Question

I THINK ITS THE LAST ONE BUT IM NOT 100% SURE!

which of the following is true of a semiconservative model of replication

-each newly synthesized double helix of DNA contains one new strand and one old strand.
-DNA synthesized involves conserving only part of each od the original strands in a DNA molecule.
-the original DNA molecule is stored in the cell nucleus and severs as a template for creating copies containing two new strands.
-DNA synthesis involves conserving one strand of a double helix of DNA and discarding the other.

Answer 1

the answer is definitely not D. why would the cell dicard DNA? Everything is used and reused in a cell. The correct answer is A, after the helicase comes in and splits the DNA into two it just has to add the corresponding nucleotides and there you have it: two stands of DNA both containing a old stand and a new one
