(1) The conversion of a normal animal cell to a cancerous cell. (2) A change in genotype and phenotype due to the assimilation of external DNA by a cell.
A virus that infects bacteria; also called a phage.
The form of native DNA, referring to its two adjacent polynucleotide strands wound into a spiral shape.
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.
A Y-shaped region on a replicating DNA molecule where new strands are growing.
An enzyme that catalyzes the elongation of new DNA at a replication fork by the addition of nucleotides to the existing chain.
Origin of Replication
Site where the replication of a DNA molecule begins.
The new continuous complementary DNA strand synthesized along the template strand in the mandatory 5' -> 3' direction.
A discontinuously synthesized DNA strand that elongates in a direction away from the replication fork.
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.
A polynucleotide with a free 3' end, bound by complementary base pairing to the template strand, that is elongated during DNA replication.
An enzyme that joins RNA nucleotides to make the primer.
An enzyme that untwists the double helix of DNA at the replication forks.
A protein that functions in DNA replication, helping to relieve strain in the double helix ahead of the replication fork.
An enzyme that hydrolyzes DNA and RNA into their component nucleotides.
The protective structure at each end of a eukaryotic chromosome. Specifically, the tandemly repetitive DNA at the end of the chromosome's DNA molecule.
An enzyme that catalyzes the lengthening of telomeres. The enzyme includes a molecule of RNA that serves as a template for new telomere segments.
(genetics) the process whereby DNA makes a copy of itself before cell division
DNA model where both strands of DNA remain in tact and the 2 daughter strands form 1 helix together
each strand of BOTH daughter molecules contains a mixture of old and newly synthesized DNA
Separate strands that run in a different direction. In a DNA molecule, one strand is in the 3' to 5' orientation, and the other is in the 5' to 3'orientation.
