How do bacteria become resistant to antibiotics Khan Academy?
Transposable elements are chunks of DNA that “jump” from one place to another. They can move bacterial genes that give bacteria antibiotic resistance or make them disease-causing.
What are bacteria archaea and protists?
Bacteria, protists, and archaea belong to the world of microbes-mostly unicellular organisms. Bacteria are prokaryotes, organisms with DNA that is not enclosed within a nucleus, whereas protists are eukaryotes, organisms with a bounded nucleus. Along with archea, they were the earliest forms of life on the planet.
What is biology library?
