transfer RNA

300

Cut DNA at specific, often palindromic, sequences

Are thought to be a defense mechanism bacteria use against bacteria-infecting viruses

Recognize sequences that are not in the genome of the bacteria from which they originate

Describes what enzyme?

Restriction endonuclease

300

The cycle number at which a sample reaches a preset level of fluorescence is called the ____________

cycle threshold
