  1. QUAFF (kwaf) v. • to drink heartily • I offered her a sip, but she QUAFFED my entire soda. • Fraternity parties often involve the QUAFFING of large quantities of beverages. • Many of the senior citizens were guilty of QUAFFING far too much drink at the early bird special. PLEASE HAVE YOUR INB OPEN TO YOUR HOMEWORK FROM LAST NIGHT!!

  2. KEY CONCEPT DNA replication copies the genetic information of a cell.

  3. Replication copies the genetic information. • A single strand of DNA serves as a template for a new strand. • The rules of base pairing directreplication. • DNA is replicated during theS (synthesis) stage of thecell cycle. • Each body cell gets acomplete set ofidentical DNA.

  4. nucleotide The DNA molecule unzips in both directions. Proteins carry out the process of replication. • DNA serves only as a template. • Enzymes and other proteins do the actual work of replication. • Enzymes unzip the double helix. • Free-floating nucleotides form hydrogen bonds with the template strand.

  5. nucleotide new strand DNA polymerase • DNA polymerase enzymes bond the nucleotides together to form the double helix. • Polymerase enzymes form covalent bonds between nucleotides in the new strand.

  6. new strand original strand Two molecules of DNA • Two new molecules of DNA are formed, each with an original strand and a newly formed strand. • DNA replication is semiconservative.

  7. There are many origins of replication in eukaryotic chromosomes. Replication is fast and accurate. • DNA replication starts at many points in eukaryotic chromosomes. • DNA polymerases can find and correct errors.

  8. On the BACK of your notes: • Guanine, cytosine, thymine, and __________________ are the four __________________ in DNA. • In DNA, guanine always forms hydrogen bonds with __________________. • The process of __________________ produces a new copy of an organism’s genetic information, which is passed on to a new cell. • The double coiled, “staircase” shape of DNA is called a __________________. • What is the first step in the process of DNA replication? • Which enzyme is responsible for facilitating the hydrogen bonding between nucleotides in a new DNA molecule? • If the sequence of one single strand of DNA is C-A-A-G-T-A-G-G-C-, what is the sequence of the complementary strand?
