Point slides and then extracted the DNA from strawberries. 

You should have turned your lab in and then completed the Module Questions- Section A on DNA structure.

Today we did lab 2E on page 30.   Law of Definite Composition.   This formal lab write up will be due Monday include all Questions and Follow up Questions.

We wrote the Biomolecules and Cells Test Today.

We start DNA replication on Thursday so read the first section of Chapter 25 to prepare for Class as well as the extracting DNA from strawberries lab.

Today we got back lots of work on naming compounds and writing formulas for compounds.  Make sure you know how to name and write formulas for ionic and covalent compounds and for acids. 

We got the Unit 2 Test Review which will be due on Tuesday Feb. 28th.  Also the date of the Unit 2 Test.

Tomorrow we will do Lab 2E so make sure that you have your lab set up ready to go for tomorrow.

Today we did the last part of naming.   We named and wrote formulas for Covalent Compounds and Acids.   Practice worksheet with a partner on this.

Hebden practice:  page 76 Ex: 80-87 and Ex: 133-139

Today we reviewed for our test tomorrow on Biomolecules and Cell Organelles.

We watched a Crash Course in Biology Video to review biomolecules.  

Then for Test Practice on Big Paper (like a flash card) Draw structure on the front and then on the back write some things about this molecule:  what is it used for and what organelles use this or make this?

Carbohydrates:
1) Glucose (monosaccaride)     2) Sucrose (disaccaride)
3) Starch (polysaccaride)     4)Gylycogen

Remember that cellulose is an unbranched chain of glucose found in plant cell walls

Lipids:
1)Neutral Fats (triglycerides)            2) Cholesterol         3) Phospholipids
Draw monomers that make this up

Proteins:
1) Amino acid (monomer)      2) Show a primary structure of a protein with polypeptide bond.

Nucleic Acids:
1) Nucleotide
Draw and label phosphate, sugar and a base

2) Draw ATP
