Study Guide- Exam 1  Chapter 8 DNA replication     ●   Only one strand is synthesized continuously and is called the leading strand. The        lagging strand is synthesized discontinuously in Okazaki fragments.     ●   RNA primase- initiator, adds short strands of RNA primer.    ●   DNA polymerase 3- can only elongate at 3’ end.     ●   DNA ligase- seals gap in lagging strand.    ●   DNA polymerase 1- replicates 5’ to 3’ direction, removes RNA primase and replaces it         with DNA nucleotides.           ○  10x -4 chance it makes a mistake,            ○  10 x-4 chance it doesn’t fix it. This is called a mismatch.           ○  DNA repair enzymes remove mismatch, or the next generation will have a               mutation.    ●   Nucleotide-
