AAB MT Molecular Diagnostics Enzymes Questions And Answers Rated A+. EcoR1, HindIII, BamHI, NotI, and PacI are all examples of which class of restriction enzymes? - correct answer. Class II This class of restriction enzymes account for at least 90% of enzymes used in molecular biology? - correct answer. Class IIP (Palindromic specificity) How many base pairs are normally recognized by Class II restriction enzymes? - correct answer. 4-8 base pairs (6-8 allows for larger fragments) This restriction enzyme class typically recognizes modified (methylated) DNA? - correct answer. Class IV This enzyme degrades ssDNA from either the 5' or 3' end? - correct answer. Exonuclease VII This enzyme is one of the few enzymes that has 5' exonuclease activity? - correct answer. Exonuclease VII What is the enzyme that cleaves the extra nucleotides from the 5' end of a tRNA precursor. Most forms of bacterial RNase P have a catalytic RNA subunit? - correct answer. RNase P (Ribonuclease P) What is the enzyme that synthesizes DNA by linking together deoxynucleoside monophosphates (dNMPs) in the order dictated by the complementary sequence of nucleotides in a template DNA strand? - correct answer. DNA polymerase What is the enzyme that cleaves other proteins? - correct answer. Protease What is the enzyme that degrades RNA? - correct answer. RNase (Ribonuclease)
