Chromosome Replication02:31

Chromosome Replication

10.5K
Before a cell can divide, it must accurately replicate all of its chromosomes, including the DNA and its associated histone and non-histone proteins.  This process begins at numerous origins of replication during the S phase of the cell cycle in each of a cell’s chromosomes simultaneously. Certain nucleotides can act as origins of replication, but these sequences are not well defined - especially in complex, multi-cellular, eukaryotic species. The length of DNA that spans an origin...

DNA Replication02:40

DNA Replication

59.0K
DNA replication involves the separation of the two strands of the double helix, with each strand serving as a template from which the new complementary strand is copied.  After replication, each double-stranded DNA includes one parental or “old” strand and one “new” strand. This is known as semiconservative replication. The resulting DNA molecules have the same sequence and are divided equally into the two daughter cells.

Replication in Prokaryotes

27.7K
DNA replication has three main steps: initiation, elongation, and termination. Replication in prokaryotes begins when initiator proteins bind to the single origin of replication (ori) on the cell's circular chromosome. Replication then proceeds around the entire circle of the chromosome in each direction from the two replication forks, resulting in two DNA molecules.

The DNA Replication Fork01:02

The DNA Replication Fork

40.6K
An organism’s genome needs to be duplicated in an efficient and error-free manner for its growth and survival. The replication fork is a Y-shaped active region where two strands of DNA are separated and replicated continuously. The coupling of DNA unzipping and complementary strand synthesis is a characteristic feature of a replication fork.   Organisms with small circular DNA, such as E. coli, often have a single origin of replication; therefore, they have only two replication...

Area of Science:

  • Psychology
  • Behavioral Science
  • Scientific Methodology

Background:

  • Replication failures in psychological science have prompted significant reforms.
  • These reforms have led to improvements in research standards and methodologies.

Purpose of the Study:

  • To evaluate the impact of replication failures on scientific reform.
  • To discuss the future of replication studies in science.

Main Methods:

  • Analysis of the impact of replication failures on scientific standards.
  • Description of different types of replication strategies.

Main Results:

  • Massive, multi-lab replication projects have fulfilled their purpose and are expected to decline.
  • New forms of replication, including "friendly" and "adversarial" approaches, are emerging.

Conclusions:

  • The era of large-scale replication projects appears to be concluding.
  • Continued use of diverse replication methods, including "friendly" and "adversarial" replications, will be valuable for scientific progress.
