Plasmids are naturally occurring, stable genetic elements found in bacteria, fungi, and even in the mitochondria of some plants. They may be composed of DNA or RNA, double-stranded or single-stranded, linear or...

Episomes, plasmids, insertion sequences, and transposons are elements of DNA (deoxyribonucleic acid) that can exist independent of the main, or genomic, DNA. An episome is a non-essential genetic element. In addition to its independent existence, an...

Plasmids are extra-chromosomal, covalently closed circular (CCC) molecules of double stranded (ds) DNA that are capable of autonomous replication. The prophages of certain bacterial phages and some dsRNA elements in yeast are also called plasmids, but...

A circular, double-stranded molecule of DNA, commonly found in bacteria. Plasmids are able to self-replicate in bacteria and often confer a useful property on them, such as resistance to antibiotics. Because of their high frequency of replication, and...

A circular piece of DEOXYRIBONUCLEIC ACID (DNA) located outside the chromosome and found in bacteria. Plasmids are used in genetic engineering as a vehicle to insert new genetic material into other micro-organisms or...

A plasmid is an extrachromosomal DNA molecule separate from the chromosomal DNA and capable of autonomous replication. In many cases, It is typically circular and double-stranded. It usually occurs naturally in bacteria, and is sometimes found in...
