294461466 | transformation | (1) the conversion of a normal animal cell to a cancerous cell | |
294461467 | bacteriophage | a virus that infects bacteria (phage) | |
294461468 | phage | a virus that infects bacteria (bacteriophage) | |
294461469 | double helix | the form of native DNA, referring to its two adjacent polynucleotide strands wound into a spiral shape | |
294461470 | semiconservative model | 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 | |
294461471 | origins of replication | sites where the replication of a DNA molecule begins | |
294461472 | replication fork | a Y-shaped region on a replication DNA molecule where new strands are growing | |
294461473 | DNA polymerase | an enzyme that catalyzes the elongation of new DNA at a replication fork by the addition of nucleotides to the existing chain | |
294461474 | leading strand | the new continuous complimentary DNA strand synthesized along the template strand in the mandatory 5'-->3' dirrection | |
294461475 | lagging strand | a discontinuously synthesized DNA strand that elongates in a direction away from the replication fork | |
294461476 | DNA ligase | 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 | |
294461477 | primer | an already existing RNA chain bound to template DNA to which DNA nucleotides are added during DNA synthesis | |
294461478 | primase | an enzyme that joins RNA nucleotides to make the primer | |
294461479 | helicase | an enzyme that untwists the double helix of DNA at the replication fork | |
294461480 | single-strand binding protein | 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 complimentary strands of DNA | |
294461481 | mismatch repair | the cellular process that uses special enzymes to fix incorrectly paired nucleotides | |
294461482 | nuclease | a team of enzymes that hydrolyze DNA and RNA into their component nucleotides | |
294461483 | nucleotide excision repair | the process of removing and then correctly replacing a damaged segment of DNA using the undamaged strand as a guide | |
294461484 | telomere | The protective structure at each end of a eukaryotic chromosome. Specifically, the tandemly repetitive DNA at the end of the chromosome's DNA molecule. | |
294461485 | telomerase | An enzyme that catalyzes the lengthening of telomeres. The enzyme includes a molecule of RNA that serves as a template for new telomere segments. |
