The document provides the weekly lesson plans for an Advanced Biology class for the week of January 9-13, 2017. The lessons include: DNA replication and function on Monday; gene expression on Tuesday; a DNA extraction pre-lab on Wednesday; the DNA extraction lab on Thursday; and a science skills lesson on working with data in tables, DNA structure and function quiz on Friday.

1. Advanced Biology Plans for the week of January 9th
through January 13th
, 2017
o Monday 1-9-17: DNA replication and function lesson + model
o Tuesday 1-10-17: Gene Expression Lesson
o Wednesday 1-11-17: DNA Extraction Pre-Lab
o Thursday 1-12-17: DNA Extraction Lab
o Friday 1-13-17: Science Skills Lesson - Working with data in a table; DNA structure and function quiz

2. DNA structure,
replication & function

3. What do you already know about the
structure of DNA?

4. DNA REPLICATION

5. “It has not escaped our notice that the
specific pairing we have postulated
immediately suggests a possible
copying mechanism for the genetics
material.

6. Replication
= copying

7.  When DNA is copied,
the 2 strands break
apart at the hydrogen
bonds between the
nitrogen bases
 The exposed bases are
a template for the new
strand.
What are the base pairing rules?

8.  At the end of
replication
there are 2
new DNA
molecules that
are exactly the
same

9. Draw a diagram in your notebook

10.  DNA replication is
called semi-
conservative
replication
 Each new
molecule is 1/2
original DNA and
1/2 new DNA

11. Practice
 DNA strand:
ATGGCTTCTAAGGCTATC
TACCGAAGATTCCGATAG
Write the complimentary
strand
TACCGAAGATTCCGATAG

12. DNA FUNCTION

13.  DNA/chromosomes contain regions called
genes
 Genes code for proteins
 Proteins carry out life processes and give an
organism it’s physical appearance

14.  Different versions of genes are called alleles

15.  Only about 1% of the
DNA in a human are
genes that code for
proteins
 What is the other
99% for?

16.  Some DNA regulates genes
 Turns them on or off as needed
 Lots of DNA appears to have no purpose

17. DNA replication model
 Work with a partner to:
 Create a model of DNA during replication
 Clearly label the deoxyribose, phosphate, A, T, C
and G on your model
 Clearly show how some of the DNA is a coding
region called a gene and some of the DNA is
non-coding
