The analysis of the nitrogenous bases of the nucleic acid of a newly discovered virus showed 20% adenine, 40% guanine, 10% thymine, and 30% cytosine. The viral nucleic acid is most likely single stranded RNA double stranded DNA double stranded RNA single stranded DNA
Adenine, cytosine, guanine are present in both DNA and RNA. Thymine and uracil are exclusive for DNA and RNA respectively. Explain why it is advantageous for DNA to contain thymine, not uracil. 0. Gout is a common, painful form of arthritis. It causes swollen, red, hot and stiff joints. Gout happens when uric acid builds up in your body. It is treated with allopurinol. What is the biochemical bas is of this treatment?

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...
