There were three basic models for DNA replication that had been proposed by the scientific community after the discovery of DNA's structure. These models are illustrated in the diagram …

Key points: DNA replication is semiconservative. Each strand in the double helix acts as a template for synthesis of a new, complementary strand. New DNA is made by enzymes called …

Here, we focus on the Meselson-Stahl experiment, which proved DNA replication is semi-conservative. In this process, each new DNA pair consists of one old strand and one new …

DNA replication occurs through the help of several enzymes. These enzymes "unzip" DNA molecules by breaking the hydrogen bonds that hold the two strands together.

Unit 12: DNA as the genetic material About this unit This unit is part of the Biology archive. Browse videos and articles by topic. For our most up-to-date, mastery-enabled courses, check …

DNA helps make us who we are, but how exactly does it work? In this unit, we'll examine the nitty gritty of replication, transcription, and translation, and learn how seemingly small mutations …

During DNA replication, the two strands of the DNA double helix are unwound and separated by enzymes. Each strand then serves as a template, or guide, for synthesizing a new, …
