Label the descriptions as prokaryotic (P) and eukaryotic (E).
Pro
- •No nucleus.
- •No unit membrane bound organelles.
- •Smaller.
- •Circular DNA
- Bacteria and Archaea
Euk
- •Nucleus.
- •Unit membrane bound organelles.
- •Larger.
- •Double stranded helix DNA.
- •Protists, Animals, Plants, Fungi.
- •YOU are eukaryotic.
There are more bacterial cells living on your body than there are total number of cells that make up
the whole body
Give three examples of bacteria being helpful
- Environmental applications include cleaning up oil spills, breaking down toxic wastes and herbicides, and in the production of biodegradable plastics.
- Recently the species Thiobacillus ferrooxidans has been used in gold and copper mining and initiated a new industry known as biomining.
- In medicine, some are used as antibiotics.
What is the basis of antibiotic resistance in pathogenic bacteria as well as the evolution of prokaryotes
Recombination (horizontal gene transfer)
Why was the Kingdom Monera split into two distinct domains (Bacteria and Archaea)?
•based on RNA sequencing technology.
