Which of the following checks dna for errors?
o a. dna fingerprinting
o b. dna polymerase
o c. gel electrophoresis
o d. restriction endonuclease

i think it would be b. tissue because an organ system is a group of organs that work together to perform one or more functions. each does a particular job in the body, and is made up of certain tissues.

i think its control and coordinate because im pretty sure thats what tissue does and the joints are what control movement and then your skeletal/ bones provides portection. hope that .
