Today i hope to describe about Copying DNA. this is first post for Copying DNA..
• Polymerase Chain Reaction
• Also called PCR
• A method of making many copies of a piece of DNA
Steps in Copying DNA
• A DNA molecule is placed in a small test tube
• DNA polymerase that can work at high temps is added
• The DNA is heated to separate the two strands
• Primers, short pieces of DNA complementary to the ends of the molecule to be copied, are added
Copying DNA
• The tube is cooled, and DNA polymerase adds new bases to the separated strands
