Question: The regular pairing that occurs between the two strands of a DNA double helix is the key to how DNA is replicated (copied). During replication, a double helix is unwound, and new nucleotides are paired up appropriately with each existing strand. This ultimately produces two new double helices, each identical to the original. This process of DNA replication is said to be semi-conservative. What does this mean? Need Assignment Help? Option A after replication, each new DNA strand contains one of the original strands Option B DNA can be converted to RNA Option C RNA can be converted to DNA Option D the process of replication reuses old nucleotides Option E DNA double helices are split apart during the process of replication
