concatemer

Link these small pieces of sequence together to form a long chain (or concatemer).

The end of the concatemer is cut a specific site called the pac site or packaging site.

The rest of the concatemer that does not fit into one head is separated and the machinery begins packing this into a new head.

This results in numerous copies of the genome being present on a single linear DNA molecule called a concatemer.

When packaged, the concatemer is cut at unspecific positions of the same length, leading to several genomes that represent circular permutations of the original.

Ribozymes have been shown to be involved in the viral concatemer cleavage that precedes the packing of viral genetic material into virions.

The T4 genome is terminally redundant and is first replicated as a unit, then several genomic units are recombined end-to-end to form a concatemer.

Notably, this doesn't release single copies of the phage genome, but rather one long molecule with many copies of the genome: a concatemer.

Another consequence of the DNA being cut out of a concatemer is that a given linear molecule can start at any location on the circular genome.

A concatemer is a long continuous DNA molecule that contains multiple copies of the same DNA sequences linked in series.

Continued DNA synthesis can produce multiple single-stranded linear copies of the original DNA in a continuous head-to-tail series called a concatemer.

As an example, if the genes in the phage DNA are arranged ABC, then in a concatemer the genes would be ABCABCABCABC and so on.
