Homework for Monday:
Our next unit is DNA.
Answer the following questions. It doesn't matter to me how you get the information (resources posted on the blog under 'DNA,' using the modules, an online textbook, a Crash Course video etc).
But...YOU MUST GIVE A CITATION FOR EACH ANSWER. You can NOT use wikipedia.
1. What are the two chemical components of chromosomes?
2. Originally scientists thought that protein, not DNA was the genetic material. Why did they think this?
3. What was the significance of Frederick Griffith's study of Streptococcus pneumoniae ?
4. Describe the means by which Hershey and Chase established that DNA, not protein, was in fact the genetic material.
5. Draw and label a nucleotide.
6. Who built the first model of DNA and shared the 1962 Nobel Prize for the discovery of its structure?
7. Complete the table below, naming the five nitrogenous bases and put a check mark in the appropriate columns. Also indicate if the base is found in DNA (D), RNA (R) or both (B).
8. Draw and label four nucleotides, which make up two runs of a DNA ladder. Make sure that the orientation of sugars and phosphates it correct.
