Although studied in a unidirectional manner for many years, the bi-directional hypothesis was first described and tested in detail by Aravena et al. [1] These authors utilized the Action-Sentence Compatibility Effect (ACE), a task commonly used to study the relationship between action and language, to test the effects of performing simultaneous ...
When viewed from above, the replication of circular DNA looks like the Greek letter θ. A theta structure is an intermediate structure formed during the replication of a circular DNA molecule. Two replication forks can proceed independently around the DNA ring and when viewed from above the structure resembles the Greek letter "theta" (θ).
The initiator is the protein that recognizes the replicator and activates replication initiation. [1] Sometimes in bacteriology, the term "replicon" is only used to refer to chromosomes containing a single origin of replication and therefore excludes the genomes of archaea and eukaryotes which can have several origins. [2]
Relational frame theory argues that the building block of human language and higher cognition is relating, i.e. the human ability to create bidirectional links between things. It can be contrasted with associative learning , which discusses how animals form links between stimuli in the form of the strength of associations in memory.
During the elongation phase of replication, the enzymes that were assembled at oriC during initiation proceed along each arm of the chromosome, in opposite directions away from the oriC, replicating the DNA to create two identical copies. This process is known as bidirectional replication.
The authors emphasized that the findings reflect a problem that affects all of science and not just psychology, and that there is room to improve reproducibility in psychology. In 2021, the project showed that of 193 experiments from 53 top papers about cancer published between 2010 and 2012, only 50 experiments from 23 papers could be replicated.
Tesla and X CEO Elon Musk spent over a quarter of a billion dollars to help get President-elect Donald Trump back in the White House, according to newly released campaign finance records. The ...
In S phase, the Mcm2-7 complex interacts with helicase cofactors Cdc45 and GINS to isolate a single DNA strand, unwind the origin, and begin replication down the chromosome. In order to have bidirectional replication, this process happens twice at an origin. Both loading events are mediated by one ORC via an identical process as the first. [34]
