<b>Eukaryotic</b> DNA <b>replication is</b> a conserved mechanism that restricts DNA 
<b>replication</b> to once per <b>cell</b> cycle. <b>Eukaryotic</b> DNA <b>replication</b> of <b>chromosomal</b> 
DNA <b>is</b>&nbsp;... The origin of <b>replication is</b> a particular sequence in a genome at which <b>replication</b> 
<b>is</b> initiated. ... A key prerequisite for DNA <b>replication is</b> that it must <b>occur</b> with 
extremely high fidelity and efficiency exactly once ... sequence elements and that 
controls <b>replication</b> of the entire <b>chromosome</b>, most <b>eukaryotic</b> replicators – with 
the&nbsp;... In <b>cell</b> biology, <b>eukaryotes</b> possess a regulatory system that ensures that DNA 
<b>replication</b> occurs only once per <b>cell</b> cycle. A key feature of the DNA <b>replication</b> 
mechanism in <b>eukaryotes is</b> that it <b>is</b> ... The following events must <b>occur</b> in order 
to activate the origin: the DNA helix has to open, the helicase must be activated, 
and&nbsp;... A telomere <b>is</b> a region of repetitive nucleotide sequences at each end of a 
chromosome, which ... During <b>chromosome replication</b>, the enzymes that 
duplicate DNA cannot continue their duplication all ... The telomeres <b>are</b> 
disposable buffers at the ends of chromosomes which <b>are</b> truncated during <b>cell</b> 
division; their presence&nbsp;... Free ends <b>would</b> otherwise create significant challenges to <b>cells</b> with respect to 
DNA <b>replication</b> and stability. <b>Cells</b> that <b>do</b> contain <b>chromosomes</b> with DNA ends,
&nbsp;... <b>Cell</b> division <b>is</b> the process by which a parent <b>cell</b> divides into two or more 
daughter <b>cells</b>. <b>Cell</b> division usually occurs as part of a larger <b>cell</b> cycle. In 
<b>eukaryotes</b>, there <b>are</b> two distinct types of <b>cell</b> division: a vegetative division ... In 
S phase, the <b>chromosomes are replicated</b> in order for the genetic content to be 
maintained. In molecular biology, DNA <b>replication is</b> the biological process of producing two 
identical ... Once <b>replication is</b> complete, it <b>does</b> not <b>occur</b> again in the same <b>cell</b> 
cycle. This <b>is</b> ... <b>Eukaryotes</b> initiate DNA <b>replication</b> at multiple points in the 
<b>chromosome</b>, so <b>replication</b> forks meet and terminate at many points in the 
<b>chromosome</b>. <b>Replication</b> timing refers to the order in which segments of DNA along the length 
of a <b>chromosome are</b> duplicated. ... In <b>eukaryotic cells</b> (cells that package their 
DNA within a nucleus), <b>chromosomes</b> consist of very ... Figure 2 shows a cartoon 
of how this <b>is</b> generally envisioned to <b>occur</b>, while Figure 3 shows an animation

occurrence in <b>eukaryotic cells</b> in which the genome <b>is replicated</b> more than once 
per cell ... structure plays a large role in determining where <b>replication will occur</b>. 
The <b>replication</b> origins <b>are</b> not distributed evenly throughout the <b>chromosome</b>. Extrachromosomal DNA (abbreviated ecDNA) <b>is</b> any DNA that <b>is</b> found off the 
<b>chromosomes</b>, either inside or outside the nucleus of a cell. Most DNA in an 
individual genome <b>is</b> found in <b>chromosomes</b> contained in the nucleus. Multiple 
forms of extrachromosomal DNA <b>exist</b> and serve important biological ...
