DNA Replication Terms 2' deoxyribonucleoside triphosphate - The building blocks of DNA replication. A five- membered, oxygen-containing ribose sugar ring that has three phosphate groups attached to its 5' carbon and either an adenine, cytosine, guanine, or thymine base group attached to its 1' carbon. Base-pair excision - One class of DNA repair system. Recognizes and removes single nucleotide mutations that result from unnatural bases. Daughter strand - Refers to the newly synthesized strand of DNA that is copied via the addition of complementary nucleotides from one strand of pre-existing DNA during DNA replication. DNA Helicase - The enzyme responsible for separating the two strands of DNA in a helix so that they can be copied during DNA replication. DNA Ligase - The enzyme responsible for sealing together breaks or nicks in a DNA strand. Responsible for patching together Okazaki fragments on the lagging strand during DNA

Unformatted text preview: replication. DNA Polymerase - The enzyme responsible for catalyzing the addition of nucleotide substrates to DNA both during and after DNA replication. Primase - The enzyme responsible for initiating synthesis of RNA primers on the lagging strand during DNA replication. Holoenzyme - A term used to describe a collection of different enzymes that work together in a given process such as DNA replication. Hydrolysis - The process in which water is chemically added to a molecule. Lagging strand - In DNA replication, the strand of pre-existing DNA that is oriented in the 5' to 3' direction with respect to the direction of replication on which synthesis is discontinuous. Leading strand - In DNA replication, the strand of pre-existing DNA that is oriented in the 3' to 5' direction with respect to the direction of replication on which replication is continuous....
