AP Bio Ch. 16 vocab

	A linking enzyme essential for DNA replication; catalyzes the covalent bonding of the 3' end of a new DNA fragment to the 5' end of a growing chain.
	An enzyme that catalyzes the elongation of new DNA at a replication fork by the addition of nucleotides to the existing chain.
	The form of native DNA, referring to its two adjacent polynucleotide strands wound into a spiral shape.
	An enzyme that untwists the double helix of DNA at the replication forks.
	A discontinuously synthesized DNA strand that elongates in a direction away from the replication fork.
	The new continuous complementary DNA strand synthesized along the template strand in the mandatory 5' ( 3' direction.
	The cellular process that uses special enzymes to fix incorrectly paired nucleotides.
	An enzyme that hydrolyzes DNA and RNA into their component nucleotides.
	The process of removing and then correctly replacing a damaged segment of DNA using the undamaged strand as a guide.
	Site where the replication of a DNA molecule begins.
	A virus that infects bacteria; also called a bacteriophage.
	An enzyme that joins RNA nucleotides to make the primer.
	A polynucleotide with a free 3´ end, bound by complementary base pairing to the template strand, that is elongated during DNA replication.
	A Y-shaped region on a replicating DNA molecule where new strands are growing.
	Type of DNA replication in which the replicated double helix consists of one old strand, derived from the old molecule, and one newly made strand.
	During DNA replication, molecules that line up along the unpaired DNA strands, holding them apart while the DNA strands serve as templates for the synthesis of complementary strands of DNA.
	An enzyme that catalyzes the lengthening of telomeres. The enzyme includes a molecule of RNA that serves as a template for new telomere segments.
