LIFE SCIENCE

Detailed explanation-1: -The bacterial plasmid contains DNA as genetic material, replicating independently and comprising antibiotic-resistant genes. Many antibiotic-resistant genes in bacteria are present in plasmids.

Detailed explanation-2: -At their most basic level, plasmids are small circular pieces of DNA that replicate independently from the host’s chromosomal DNA. They are mainly found in bacteria, but also exist naturally in archaea and eukaryotes such as yeast and plants.

Detailed explanation-3: -Plasmids are self-replicating extrachromosomal DNA molecules found in Gram-negative and Gram-positive bacteria as well as in some yeast and other fungi. Although most of them are covalently closed circular double-stranded DNA molecules, recently linear plasmids have been isolated from different bacteria.
