2. DNA replication - Wikipedia

   en.wikipedia.org/wiki/DNA_replication

   DNA Pol I has a 5′ to 3′ exonuclease activity in addition to its polymerase activity, and uses its exonuclease activity to degrade the RNA primers ahead of it as it extends the DNA strand behind it, in a process called nick translation. Pol I is much less processive than Pol III because its primary function in DNA replication is to create ...

3. Eukaryotic DNA replication - Wikipedia

   en.wikipedia.org/wiki/Eukaryotic_DNA_replication

   DNA replication on the lagging strand is discontinuous. In lagging strand synthesis, the movement of DNA polymerase in the opposite direction of the replication fork requires the use of multiple RNA primers. DNA polymerase will synthesize short fragments of DNA called Okazaki fragments which are added to the 3' end of the primer. These ...

   en.wikipedia.org/wiki/Molecular_Structure_of...

   The two base-pair complementary chains of the DNA molecule allow replication of the genetic instructions. The "specific pairing" is a key feature of the Watson and Crick model of DNA, the pairing of nucleotide subunits. [5] In DNA, the amount of guanine is equal to cytosine and the amount of adenine is equal to thymine. The A:T and C:G pairs ...

5. DNA polymerase - Wikipedia

   en.wikipedia.org/wiki/DNA_polymerase

   A DNA polymerase is a member of a family of enzymes that catalyze the synthesis of DNA molecules from nucleoside triphosphates, the molecular precursors of DNA. These enzymes are essential for DNA replication and usually work in groups to create two identical DNA duplexes from a single original DNA duplex. During this process, DNA polymerase ...

6. Helicase - Wikipedia

   en.wikipedia.org/wiki/Helicase

   Helicases are also classified as α or β depending on if they work with single or double-strand DNA; α helicases work with single-strand DNA and β helicases work with double-strand DNA. They are also classified by translocation polarity. If translocation occurs 3’-5’ the helicase is type A; if translocation occurs 5’-3’ it is type B ...

7. DNA synthesis - Wikipedia

   en.wikipedia.org/wiki/DNA_synthesis

   DNA replication also works by using a DNA template, the DNA double helix unwinds during replication, exposing unpaired bases for new nucleotides to hydrogen bond to. Gene synthesis, however, does not require a DNA template and genes are assembled de novo. DNA synthesis occurs in all eukaryotes and prokaryotes, as well as some viruses. The ...

8. Challenges of DNA technology to identify missing children

   "Children of color, families of color, have a smaller footprint in the DNA databases," Bischoff said. Bischoff said there is one tool that can be invaluable in helping identify these children.

9. Introduction to genetics - Wikipedia

   en.wikipedia.org/wiki/Introduction_to_genetics

   DNA can be copied very easily and accurately because each piece of DNA can direct the assembly of a new copy of its information. This is because DNA is made of two strands that pair together like the two sides of a zipper. The nucleotides are in the center, like the teeth in the zipper, and pair up to hold the two strands together.
