Understanding DNA: How Stuff Works


DNA BASE PAIRS


GeneticVariation:A Key to Survival


GENETIC VARIATION

leads to

Adaptation


RESISTANT STRAIN

Different copy

Identical copy


Mixing of Genes

CROSSING OVER


MINI-LAB: Observing cell reproduction

  • Mount a prepared slide of a cell undergoing cell division.

    2. Draw the cell and label the ff structures: a. cell membrane b. chromosomes

    3. Describe what you see.

  • Note: Follow guidelines on

  • Making Diagrams

  • Accurate representation

  • 2-D diagram

  • Proper labels

  • Neatly presented


Crossing over: Why we are different from our parents

VC; Where do genes come from


From Geneto Protein: An exercise in breaking the code


DNA COPIES ITSELF:Base pairings: A- T C – GDNA moleculeunzips breaking the base pairs forming 2 sides

VC: DNA Replication


A: TACCGGATGCCAGATCAAATCWhat is the other side?__________________________

Given the code of a DNA molecule, what would be the code of the new DNA strand?

B: TACGGGGGCGTAACCACAACTWhat is the other side?__________________________


VC: How DNA copies itself

From DNA to protein


2.CODE IS READ. The code of the new strand (DNA copy) is READwith theT replaced with a new base Uracil or U.

A: ____________________________________

B: ____________________________________


3. CODE IS TRANSLATED. The code is read in groups of 3 called codons).

A: ____________________________________

B: ____________________________________


Find the Amino Acid sequence that is coded:

Use the following guide.

New copy (RNA) is read and translated

Genes(DNA)

Make copies of itself

Crossover (mixing of code)

Amino acids (protein) are formed

A trait is expressed

VC: What is phenotype


Cracking the Code

PROTEIN


While the copying of DNA is a very accurate process, what happens when a letter is altered?

VC: DNA Mutation
