1.What tautomeric form of the bases do Watson and Crick predict in their structure?
2.How many nucleotide pairs (residues) occur in DNA before the helix repeats itself?
3. According to their model, How far apart(vertical distance) are the residues on each chain?
Homework Answers
1. Watson and Crick predict keto form of the bases in their structure, forming an adenine-thymine pair and a guanine-cytosine pair.
2. 10 nucleotide pairs occur in DNA before the helix repeats itself.
3. According to their model, the residues are 0.34 nm or 3.4 A apart (vertical distance) on each chain.

What are the three functional groups that comprise a nucleotide? What do nucleotides have in common with amino acids or simple sugars? When the structure of DNA was first elucidated, many biologists quickly saw how this structure explained the passage of information from one generation to another. How does the structure of DNA explain generation-to-generation flow of information? In other words, give a brief description of the structure of DNA and tell how this structure allows for replication. Which of...

1 Overview and Background Many of the assignments in this course will introduce you to topics in computational biology. You do not need to know anything about biology to do these assignments other than what is contained in the description itself. The objective of each assignment is for you to acquire certain particular skills or knowledge, and the choice of topic is independent of that objective. Sometimes the topics will be related to computational problems in biology, chemistry, or physics,...
