INFO:

Before a cell divides and DNA is passed from one cell to another, a complex process occurs. The DNA strands unwind and separate. Each strand makes a complementary strand by adding the appropriate nucleotides. As a result, there are now two double-stranded DNA molecules in the nucleus that contain the same information. This process is known as replication. This animation will describe the complex process in detail. This video can also be viewed at https://reach.cdc.gov/job-aids-resources
