A Tn 10-lacZ-kanR-URA3 Gene Fusion Transposon for Insertion Mutagenesis and Fusion Analysis of Yeast and Bacterial Genes.

... We describe here a new variant of transposon TnlO especially adapted for transposon analysis of cloned yeast genes; it can equally well be used for analysis of prokaryotic genes. We have applied this element to analysis of the LEU2, RADSO, and CDC48 genes of Saccharomyces cerevisiae. This transposon ...

Epigenetics in learning and memory

While the cellular and molecular mechanisms of learning and memory have long been a central focus of neuroscience, it is only in recent years that attention has turned to the epigenetic mechanisms behind the dynamic changes in gene transcription responsible for memory formation and maintenance. Epigenetic gene regulation often involves the physical marking (chemical modification) of DNA or associated proteins to cause or allow long-lasting changes in gene activity. Epigenetic mechanisms such as DNA methylation and histone modifications (methylation, acetylation, and deacetylation) have been shown to play an important role in learning and memory.
