WEBcorrects "overwinding" ahead of replication forks by breaking, swiveling, and rejoining DNA strands. An enzyme that creates a short RNA primer for initiation of DNA replication. The strand in replication that is copied 3' to 5' as Okazaki fragments and then joined up. Start studying DNA Replication Labeling.

WEBSpecialized proteins recognize the origin, bind to this site, and open up the DNA. As the DNA opens, two Y-shaped structures called replication forks are formed, together making up what's called a replication bubble. The replication forks will move in opposite directions as replication proceeds.

WEBDNA Replication. Click the card to flip 👆. process by which DNA is copied in a cell (before the cell divides by mitosis (healing self), meiosis (Sperm and egg), or binary fission (Bacteria to reproduce)) Semi-conservative Replication. DNA molecule must untwist as it replicates. DNA must copy its two strands roughly simultaneously.

WEBThe replication fork is a region where a cell's DNA double helix has been unwound and separated to create an area where DNA polymerases and the other enzymes involved can use each strand as a template to synthesize a new double helix. An enzyme called a helicase catalyzes strand separation.

WEBThe replication of DNA occurs during the synthesis phase, or S phase, of the cell cycle, before the cell enters mitosis or meiosis. The elucidation of the structure of the double helix provided a hint as to how DNA is copied. Recall that adenine nucleotides pair with thymine nucleotides, and cytosine with guanine.

WEBThe replication fork is the branched (forked) DNA at either end of the replication bubble. The replication complex is the group of proteins that help synthesize the new DNA strands. A replication unit is any chunk of DNA that is capable of being replicated — e.g. a plasmid with an origin of replication (ORI) is a replication unit.

The Replication Fork: Understanding the Eukaryotic Replication
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3627427/
WEBJan 29, 2013 · DNA replication, at its most fundamental, is the action of DNA polymerases synthesizing a DNA strand complementary to the original template strand. To synthesize DNA, the double-stranded DNA is unwound by DNA helicases ahead of polymerases, forming a replication fork containing two single-stranded templates.
