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 out High …

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.

Identify components of DNA, explain how the nucleotide sequence specifies some traits of an organism, and examine scientific explanations for the origin of DNA.

Key points: There were three models for how organisms might replicate their DNA: semi-conservative, conservative, and dispersive. The semi-conservative model, in which each strand of DNA serves as …

The structure of DNA unlocked the door to understanding many aspects of DNA's function, such as how it was copied and how the information it carried was used by the cell to make proteins.

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 can have a big …

Composed of a sugar-phosphate backbone and base pairs (adenine-thymine, guanine-cytosine), DNA stores genetic information, replicates, and expresses traits. The human genome contains 6 billion …

DNA replication is a precise process where DNA unwinds and splits into two strands. Each strand then serves as a template for a new DNA molecule. The leading strand is built continuously, while the …
