Although most prokaryotes cannot survive in nature without their cell walls, some do so naturally. These include the mycoplasmas, a group of pathogenic bacteria that causes several infectious...
Plasmids are extra-chromosomal genetic elements that replicate independently. They are small, circular (some are linear), double-stranded DNA molecules (mostly) that exist in bacterial cells and some...
Gram stain is the most important staining procedure in Microbiology. Most bacteria can be broadly classified as Gram-positive or Gram-negative. Gram-positive bacteria stain purple, whereas...
The term peptidoglycan was derived from the peptides and the sugars (glycan) that make a molecule; it is also called 'murein' or 'mucopeptide.' This complex interwoven network of sugar polymer and...
Transposons are mobile genetic elements that are found in almost all organisms. Scientists believe that transposons make up more than 40% of the human genome. They are also referred to as ‘jumping...
