DNA ReplicationDNA Transcription: replication of DNA, process of copying DNA

DNA is ALWAYS copied during_____________________________________

Before ____________ and ______________ This takes place during the _________________ phase of ______________________________

Steps in DNA replication1. The DNA molecule is _________________ down the middle (_________________________________) by

______________________ breaking the ___________________________________________

a. Forms a ______________________________

b. Similar to a zipper

2. The _______________________________________ on each side of the molecule are used as a

___________________________________________________________.

3. ___________________________________ are added to each individual strand by

_________________________________ (enzyme).

4. Each new cell can get a _____________________________________ of all the DNA

a. Semi-conservative: _________________________________________________________________

1DNA Replication:

Enzymes and Proteins Involved: Function:1. DNA Helicase

2. DNA Primase

3. DNA Polymerase

4. DNA Ligase

Leading strand is copied ____________________ from a replication origin in the _____ direction that the _____________________________________ movesLagging strand is copied _____________________ from a replication origin in the ____________ direction that the _________________________ moves

The small pieces created are called ______________________________You are left with ______ EXACTLY ____________________ molecules of double helix DNA
