Bruce William Stillman

He developed a biochemical system to study DNA replication-coupled chromatin assembly in a test tube and discovered proteins such as Chromatin Assembly Factor-1 (CAF-1) that cooperate with the DNA replication machinery to assemble new histones onto the DNA.

Caulimoviridae

As replication requires the use of RNA intermediate, viruses from the Caulimoviridae family are not true dsDNA viruses - instead they are termed DNA reverse-transcribing viruses.

Chemoton

The basic assumption of the model is that life should fundamentally and essentially have three properties: metabolism, self-replication, and a bilipid membrane.

Chromosomal rearrangement

This instability is usually due to the propensity of these regions to misalign during DNA repair, exacerbated by defects of the appearance of replication proteins (like FEN1 or Pol δ) that ubiquitously affect the integrity of the genome.

Cilevirus

The 286 kDa protein is a polyprotein involved in virus replication and has four conserved domains: methyltransferase, protease, helicase and an RNA dependent RNA polymerase.

Clanking replicator

In his short story "Crabs on the Island" (1958) Anatoli Dneprov speculated on the idea that since the replication process is never 100% accurate, leading to slight differences in the descendants, over several generations of replication the machines would be subjected to evolution similar to that of living organisms.

DinI-like protein family

The SOS response, a set of cellular phenomena exhibited by eubacteria, is initiated by various causes that include DNA damage-induced replication arrest, and is positively regulated by the co-protease activity of RecA.

DNA demethylation

The passive process takes place in the absence of methylation of newly synthesised DNA strands by DNMT1 during several replication rounds (for example, upon 5-Azacytidine treatment).

DNAA

DnaA is a replication initiation factor which promotes the unwinding or denaturation of DNA at oriC, during DNA replication in prokaryotes.

E2F

E2F target genes encode proteins involved in DNA replication (for example DNA polymerase, thymidine kinase, dihydrofolate reductase and cdc6), and chromosomal replication (replication origin-binding protein HsOrc1 and MCM5).

Electronic organ

The first full electronic church organ was built in 1939 by Jerome Markowitz, founder of the Allen Organ Company, who had worked for years to perfect the replication of pipe organ sound through the use of radio tube based oscillator circuitry.

Errett

Errett Callahan (born 1937), American archaeologist, flintknapper, and pioneer in experimental archaeology and lithic replication studies

Force spectroscopy

In this way a great deal has been learned in recent years about the mechanochemical coupling in the enzymes responsible for muscle contraction, transport in the cell, energy generation (F1-ATPase), DNA replication and transcription (polymerases), DNA unknotting and unwinding (topoisomerases and helicases), and so on.

Hanna Tuulikki

She studied Environmental Art at the Glasgow School of Art and had a residency in Cromarty, where she recorded people imitating the sea on the CD 100 Breaths, 100 Waves, and a replication of a dawn chorus on Salutations To The Sun.

Hepatitis C virus cis-acting replication element

The Hepatitis C virus (HCV) cis-acting replication element (CRE) is an RNA element which is found in the coding region of the RNA-dependent RNA polymerase NS5B.

Heterobasidiomycetes

In addition to having septate basidia, heterobasidiomycetes also frequently possess large irregularly shaped sterigmata and spores that are capable of self-replication - a process where a spore, instead of germinating into a vegetative hypha, gives rise to a sterigma and a new spore, which is then discharged as if from a normal basidium.

History of artificial life

Homer Jacobson illustrated basic self-replication in the 1950s with a model train set – a seed "organism" consisting of a "head" and "tail" boxcar could use the simple rules of the system to consistently create new "organisms" identical to itself, so long as there was a random pool of new boxcars to draw from.

Human foamy virus

Reverse transcription of the genome occurs at a later step in the replication cycle, which results in the infectious particles having DNA rather than RNA, this also leads to less integration in the host genome.

Infonic

iOra Geo-Replicator is a geo-replication technology which improves Microsoft SharePoint access for users at the edge of large military, commercial and aid organizations.

International Committee on Taxonomy of Viruses

The database classifies viruses based primarily on their chemical characteristics, genomic type, nucleic acid replication, diseases, vectors, and geographical distribution, among other characteristics.

Joe Galat

While returning to Montreal for his Daughter’s admission to McGill University in 1999, Galat was asked by John Gilman, founder and former Chief Executive Officer of FieldTurf, to help introduce the upstart company called FieldTurf, a replication of a grass sports field.

John Bramhall

Bramhall's A Just Vindication of the Church of England from the Unjust Aspersion of Criminal Schism (1654) was answered by the titular Bishop of Chalcedon, and Bramhall replied to this with Replication in 1656, where he prays that he might live to see the day when all Christian churches united again.

Molecular motor

Helicases separate double strands of nucleic acids prior to transcription or replication.

Multimaster

Multi-master replication, a method of replication employed by databases to transfer data or changes to data across multiple computers

Murder of Celia Douty

Dr Kary Mullis, who won a Nobel Prize for his work on DNA replication, advised the defence throughout the trial, but was not called to testify.

Nikolai Eberhardt

In the spirit of Julien Offray de La Mettrie (1709–1751) he derives understanding of humanity, including culture and religion, not from the evolutionary approach — which he does not oppose, but transcends — but from considering humans as self reproducing, intelligent bio-mechanical robots, or biobots.

Norovirus cis-acting replication element

In molecular biology, the Norovirus cis-acting replication element (CRE) is an RNA element which is found in the coding region of the RNA-dependent RNA polymerase in Norovirus.

Oglethorpe Plan

The same basic plan was intended for replication in towns throughout the colony; however, Darien, Georgia is the only other living town in which the original design has survived.

OpenLearn

The use of an open source virtual learning environment, along with the ability for people to download and upload materials in various formats (from an RSS to a print to an IMS Common Cartridge) encourages replication of the content and enables interoperability with other provider’s content management systems.

Podophyllotoxin

For instance, etoposide binds and stabilizes the temporary break caused by the enzyme, disrupts the reparation of the break through which the double-stranded DNA passes, and consequently stops DNA unwinding and replication.

Processivity

Because the binding of the polymerase to the template is the rate-limiting step in DNA synthesis, the overall rate of DNA replication during S phase of the cell cycle is dependent on the processivity of the DNA polymerases performing the replication.

R1 plasmid

CopA-like RNA, an antisense RNA involved in replication control of the plasmid.

Reverse-transcriptase inhibitor

RTIs inhibit activity of reverse transcriptase, a viral DNA polymerase that is required for replication of HIV and other retroviruses.

RK2 plasmid

PFF1 consists of an origin of replication, oriV, an origin of transfer, oriT, a gene coding for plasmid replication proteins, trfA, and two antibiotic resistance genes, bla and cat, which confer resistance to Ampicillin and Chloramphenicol, respectively.

SOS response

Activation of the SOS genes occurs after DNA damage by the accumulation of single stranded (ssDNA) regions generated at replication forks, where DNA polymerase is blocked.

Sporulation in Bacillus subtilis

Even then, certain conditions must be met such as chromosome integrity, the state of chromosomal replication, and the functioning of the Krebs cycle.

Ultimaker

Contrary to the non-commercial RepRap project founded By Adrian Bowyer, Ultimaker is not focused on an end-goal of self-replication.
