All of the following are true about DNA replication except ___.

• It is semiconservative
• It occurs during the S-phase of the cell cycle 
• It allows daughter cells to have exact copies of the genetic code
• It reduces the chromosome number by half for the production of gametes

Replication of DNA 

• Produces mRNA and tRNA molecules
• Produces only new DNA 
• Produces two molecules, each of which is half new and half old DNA joined lengthwise to each other
• Generates excessive DNA, which eventually causes the nucleus to divide

DNA polymerase 

• Is an enzyme 
• Adds new nucleotides to the template strand 
• Proofreads DNA strands to see that they are correct 
• All of these are functions of DNA polymerase
