Describe the origin of each strand of the new double helices created after dna replication.

Each new strand which is also called the daughter strand is created by replicating a parent strand which is called the template strand.

Explanation:

DNA is the genetic material in most of the life forms. The DNA is replicated in a semiconservative way which means one strand in DNA is an old parent strand and another is a new strand.

Each strand in the DNA acts as the template strand during replication and DNA polymerase makes a new strand that is complementary to the parent strand. Therefore in a DNA double helix, one strand comes from parent DNA and another is newly made which is complementary to the parent strand.
