The seventh row of the periodic table of the elements was completed in 2010 as a result of a high-energy nuclear synthesis experiment that succeeded in creating a few nuclei of element 117.

"These are milestones in the pathways, and if we are able to find the milestones, we will understand how they are produced — how nuclear synthesis proceeds, step by step, from the iron to the superheavy elements," says Sidney Gales, director of the Institute for Nuclear Physics in Orsay, near Paris.

These are inevitably produced in relatively large amounts during the nuclear synthesis and often favor the +3 state.

Californium can also be used in nuclear synthesis of higher mass elements; ununoctium (element 118) was synthesized by bombarding californium-249 atoms with calcium-48 ions.

Such extracts from Xenopus UFE have provided the first non viral cell-free system able to faithfully reproduce nuclear synthesis events, from the replication of DNA to the assembly and reconstitution of a functional nucleus [24], [25] and either low- or high- speed extracts can be obtained, depending on the mechanism to be analyzed or the question to be addressed [26], [27].

It is preceded by a period called G1 (meaning "first gap") and followed by a period called G2, during which nuclear DNA synthesis does not occur.

However, although there are many reports of proteins stimulating the activity of RNA polymerase II in vitro6 11, no conclusive evidence has yet been obtained to show that these proteins are, in fact, functioning in the process of nuclear RNA synthesis.
