How does DNA replicate

Formulating Models DNA must be copied, or replicated, before a cell can divide so that each of the two new cells that are formed by cell division has a complete set of genetic instructions. It is very important that the replicating process be accurate the new DNA molecules must be identical to the original. Watson and Crick noticed that their model for the three-dimensional structure of DNA provided a mechanism for accurate replication. 

each strand builds a complementary strand by base pairing with free nucleotides. This process is shown in Diagram a. When the free nucleotides have been hydrogen-bonded into place, their sugars and phosphates bond covalently to those on adjacent nucleotides to form the new backbone. Each strand of the original DNA molecule is now bonded to a new strand. 

Diagram b shows a small segment of a DNA molecule. Copy the base sequence onto a clean sheet of paper, being careful not to make copying errors. Show the steps of replication to produce two segments of the DNA. 

How does the base sequence of a newly synthesized strand compare with the original strand to which it is bonded  

If the original DNA segment is colored red and the free nucleotides are colored blue, what pattern of colors will the newly replicated DNA segments have Will all new segments have the same color pattern What does this pattern mean
