When a region of DNA must be repaired by removing and replacing some of the nucleotides, what ensures that the new nucleotides are in the correct sequence?

#SCPH05 I Biotechnology

  1. DNA cannot be repaired and this explains why mutations occur.

  2. The new nucleotides base pair accurately with those on the complementary strand.

  3. The repair enzyme recognizes the removed nucleotide and brings in an identical one to replace it.

  4. The three-dimensional structure determines the order of nucleotides.

An enzyme-catalyzed reaction was carried out with the substrate concentration initially a thousand times greater than the Km for that substrate.  After 9 minutes, 1% of the substrate had been converted to product, and the amount of product formed in the reaction mixture was 12 micromol.  If, in a separate experiment, one-third as much enzyme and twice as much substrate had been combined, how long would it take for the same amount (12 micromol) of product to be formed?
