In particular, these sites are made competent to initiate replication by loading of the Mcm replicative helicase prior to the start of S phase; thus, 'a site that binds Mcm in G1' might be considered to provide an operational definition of a replication origin. By fusing a subun...

During each cell division, a human cell will replicate ~2 m of DNA within the S-phase time constraints. To achieve this, DNA replication initiates from thousands of regions that are called DNA replication origins and are spread across the genome. The positioning of DNA replication initiation ...

The Individualism–Collectivism Trait.In the present paper, we follow the conventional definition of culture in economic research as “decision making heuristics or ’rules of thumb’ that have evolved given our need to make decisions in complex and uncertain environments” (Nunn,2012, p. S109)....
Water is essential for life as we know it, but it has paradoxically been considered inimical to the emergence of life. Proteins and nucleic acids have sustained evolution and life for billions of years, but both are condensation polymers, suggesting that
Many people have reached out to me questioning the assertion I have been making since early 2020 that “the most likely starting point of the coronavirus crisis is an accidental leak from one of the Chinese virology institutes in Wuhan” (see this CNN interview, this Newsweek editorial, this ...
(9 families) have small circular genomes, which are known or predicted to be replicated by the rolling-circle mechanism. This mechanism of replication is initiated by the virus-encoded Rep protein of the HUH endonuclease superfamily, characterized by the signature HUH motif, in which two histidine...
In some instances, political leaders extend analogies by implying that current events could potentially lead to a replication of past successes or mistakes. For example, during the Gulf War, political leaders in the United States who drew an analogy between Saddam Hussein and Adolph Hitler implied ...
