A genetic study of a Staphylococus aureus plasmid involving cure and transference

open access: yesSão Paulo Medical Journal
High frequency transfer and elimination of drug resistance may indicate an extrachromosomal inheritance of genetic determinants. This study shows the cure and transfer of a small plasmid and tetracycline resistance in Staphylococcus aureus 1030 (55)TetR ...

Gene therapy:the potential applicability of gene transfer technology to the human germline [PDF]

open access: yes, 2004
The theoretical possibility of applying gene transfer methodologies to the human germline is explored. Transgenic methods for genetically manipulating embryos may in principle be applied to humans.

Enhancer sharing promotes neighborhoods of transcriptional regulation across eukaryotes [PDF]

open access: yes, 2016
Enhancers physically interact with transcriptional promoters, looping over distances that can span multiple regulatory elements. Given that enhancer–promoter (EP) interactions generally occur via common protein complexes, it is unclear whether EP pairing

Transformation of \u3cem\u3eTetrahymena thermophila\u3c/em\u3e with Hypermethylated rRNA Genes [PDF]

open access: yes, 1988
The extrachromosomal rRNA genes (rDNA) of Tetrahymena thermophila contain 0.4% N6-methyladenine. C3 strain rDNA was isolated, hypermethylated in vitro, and microinjected into B strain host cells. Clonal cell lines were established, and transformants were

The evolutionary dynamics of extrachromosomal DNA in human cancers

open access: yesNature Genetics, 2022
Oncogene amplification on extrachromosomal DNA (ecDNA) is a common event, driving aggressive tumor growth, drug resistance and shorter survival. Currently, the impact of nonchromosomal oncogene inheritance—random identity by descent—is poorly understood.

Maloethanolic deacidification of high acid juices during wine yeast alcoholic fermentation : a thesis presented in partial fulfilment of the requirements for the degree of Master of Science in Microbiology at Massey University [PDF]

open access: yes, 1996
Malic acid is a major acid found in grapes. In countries with cooler climates, such as New Zealand, this acid is not fully respired from grapes and will impart a sour taste on grape juices.
