Question 3. It is not necessary to take precautions against shearing RNA during the purification procedure because: a. RNA is stronger than DNA. b. RNA is isolated in a buffer that protects against physical shearing. c. The uracil in RNA causes RNA to resist shearing. d. The protein associated with RNA protects against shearing. e. RNA molecules are primarily single stranded, smaller, and more flexible than DNA molecules.
