viruses that infect bacteria
catalyzes the covalent bonding of the 3' end of a new DNA fragment to the 5' end of a growing chain.
this polymerase adds complimentary nucleotides one at a time to the strands
the form of DNA, two interwinding strands, running opposite each other
untwists the strands at the replication forks
DNA winds around the histones which is packaging in chromatin.
dna polymerase must move against it, building it up in segments call okazaki fragments
the strand that moves continuously along the dna polymerase
30-nm fiber forms loops that attach to a protein chromosome scaffold, making up a 300-nm fiber
DNA wound around histones
Short fragments of DNA that are a result of the synthesis of the lagging strand during DNA replication.
origins of replication
the spot where two strands of DNA begin forming the bubble and separating
adds the strands that make up the primer, can start from scratch.
an initial starting strand
Y shaped region where DNA starts to elongate and form complimentary strands
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.
single-strand binding protein
a clamp used to hold the and stabilize the single stranded dna until it can be used as a template
An enzyme that catalyzes the lengthening of telomeres. The enzyme includes a molecule of RNA that serves as a template for new telomere segments.
Repeated DNA sequences at the ends of eukaryotic chromosomes.
fixes strands of dna ahead of the replication fork, prepares it for splitting
change in phenotype and genotype due to assimilation of foreign dna
cuts out strands of broken strands of dna for repair
