concatemer

(kon-kat'ah-mĕr),
One of two or more DNA or RNA molecules that are covalently joined (end to end) in the same orientation.

concatemer

a composite DNA MOLECULE, comprising two or more identical molecules joined together. Often BACTERIOPHAGE GENOMES are presented as concatemers for packaging into CAPSIDS during phage aassembly

Rolling circle replication in solution was developed to form billions of discrete DNA nanoballs (DNBs), each comprising a concatemer with approximately 500 copies of the original circle.
However, deletions extending into regions adjacent to the transgene concatemer are not detected, as two intact cos sites are required for the packaging of a single [lambda] vector.
Concatemer sequences were analyzed by using SAGE software (version 4.
With the magnetic induction intensity of external magnetic field increasing, the linear extent of flocculation grows obviously by developing from dimers or triplets into concatemers with the occurrence of branched chains.

Briefly, DNA fragments were repaired to blunt-ended DNA by fill-in and exonuclease after A-tailing was conducted to prevent the formation of adapters, dimers, and concatemers.
A ladder ofbacteriophage lambda concatemers (New England Biolabs) was used as molecular weight markers.
Concatemers of the e phage DNA ladder (Promega, Madison, WI, USA) starting at 48.
Lambda DNA concatemers (New England BioLabs) were used as molecular size markers.
In addition, the PCR products were also analyzed by agarose gel electrophoresis to test for concatemers and the correct product size of 425 bp.
