Answer:What do banding patterns indicate?
Banding patterns are patterns of light and dark transverse bands on chromosomes. The light and dark bands become apparent by staining the chromosome with a chemical solution and then viewed under a microscope. These bands describe the location of genes on a chromosome.
Explanation:
Why are banding patterns important?
Banding Patterns Reveal the Structural Details of Chromosomes. Without any treatment, structural details of chromosomes are difficult to detect under a light microscope.
What does each stained band represent?
bands are the horizontal "bars" which are actually stained DNA molecules embedded in the gel. As the DNA molecules migrate through the gel, they are sorted according to their molecular weight, so that each band represents DNA of a specific molecular weight.

The bacteria that you would not use a Gram stain on are Escherichia coli, Pseudomonas spp. and Clostridium spp, and Neisseria meningitidis.
<h3>
What are Gram stain negative bacteria?</h3>
Gram-negative bacteria have cell walls with thin layers of peptidoglycan and high lipid content.
This causes them to appear red to pink under a Gram stain.
<h3>Examples of Gram - negative bacteria</h3>
Gram-negative bacteria include:
- Pseudomonas,
- Klebsiella,
- Proteus,
- Salmonella,
- Providencia,
- Escherichia,
- Morganella,
- Aeromonas
- Citrobacter
- Neisseria meningitides
Thus, the bacteria that you would not use a Gram stain on are Escherichia coli, Pseudomonas spp. and Clostridium spp, and Neisseria meningitidis.
