DNA replication - Wikipedia
Within eukaryotes, DNA replication is controlled within the context of the cell cycle. As the cell grows and divides, it progresses through stages in the cell cycle; DNA replication takes place during the S phase (synthesis phase).
What is DNA replication? | Facts | yourgenome.org
DNA replication is the process by which DNA makes a copy of itself during cell division. The first step in DNA replication is to ‘unzip’ the double helix structure of the DNA molecule. This is carried out by an enzyme called helicase which breaks the hydrogen bonds holding the complementary bases of DNA together (A with T, C with G).
DNA Replication - The Cell - NCBI Bookshelf
As discussed in Chapter 3, DNA replication is a semiconservative process in which each parental strand serves as a template for the synthesis of a new complementary daughter strand. The central enzyme involved is DNA polymerase, which catalyzes the joining of deoxyribonucleoside 5′-triphosphates (dNTPs) to form the growing DNA chain.
DNA Replication | HowStuffWorks
Where DNA replication occurs depends upon whether the cells is a prokaryote or a eukaryote (see the RNA sidebar on the previous page for more about the types of cells). DNA replication occurs in the cytoplasm of prokaryotes and in the nucleus of eukaryotes.
Molecular mechanism of DNA replication (article) | Khan ...
DNA replication is semiconservative. Each strand in the double helix acts as a template for synthesis of a new, complementary strand. Each strand in the double helix acts as a template for synthesis of a new, complementary strand.
DNA Replication Steps and Process - ThoughtCo
DNA replication is the production of identical DNA helices from a single double-stranded DNA molecule. Each molecule consists of a strand from the original molecule and a newly formed strand. Each molecule consists of a strand from the original molecule and a newly formed strand.

DNA replication and RNA transcription and translation. Leading and lagging strands in DNA replication. Speed and precision of DNA replication. Molecular structure of DNA. Molecular mechanism of DNA replication. Mode of DNA replication: Meselson-Stahl experiment. DNA proofreading and repair.
DNA replication is extraordinarily accurate. DNA polymerase makes very few errors, and most of those that are made are quickly corrected by DNA polymerase and other enzymes that "proofread" the nucleotides added into the new DNA strand.
DNA Replication Flashcards | Quizlet
DNA REPLICATION: Before the lagging-strand DNA exits the replication factory, its RNA primers must be removed and the Okazaki fragments must be joined together to create a continuous DNA strand. The first step is the removal of the RNA primer.
