Thus, only regions of DNA adjacent to an integrated phage can be transferred by this method. Spheroplast Partial removal of the cell wall resulting in osmotically sensitive cells. A mutation that occurs without known exposure to a mutagen. Spore A highly resistant, resting state of an organism. Under the proper condiditons s spore will germinate to form a viable, reproducing organism.
Bacterial spores are often very resistant to heat and dessication.
The most common start codon is AUG but sometimes GUG or rarely UUG can be used as a start codon. For example, resulting from digestion with a Class II restriction endonuclease. Strain An organism that is different from other organisms of the same species due to genetic differences. An antibiotic that inhibits protein synthesis in bacteria by binding to the S12 protein of the 30s ribosomal subunit and inhibiting translation. Only mutant ribosomes are Str R , so resistance to streptomycin is recessive to streptomycin sensitivity.
