In engineering , science , and statistics , replication is the repetition of an experiment al condition so that the variability associated with the phenomenon can be estimated. ASTM , in International standard standard E1847, defines replication as the repetition of the set of all the treatment combinations to be compared in an experiment. Each of the repetitions is called a replicate . Replication is not the same as repeated measurement s of the same item they are dealt with differently in statistical experimental design and data analysis . For proper Sampling statistics sampling , a process or batch of products should be in reasonable statistical control inherent random variation is present but variation due to assignable special causes is not. Evaluation or testing of a single item does not allow for item to item variation and may not represent the batch or process. Replication is needed to account for this variation among items and treatments. Example As an example, consider a continuous process which produces items. Batches of items are then processed or treated. Finally, tests or measurements are conducted. Several options might be available to obtain ten test values. Some possibilities are One finished and treated item might be measured repeatedly to obtain ten test results. Only one item was measured so there is no replication. The repeated measurements help identify observational error . Ten finished and treated items might be taken from a batch and each measured once. This is not full replication because the ten samples are not random and not representative of the continuous nor batch processing. Five items are taken from the continuous process based on sound statistical sampling. These are processed in a batch and tested twice each. This includes replication of initial ... twice each.

Refimprove date December 2009 The replication factor C , or RFC, is a five subunit ref MeshName Replication Protein C ref protein complex that is required for DNAreplication . The Protein subunit subunits of this heteropentamer are named RFC1 Rfc1 , RFC2 Rfc2 , RFC3 Rfc3 , RFC4 Rfc4 , and RFC5 Rfc5 in S. cerevisiae . RFC is used in eukaryotic replication as a clamp loader, similar to the Complex in E. coli . Its role as clamp loader involves catalysing the loading of Proliferating Cell Nuclear Antigen PCNA on to DNA. It binds to the 3 end of the deoxyribonucleic acid DNA and uses ATP to open the ring of PCNA so that it can encircle the DNA. ATP hydrolysis causes release of RFC, with concomitant clamp loading onto DNA. References Reflist DNAreplication DEFAULTSORT Replication Factor C Category DNAreplication Protein stub ... more details

Rolling circle replication describes a process of unidirectional nucleic acid replication that can rapidly synthesize multiple copies of circular molecules of DNA or RNA , such as plasmid s, the genome s of bacteriophage s, and the circular RNA genome of viroid s. Some eukaryotic viruses also replicate their DNA via a rolling circle mechanism. Circular DNAreplication Rolling circle DNAreplication is initiated by an initiator protein encoded by the plasmid or bacteriophage DNA, which nicks one strand of the double stranded, circular DNA molecule ... biology primer for DNA synthesis by DNA polymerase III . Using the unnicked strand as a template, replication proceeds around the circular DNA molecule, displacing the nicked strand as single stranded DNA. Displacement of the nicked strand is carried out by a host encoded helicase called PcrA the abbreviation standing for plasmid copy reduced in the presence of the plasmid replication initiation protein. Continued DNA synthesis can produce multiple single stranded linear copies of the original DNA in a continuous head to tail series called a concatemer . These linear copies can be converted ... more details
