Which of the following is true of a semi-conservative model of replication?
1) each newly synthesized double helix of dna contains one new strand and one old strand.
2)dna synthesis involves conserving only part of each of the original strands in a dna molecule.
3)the original dna molecule is stored in the cell nucleus and serves as a template for creating copies containing two new strands.
4)dna synthesis involves conserving one strand of a double helix of dna and discarding the other.

Abody cell has been growing and at synthesis proteins.in the nucleus of this body cell,dna replication is taking place. and a copy of the cells genetic material is copied.which of the following is the best conclusion you can make about the life cycle of this cell ? a) the cell is ready to undergo mitosis.and a chemical signal will send the cell to prophase b)the cell is undergoing meiosis and will cross over the genetic material next c)the cell is in the s phase of interphase and will move next to the g2 phase d) the cell is in the g2 phase of the interphase and is ready to begin diving
