A comparison of different phytoplasma DNA extraction methods using competitive PCR

open access: yesPhytopathologia Mediterranea, 2001
The primer pair 16endF-Tmod, specific for the16S/23S rDNA spacer region, amplifies different length fragments when the target DNA belongs to phytoplasmas of the X-clade and AP-clade in compared with phytoplasmas of the AY-clade. The cloned 16S/23S spacer

Alignment of nucleosomes along DNA and organization of spacer DNA inDrosophilachromatin

open access: yesNucleic Acids Research, 1982
A series of mono- and dinucleosomal DNAs characterized by an about ten-base periodicity in the size were revealed in the micrococcal nuclease digests of Drosophila chromatin which have 180 +/- 5 base pair (bp) nucleosomal repeat. 20, 30, and 40 bp spacers were found to be predominant in chromatin by trimming DNA in dinucleosomes to the core position ...

Optimal number of spacers in CRISPR arrays

open access: yes, 2017
We estimate the number of spacers in a CRISPR array of a bacterium which maximizes its protection against a viral attack. The optimality follows from a competition between two trends: too few distinct spacers make the bacteria vulnerable to an attack by ...

NUMBER AND HETEROGENEITY OF rRNA OPERONS IN RUMEN BACTERIAL MEMBERS FROM THE GENUS Prevotella

open access: yesActa Agriculturae Slovenica, 1998
The number of rRNA operons and internal spacer region heterogeneities in members of the rumen genus Prevotella were analysed. Chromosomal DNA from 20 strains belonging to P.ruminicola, P.albensis, P.bryanti and P.brevis was isolated, digested by five ...

The physicist's guide to one of biotechnology's hottest new topics: CRISPR-Cas

open access: yes, 2018
Clustered regularly interspaced short palindromic repeats (CRISPR) and CRISPR-associated proteins (Cas) constitute a multi-functional, constantly evolving immune system in bacteria and archaea cells.
