Objective:
The objective of the research presented here was to determine whether autonomous replication sequences (ARS) discovered in the eccDNA replicon of glyphosate resistant Amaranthus palmeri enable self-replication in a yeast system.
Results:
Sequence analysis of the eccDNA replicon revealed a region of sharp changes in A + T/G + C content with characteristic bending indicative of an autonomous replication sequence. Further sequence analysis revealed an extended autonomous replication sequence (EACS) in close proximity to multiple DNA unwinding element (DUE) sequences. This region of the eccDNA replicon enabled autonomous replication of an ARS-less yeast plasmid.

Chromosome Structure
The centromere is a DNA sequence that links sister chromatids. This is also where kinetochores, protein complexes to which spindle microtubules attach, are constructed after the chromosome is replicated. The kinetochores allow the spindle microtubules to move the chromosomes within the cell during cell division.

The Replisome
The synthesis of the leading and lagging strands is a highly coordinated process. To explain this, the “Trombone model” was proposed by Bruce Alberts in 1980. The DNA loop formation starts when a primer is synthesized on the parent lagging strand. The loop grows with...
