A plasmid is a small, circular, double-stranded DNA molecule that is distinct from a cell's chromosomal DNA. Plasmids naturally exist in bacterial cells, and they also occur in some eukaryotes.

As mentioned, plasmids are double-stranded circular DNA segments. In order to pass through the thin tube that connects the bacteria, one of those circular strands is cut at a certain point by a ...

The coordinated termination of DNA replication is an important step in the life cycle of bacteria with circular chromosomes, but has only been defined at a molecular level in two systems to date.

Three students from Centreville High School in Clifton discovered a potentially harmful substance – DNA residues, or tiny ...

Recent TAU study demonstrates how a crucial but underexplored process of DNA transfer between bacteria affects its defense ...
