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...
