DNA Helicase moves along the DNA and breaks the hydrogen bonds between the two strands. Single-strand binding proteins (SSBs) keep the strands from joining back together. (replication bubble created) Replication bubbles form at multiple sites along the DNA molecule, greatly speeding up replication.

1. Draw the DNA double helix, with the sequence on the 5’ to 3’ strand: ACCGTATTGATC. Label the 5’ and 3’ on each strand. 2. Helicase (() begins to unwind the DNA. 3. DNA polymerase. adds complementary bases in the 5’ to 3’ direction (leading strand). 4. DNA polymerase adds complementary bases discontinuously in the 5’ to 3’ direction

Steps of DNA replication. 1. DNA helicase (enzyme) unwinds the DNA. The junction between the unwound part and the open part is called a replication fork. 2. DNA polymerase. adds the complementary nucleotides and binds the sugars and phosphates. DNA polymerase travels from the 3' to the 5' end. The DNA is called the . template. strand. 3. DNA polymerase adds

DNA gyrase wraps DNA around it, cuts both strands of DNA. then passes DNA through the gap of broken strands and reforms the phosphodiester backbone. replication fork. Origin of replication. DNA replication begins at specific regions of DNA referred to as 'Origins of …

DNA must be duplicated if cells are to undergo division. replication is “semi-conservative” occurs in nucleus. each strand is used as a template for a new, complementary strand. Several Key Steps: DNA strand is unwound by enzyme called helicase, using ATP as energy source

B. Steps in DNA replication. 1. Parental DNA strands separate/unzip (H bonds between the nitrogen bases break) a. This unzipping begins in DNA replication at the ‘origin of replication’, a specific place in the DNA. b. This creates a single-stranded (nitrogen bases are unbound) area in the DNA called the REPLICATION FORK. 2.
