DNA replication is said to be 'semi-conservative' because the two new daughter DNA molecules are "Half old" and "Half new". Half the original DNA molecule is saved, or conserved in the daughter molecules.
DNA replication is called semi-conservative because the template strand is conserved in the new DNA double strand. When it is copied, one strand is old and one is new. This occurs each time DNA is replicated.
When a cell copies its DNA into the daughter cells with swag.
it occurs in the nucleus
21 days
S Phase
semiconservative and dispersive
one strand of the DNA molecule
DNA replication is : semiconservative, bidirectional, begins at unique sites (origins)
Semiconservative replication
Conservative replication and semiconservative replication are the ways DNA reproduces itself. The difference being whether the newly formed strands pair with each other or with an old one.
Telomerase
It means that the original strands are conserved.
Watson and Crick mentioned it slightly in their paper but didn't propose a full method of replication. a number of different people collaborated to work out the full model of replication which is still no totaly finished, (few proteins left to find)
