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 ...
In prokaryotes, bidirectional replication initiates at one replicative origin on the circular chromosome and terminates at a site opposed from the initial start of the origin. [124] These termination regions have DNA sequences known as Ter sites. These Ter sites are bound by the Tus protein.
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.
Prokaryotic DNA Replication is the process by which a prokaryote duplicates its DNA into another copy that is passed on to daughter cells. [1] Although it is often studied in the model organism E. coli, other bacteria show many similarities. [2] Replication is bi-directional and originates at a single origin of replication (OriC). [3]
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.
Rolling circle replication (RCR) is a process of unidirectional nucleic acid replication that can rapidly synthesize multiple copies of circular molecules of DNA or RNA, such as plasmids, the genomes of bacteriophages, and the circular RNA genome of viroids. Some eukaryotic viruses also replicate their DNA or RNA via the rolling circle mechanism.
The US last dealt with a debt ceiling crisis in early 2023, when it hit its $31.4 trillion debt limit. After months of contentious negotiations between the GOP-led House and the Democrats who ...
