Question

Arrange the following events in DNA replication (top to bottom).

• A. DNA unwinds
• B. Strands separate
• C. Strands scanned
• D. New strands made
• E. Copies created

Answer 1

DNA is a double-helical structure which consists of two strands. During DNA replication, the gene machines or proteins unwind the double-helical structure. The separated strands get scanned and new strands are made (one for each old strand). This results in two copies of the DNA.
