Cards in this set: Term Semiconservative model Definition When DNA replicates the new DNA is half parent and half daughter DNA. Term Goal of DNA replication Definition To produce DNA for daughter cells Term When does DNA replicate? Definition S-phase Term 5' has _______ on the end of it? Definition Phosphate Term 3' has ________ on the end of it? Definition A hydroxyl Term In which direction does DNA replicate? Definition 5' to 3' Term Strands of DNA are? Definition Anti-parallel Term What enzyme pulls apart DNA? Definition Helicase Term Where are bubbles likely to form in DNA? Definition Where there are many A-T pairs. (A-T pairs have only two hydrogen bonds and are easier to pull apart than G-C pairs which have three hydrogen bonds.) Term DNA polymerase Definition Joins nucleotides to open DNA strand Term What does DNA first do in DNA replication? Definition Flattens and unzips Term What enzyme adds bases to new DNA? Definition DNA polymerase Term What enzyme connects the Okazaki Fragments? Definition DNA ligase Term Okazaki Fragments Definition The pieces of new DNA on the lagging strand Term Strand the Okazaki Fragments are on Definition Lagging Strand Term Strand with continuous synthesis Definition Leading Strand Term Strand with discontinuous synthesis Definition Lagging Strand Term Benefits of DNA replication Definition Ensures all somatic cells have same DNA; Copies DNA for gametes Term Why is DNA so accurate? Definition DNA polymerase and DNA ligase proofread DNA and repair injured DNA Term Draw DNA replication. Definition {image:64823|center}
