Friday, November 8, 2013
A DNA NUCLEOTIDE CONSISTS OF:
A. Ribose sugar, Nitrogen base, Phosphate
B. Deoxyribose sugar, Gene, Phosphate
C. Deoxyribose sugar, Nitrogen base, Nucleic Acid
D. Deoxyribose sugar, Nitrogen base, Phosphate
A GENE IS MADE UP OF A SEQUENCE OF ________ AND
IS FOUND ON A _________
A. Chromosomes…Nucleotide
B. Adenines…Chromosome
C. Nucleotides…Chromosome
D. Traits…Nucleotide
WHICH SERIES IS ARRANGED IN CORRECT
ORDER ACCORDING TO DECREASING SIZE OF
STRUCTURES?
A. Nitrogenous Base, Nucleus, Chromosome, Nucleotide, Gene
B. Nucleotide, Chromosome, Nitrogenous Base, Nucleus, Gene
C. Nucleus, Chromosome, Gene, Nucleotide, Nitrogenous Base
D. Chromosome, Nucleus, Nitrogenous Base, Nucleotide, DNA
THE DNA POLYMER…
• Think back to BIOMOLECULES.
• All living things are made of BIOMOLECULES!
(carbohydrates, lipids, proteins and nucleic acids)
• All living things must be made of GENETIC MATERIAL in
order to reproduce.
• SO ALL LIVNG THINGS HAVE DNA!
The components that make up the genetic code
are common to all organisms!
Same NUCLEOTIDES, same BACKBONE same
BASE-PAIRS, same HYDROGEN BONDS!
The instructions for
making proteins (and
traits) are in the
sequence of nucleotides!
These are the GENES
that hold our similarities
or differences!

Information for everything about an organism is carried in
the order of bases in their DNA, like a language.
The more alike two organisms are, the more alike their order
of bases will be (because they will have similar traits!)

YOUR TURN TO PRACTICE!
1. Fill out the COMPLIMENTARY DNA strands on each strip!
2. Cut all the pictures and gene segments apart from one another.
3. The human DNA strand is: ATG-TAC-AAC-GGA-CAG. Glue this one at the
top of your notebook page!
4. Put the images in order from most to least related to human in your
notebooks.
5. Place the gene segments with the organism that you predict it to belong to,
based on what you have learned today.
6. Once you have had me check, glue them next to each other!
