DNA And Protein Synthesis Lab Report

Module 2 Section 2
EXPERIMENT: DNA & Protein Synthesis
Exercise 1 – Modeling DNA
1. List the four bases which are found in DNA. (1 pt) The four bases found in DNA are cytosine, adenine, guanine and thymine.

2. Fit any six nucleotides together to form a row, then list the six nucleotides in the order you used them. Work with your model pieces and try fitting the bases together to make a double strand as shown in Figure 9 of the lab manual. Which nucleotides form pairs? (2 pts) The nucleotides form pairs as follows: guanine-cytosine and adenine-thymine.

3. The following list indicates the bases on one strand of a DNA molecule. Write in the names of the bases that could pair with each to make the complementary strand. (2 pts)

cytosine
What are the three molecular components of a DNA nucleotide? (3 pts)
The three molecular components of a DNA nucleotide are a sugar (deoxyribose), a phosphate group, and a nitrogneous base.

Exercise 2 - The Globin Gene
1. Use the DNA coding strand to complete the DNA molecule by creating a complimentary strand. To do this, remember that the nucleotide base pair association between DNA is A -T and G –C. Write the complimentary strand. (2
