  2. Bi-directional hypothesis of language and action - Wikipedia

    en.wikipedia.org/wiki/Bi-directional_hypothesis...

    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 ...

  3. Circular chromosome - Wikipedia

    en.wikipedia.org/wiki/Circular_chromosome

    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.

  4. Prokaryotic DNA replication - Wikipedia

    en.wikipedia.org/wiki/Prokaryotic_DNA_replication

    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]

  5. Probabilistic epigenesis - Wikipedia

    en.wikipedia.org/wiki/Probabilistic_epigenesis

    Probabilistic epigenesis is a way of understanding human behavior based on the relationship between experience and biology. [1] It is a variant form of epigenetics, proposed by American psychologist Gilbert Gottlieb in 1991. [1]

  6. Rolling circle replication - Wikipedia

    en.wikipedia.org/wiki/Rolling_circle_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.

  7. Theta structure - Wikipedia

    en.wikipedia.org/wiki/Theta_structure

    Two replication forks can proceed independently around the DNA ring and when viewed from above the structure resembles the Greek letter "theta" (θ). [ 1 ] [ 2 ] Originally discovered by John Cairns , it led to the understanding that (in this case) bidirectional DNA replication could take place.

  8. Eukaryotic DNA replication - Wikipedia

    en.wikipedia.org/wiki/Eukaryotic_DNA_replication

    Eukaryotic DNA replication. Eukaryotic DNA replication is a conserved mechanism that restricts DNA replication to once per cell cycle. Eukaryotic DNA replication of chromosomal DNA is central for the duplication of a cell and is necessary for the maintenance of the eukaryotic genome.

  9. DNA replication - Wikipedia

    en.wikipedia.org/wiki/DNA_replication

    Progress of replication forks is inhibited by many factors; collision with proteins or with complexes binding strongly on DNA, deficiency of dNTPs, nicks on template DNAs and so on. If replication forks get stuck and the rest of the sequences from the stuck forks are not copied, then the daughter strands get nick nick unreplicated sites.
