A plasmid is a small, circular ... the genes carried in plasmids provide bacteria with genetic advantages, such as antibiotic resistance. Plasmids have a wide range of lengths, from roughly ...

John Innes Center researchers and partners used a model plasmid called RK2 that is used ... plasmids in their host and re-sensitize them to antibiotics." The study solves a decades-long conundrum ...

The word “episome” would later be replaced by a synonym, “plasmid.” Scientists now recognize plasmids as a major mechanism for transferal of antibiotic-resistance genes—sometimes whole ...

Antibiotic resistance is the ability of bacteria to resist ... The recent emergence and spread of a plasmid-encoded, transferable colistin resistance gene, mcr-1, is a cause for concern. The mcr-1 ...

In this article, we discuss transformation, bacterial transformation in particular, and how scientists can utilize it to ...

In the microscopic world of bacteria, gene transfer is a powerful mechanism that can alter cellular function, drive ...

Plasmid vectors can be used to clone, transfer, and manipulate genes. Often, these plasmids carry a gene for antibiotic resistance, which means that researchers can select for cells that are ...

However, plasmid copy numbers can fluctuate, causing inconsistent gene expression within bacterial populations. By balancing CRISPR-Cas-mediated cutting and gene transfer, ADEPT dynamically ...

In step 2, the gene fragment is integrated into a circular piece of DNA, called a plasmid, which is the main delivery vehicle into the cell and contains an antibiotic resistance gene for plasmid ...
