Refers to semi-conservative replication of DNA. One strand of the old DNA is used as a template to replicate the other, new, strand of DNA. Thus you have four from two, but two of the four are old strands while the other two strands are new. Thus the name semi-conservative replication.
This is the type of DNA replication where the new strands of DNA are made from the old strands which are called templates. So, from two strands you get four. One new strand paired with the old template strand.
In the semi-conservative model, the resulting strand of DNA has one strand from the original DNA template and one strand that has been newly synthesized.
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.
Idea science is how my but is formef
A model is a physical three dimensional object that is created too appear as an object which is usually too small or large.
An abstract model is a mathematical model which contains an abstraction.
The most accurate, but not user friendly and usable model is the quantum mechanic atom model (QM model)
When a cell copies its DNA into the daughter cells with swag.
Telomerase
It means that the original strands are conserved.
it occurs in the nucleus

S Phase
semiconservative and dispersive
one strand of the DNA molecule
the reason for this experiment was to clarify how DNA replicates.There were 3 suggested models :the conservative.the semiconservative and the dispersive model. The experiment proved that DNA replicates in a semiconservative way i.e each of the parental strands serves as a template for the composition of a new strand.
density gradient centrifugation
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)
Semiconservative replication
