Which of these statements is true for restriction enzymes? each restriction enzyme is able to make a staggered cut at its recognition site. a given restriction enzyme will always recognize the same dna sequence, but it will cut differently depending on the species of origin of the dna. a different restriction enzyme must be used to open the vector dna than to excise the gene sequence to be cloned. any restriction enzyme can cut any piece of dna. restriction enzymes are useful in genetic engineering when they make staggered cuts in dna?

the relative atomic mass of an element is the mass of one atom of that element, relative to 1/12th of the mass of a  1212c atom. to convert to an absolute mass in kg, it is necessary to multiply by  1.661×10−271.661×10−27.

the relative atomic mass is roughly equal to the number of neutrons, plus the number of protons, in the nucleus of the atom.

for elements with more than one stable isotope (different types of nucleus with different numbers of neutrons but the same number of protons), the quoted mass is usually the average mass, weighted by the relative abundance of the different isotopes.

answer; the above statement/question is (false);
