Criteria

Bacterial chromosome

Bacterial plasmid

Number
  • Only one chromosome in bacteria.
  • Chromosomes have several thousand genes.
  • Variable number of plasmid.
  • Plasmids have a small number of genes.

Type of genes present
  • A plasmid is a small, circular,double stranded DNA molecule.
  • Plasmids can contain the following types of genes:-

antibiotic resistance genes, transgenes and reporter genes
  • The bacterial chromosome is one long, single molecule of double stranded, helical, supercoiled DNA.

Purpose/function
  • Chromosomes are essential to cell function being the genetic information carrier.
  • Chromosomal DNA provides all the information for regular well being of bacteria
  • Plasmids give extra survival to host bacteria.
  • Plasmids are used as gene carriers to an alien cell. Hence it can be applied in genetic engineering.
  • plasmids provide bacteria with genetic advantages, such as antibiotic resistance.

Experiment 2: Cloning a DNA Fragment to a Bacterially-Derived Plasmid Vector Bacteria frequently contain extrachromosomal plasmids, which are circular DNA genetic elements that are self-replicating. Plasmids are typically not necessary for the bacteria's survival but can sometimes confer a growth advantage to the bacteria. Plasmids can be transferred between bacteria and recombinant DNA technology makes use of this feature to introduce “foreign” genes into bacteria and use the bacteria as a cell “factory” to produce the gene. Genes are inserted...
