(Learning Outcome A0 - A1)
Complete the reading first : "Proteins/Nucleic Acids" – Handout and use filled in
Notes #2 as well.
L.O. A – 0 Intro To The Importance Of DNA:
___ 1. List two specific examples of your cells making proteins.
___ 2. Name the three main nutrient groups/chemicals used by cells.
___ 3. What are the basic building blocks that make up a protein molecule?
___ 4. Many of the proteins/enzymes that a cell makes are crucial for the cell to properly
work, what does the cell have (use) in order to help it build these proteins properly?
___ 5 How many different amino acids are there, and give an example of how many
amino acids would have to be linked together in the proper sequence to make a
typical single large protein?
___ 6. If the sequence of amino acids is so little as one amino acid off (out of place), the
results can be devastating. Summarize Linus Pauling’s discovery (handout)
___ 7. If you look at one protein/enzyme common to all aerobic organisms, in general,
what does Table 1.2 illustrate. (see p. 47 of reading handout)
L.O. A – 1 Describe the Structure and Location of DNA
___ 1. What does "D.N.A." stand for?
___ 2. What three molecules make up a DNA nucleotide?
___ 3. DNA is double stranded and takes on a spiral shape called a ______________.
___ 4. What is the only difference between the four different DNA nucleotides?
___ 5. What is the name of the sugar found in a DNA nucleotide?
___ 6. Draw a basic shape of a purine base, and give the name of both purines.
___ 7. Draw a basic shape of a pyrimidine base, and give the name of both pyrimidines.
___ 8. A purine base will always complimentary base pair with what type of base?
___9. Thymine always joins to ____________.
___10. Cytosine always joins to ______________.
___11. What type of bonding holds complementary base pairs together?
___12. What is significant about a set of three bases in a row, called a codon?
___13. What makes up the vertical rails of a DNA ‘ladder”?
___14. What makes up the horizontal rungs of a DNA ‘ladder”?
___15. Normally, DNA is found in a long string wrapped around spherical proteins
called histones, what is the name of this thicker string?
___16. What must happen to DNA just prior to cell division, and what is the proper
name for this process?
___17. How many chromosomes do humans have?
___18. What is the definition of a gene?
