Station 4: Complete the complementary strand for the DNA sequence below.

A-T-A-A-T-C-G-A-G-A-G-A-T-T-C-A-A-T-C-G______________________________

If there are 20% of a random strand of DNA is composed of adenine bases, what percent of the DNA is guanine?

_______

T-A-T-T-A-G-C-T-C-T-C-T-A-A-G-T-T-A-G-C

80% Gunaine (G)

Station 5:In one sentence, answer the question below.

Why does the DNA of a cell replicate before the cell divides to make a two new cells?

____________________

DNA is copied before the cell divides to ensure that all new cells in the body have the same instructions for building the

body.

Station 6: Answer the question below in 1 sentence.

All living things have DNA, but not all living things have the same DNA.

Knowing this, what does the DNA of all living things have in common?

______________________

All DNA in every organism is composed of the same four nitrogenous bases (A T C G)

Station 7: Answer the question below in 2 sentences.

Why is the shape of DNA described as a double helix? (There are two reasons you should describe. Think about the two words!)

______________________

Double = 2, Helix = Twisted Ladder/Spiral Staircase shape

Station 8: Fill in the blanks below.

The two strands of DNA are said to be ________________ (opposites/complementary).

This is true because of the ____ _______ rule.

1

Base Pairs

Station 9:Which of the following make up the backbone of DNA?

Station 10:Correctly match the monomers to the polymers. Use the following words:

nucleotide, monosaccharide, amino acid, fatty acid

Protein _______________Carbohydrate _____________

Lipid: _______________DNA: ______________Amino Acid

MonosaccharideFatty AcidNucleotide

Station 11:Look at the diagram below and focus on the last picture on the right. In one sentence, what does

it mean that DNA replication is semi-conservative?

______________________________The DNA consist of ½ original (old) and ½ complementary (new)

strands.

Station 12: Read the information and answer the question.

When you mix oil and water in a cup, they do not mix. When you mix food coloring and water in a cup, they do mix. This means that oil does not dissolve in water.

What type of biomolecule is oil?__________________

Lipid

Station 13:Which of the following did Miss Rosalind Franklin help to discover?

- The function of DNA- How DNA was created- The structure of DNA

___________________

Station 14: Fill in the blanks in the paragraph. Use the

following words:antiparallel, double helix, complementary

DNA is in the shape of a double helix. The two sides, or strands, of DNA are complementary to one another. The direction of the DNA strands are said to be antiparallel because they run in opposite directions, allowing the bases to bond in the middle with the backbone on the outside.

Station 15:Draw the nucleotide below and then label the three parts.

1. Phosphate Group 2. Nitrogenous Base

3. Deoxyribose Sugar
