How is DNA copied? How does the mechanism for copying DNA explain the fact that every new DNA molecule includes one old strand and one newly made strand?
What will be an ideal response?
During replication, DNA's two strands are separated as if the spiral ladder were unzipped down the middle. Each strand then serves as a template for building a new partner. This is possible because of the specific way the nucleotides pair?because A always pairs with T, and G always pairs with C. Free nucleotides bind to nucleotides on the template DNA strand and are then attached to the new, growing DNA strand by enzymes called DNA polymerases. Because each old strand serves as a template for building a new strand, every new DNA molecule includes one old strand and one new strand.
