Understand the process of DNA replication: DNA replication is the process by which a cell duplicates its DNA, ensuring that each daughter cell receives an exact copy of the genetic material.
Identify the role of DNA polymerase: DNA polymerase is an enzyme that plays a crucial role in DNA replication. Its primary function is to synthesize new DNA strands by adding nucleotides to a pre-existing strand.
Recognize the direction of synthesis: DNA polymerase adds nucleotides in the 5' to 3' direction, meaning it reads the template strand in the 3' to 5' direction.
Differentiate between leading and lagging strands: During replication, the leading strand is synthesized continuously, while the lagging strand is synthesized in short segments called Okazaki fragments.
Clarify the role of other enzymes: Other enzymes, such as helicase, are responsible for unwinding the DNA double helix, and ligase joins Okazaki fragments on the lagging strand.
