The process of making new DNA molecules is semiconservative. This means that every new DNA molecule is composed of

• two completely identical strands of DNA.

• one original and one new strand of DNA.

• one strand of DNA and one strand of RNA.

• two strands that mix original and new DNA.

Please REPLICATE the following strand: ATC GCG ATT
