Plasmid - Definition, Types and Functions - Biology Dictionary
2019年4月7日 · A plasmid is a small, circular piece of DNA that is different than the chromosomal DNA, which is all the genetic material found in an organism’s chromosomes. It replicates independently of chromosomal DNA.
Plasmid Biology | Wiley Online Books
2004年4月5日 · Details basic biological processes such as replication and inheritance functions, specific plasmid systems, plasmid evolution, and use of plasmids as genetic tools. Covers use of genomic approaches for the study of plasmid biology, and presents a review of plasmids from bacteria, archaea, and eukaryotes.

3 天之前 · A plasmid is a small circular DNA molecule found in bacteria and some other microscopic organisms. Plasmids are physically separate from chromosomal DNA and replicate independently. They typically have a small number of genes — notably, some associated with antibiotic resistance — and can be passed from one cell to another.
Plasmids - Definition, Structure, Functions, Examples - Biology …
2024年4月6日 · Plasmids are small, extrachromosomal DNA structures found primarily within bacterial cells, distinct from the primary chromosomal DNA. Unlike the chromosomal DNA that encompasses the essential genetic blueprint of the organism, plasmids are typically circular and replicate autonomously.
Plasmid | DNA replication, genetic engineering, cloning | Britannica
2025年1月19日 · plasmid, in microbiology, an extrachromosomal genetic element that occurs in many bacterial strains. Plasmids are circular deoxyribonucleic acid (DNA) molecules that replicate independently of the bacterial chromosome.
Plasmids- Definition, Properties, Structure, Types, Functions, …
2022年3月13日 · Plasmids are small circular DNA fragments, double-stranded, self-replicating extra chromosomal structures found in many microorganisms. The term Plasmid was coined by Joshua Lederberg in 1952. Plasmids are important as genetic tools, which are used to introduce, manipulate or delete certain genes from the host cell.
