Why is DNA replication considered a semi-conservative process?

• RNA will combine with DNA using the base pair rules during this process.

• DNA replication must occur before mitosis to produce identical daughter cells.

• DNA has two sides of complimentary base pairs held together by weak bonds.

• The new DNA molecules contain one strand of the original molecule and one new strand.

Prior to mitosis, a cell will undergo replication to copy the DNA before dividing. Which feature of DNA allows the replication to be semi-conservative and equip the new cell with an exact copy of the genes from the parent cell.

• DNA is single stranded

• DNA is transcribed into RNA before translation

• Hydrogen bonds hold the strands closely together

• Base pairing occurs between complimentary strands
