2010年2月8日 · Emerging models of the bacterial nucleoid show that nucleoid-associated proteins (NAPs) and transcription contribute in combination to the dynamic nature of nucleoid structure. NAPs and...

First elucication of the detailed structure of a bacterial nucleoid. Left and right replichores of Caulobacter are each organized as a radial array of presumptive plectoneme loops enforced by nucleoid protein HU and longitudinally compacted by SMC.

A bacterial genomic DNA resides inside cells in a highly condensed and functionally organized form called nucleoid (nucleus-like structure without a nuclear membrane). The Escherichia coli chromosome or nucleoid is composed of the genomic DNA , RNA , and protein .

2017年4月28日 · The nucleoid is the space within a prokaryotic cell where the genetic information, called the genophore, is found. Prokaryotes are divided into bacteria and archaea, which are both unicellular organisms that contain no membrane-bound organelles.

Emerging models of the bacterial nucleoid show that nucleoid-associated proteins (NAPs) and transcription contribute in combination to the dynamic nature of nucleoid structure. NAPs and other DNA-binding proteins that display gene-silencing and anti-silencing activities are emerging as key antagonis …

2005年10月15日 · Recent advances in bacterial cell biology have revealed unanticipated structural and functional complexity, reminiscent of eukaryotic cells. Particular progress has been made in understanding the structure, replication, and segregation of the bacterial chromosome.

2004年4月1日 · As in eukaryotes, bacterial chromosomal DNA is highly compacted to form a nucleus-like structure, termed the nucleoid. Replication, segregation, transcription and translation — in the absence of a nuclear membrane — can occur simultaneously in bacterial cells. However, these processes clearly need to be highly controlled and well coordinated.

2024年10月7日 · Nucleoid Structure. The nucleoid region is a fascinating aspect of bacterial cells, characterized by its dynamic and adaptable nature. Unlike the rigid structure of a eukaryotic nucleus, the nucleoid is a more fluid entity, allowing for efficient cellular processes.

A bacterial genome typically comprises a single circular DNA molecule, usually between 1.5 and 10 Mbp in free-living bacteria [4,5], which in vivo is packaged with proteins into a distinct structure known as the bacterial nucleoid. The information encoded in one bacterial genome directs all functions necessary to maintain a functional and self ...
