A. What is a nucleotide? What are the subunits of nucleotide?
B. What is a nitrogen base? Name the four nitrogen bases in DNA (A, C, G, T….remember the full names).
C. Explain the structure of DNA, why is it referred as Watson and Crick model? Given a sequence of DNA, you should be able to find its complementary nitrogen bases.For example the complementary nitrogen bases for AGTCGC sequence is
D. What is RNA? How many kinds of RNA, (mRNA, tRNA and rRNA), know the function of each one of them. Which one of these three RNA gets translated into protein?
C. What are the nitrogen bases in RNA (as opposed to DNA)? Remember T is replaced by U in RNA. Compare and contrast DNA and RNA (you will find a comparison table in your text book or the power point). You have to remember T in RNA is replaced by U.

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...
