I think the best way to make a comparison is to make a chart.
00:03
So let's make us a chart with prokaryotes here, and we're going to compare that to ucariotes in terms of like chromosome structure and dna replication.
00:22
And so here, let's start by talking about the continuity of dna replication.
00:29
In prokaryotes, dna is usually continuously replicated.
00:35
However, in eukaryotes, replication only occurs during s -phase.
00:49
And remember, s -phase is the middle phase in interface, and it's the synthesis phase.
00:55
And so in eukaryotic cells, replication of dna tends to be restricted to s -phase.
01:02
If we look at oris, so the prokaryotes typically contain only one origin of replication.
01:10
If we compare that to eukaryotes, they contain many.
01:17
And of course, we can't put a number here because it's going to be dependent on what species of eukaryote we're talking about.
01:23
And so the fact is eukaryotic chromosomes usually carry many ores so that replication is efficient and corresponds with cell division generation times...
