Question

When one DNA molecule is copied to make two new DNA molecules, the resulting DNA molecules contain A) none of the parent DNA. B) 50% of the parent DNA. C) 75% of the parent DNA. D) 100% of the parent DNA

Answer 1

50% of the parents DNA

Step-by-step explanation:

This is because the new DNA molecule contains a parent strand and a new daughter strand. The parent strand serves as a template for the synthesis of a new strand reason why DNA replication is said to be a semi-conservative process.
