Question
Which one of the following has a catalytic RNA?(A) Ribonuclease H(B) Ribozyme(C) RNA polymerase I(D) RNA polymerase IIQ.10 The number of significant figures in a reported measurement of 0.00361 is(A) 3(B) 4(C) 5(D) 6
Solution
The answer to the first question is (B) Ribozyme. Ribozymes are RNA molecules that have the ability to catalyze specific biochemical reactions, similar to the action of protein enzymes.
The answer to the second question is (B) 4. The number of significant figures in a reported measurement of 0.00361 is 4. The leading zeros are not counted as significant figures. The first significant figure starts with the first non-zero digit, which in this case is 3. So, the significant figures are 3, 6, and 1.
