DNA Independent Unit
_____1.
Define the given DNA related terms in your own words. (No glossary
definitions—yuch!)
_____2.
Make a model of a strand of DNA 9 nucleotides long, with base pairs of
your choice. Must be 3-D, and needs to include 2 different types of
mutations of your choice. Some suggestions are play-doh, origami, beads,
modeling clay, etc. Label, or provide a key. Need to show this to Ms.
Brown and be able to explain it for credit.
_____3.
Extract DNA from wheat germ, or a seeded fruit. Complete the associated
worksheet with the lab. Extra credit for taking DNA home and explaining
process to family!!
_____4.
View the given link online about Meiosis and Mitosis and answer the
associated questions.
_____5.
Create a visually graphic representation of the phases of Mitosis. Be sure
to include the sub phases of Interphase (S1, G1, G2). Add a
descriptive paragraph that explains the difference between Meiosis and
Mitosis, and where in the body each of them takes place.
_____6.
Research how science defines a Hybrid animal. Using a hybrid of your
choice describe the pro’s and con’s that this animal has inherited by it’s
parents. (1 page response)
_____7.
Obtain an Onion Root Tip slide and use the microscope to identify and
sketch each of the phases seen in the cells. Be sure to use the
highest magnification, and label any parts you can identify for each phase.
Remember these are plant cells, not animal.
_____8.
Research the phenomena known as Crossing Over associated with DNA.
Explain how Crossing Over helps a society of breeding organisms keep
their genetic diversity. How does it add validity that breeding organisms
that are too closely related is detrimental to that generation? In the wild
what are 3 strategies animals use that help continue their genetic diversity
within a population?
