Welcome back Diamond — missed you this week. 1. a) A plasmid is a small, extrachromosomal DNA molecule within a cell that is physically separated from chromosomal DNA and can replicate independently. They are typically found in bacteria and archaea, and sometimes in eukaryotic organisms. Plasmids often carry genes that provide bacteria with genetic advantages, such as antibiotic resistance.
