DNA polymerase catalyzes the process of DNA replication and repair during cellular respiration. Learn about DNA polymerase function, structure, and types.

Learn about Taq polymerase. Find out Taq polymerase function as well as why and where Taq polymerase is used in polymerase chain reactions for cloning DNA.

Explore the function and structure of DNA polymerase in this short, informative video lesson. Learn how it replicates DNA, then take a quiz to review.

Gain an understanding of DNA polymerase and RNA polymerase. Learn what DNA polymerase does and explore the functions of RNA primase and their end products.

The order of DNA replication enzymes is very important to the process of replication. The four main enzymes that are involved are DNA helicase, RNA primase, DNA polymerase, and DNA …

RNA polymerase is the main enzyme involved in the transcription process. Like DNA polymerase, RNA polymerase also adds new nucleotides to the 3' end of the strand thus, growing the RNA …

Learn about the role of the RNA primer in DNA replication, the RNA primer's function and sequence, complementary nucleotides, and synthetic primers.

Learn what DNA ligase does within the cell. Understand details about how restriction enzymes work. See examples of DNA ligase functions and structures.

The main function of the Okazaki fragments to enable DNA polymerase to synthesize the lagging strand despite it being oriented in the opposite direction.

The trigger for DNA replication is the activation of a protein called helicase. Helicase unwinds the DNA strands and breaks the hydrogen bonds between the nucleotides in either strand of DNA.
