Further research shows that the purified happyase* used in the first two experiments was actually contaminated with a reversible inhibitor called anger. when anger is carefully removed from the happyase* preparation, and the two experiments repeated, the measured increases to 4.8 µm s−1, and the measured km is now 15 µm.

interphase   is the cell cycle stage in which the cell acquires nutrients, creates and uses proteins and other molecules and starts the process of cell division by replicating the dna. it is the longest stage in the eukaryote cell cycle.

the following   can go wrong during interphase:   a base pair could be mismatched during the duplication process causing a mutation.   correct answer: c

explanation:

sand 60

clay 10

silt 30

sandy loam should be dominated by the sand. as the amount of sand increased, the amount of slit needed to anchor the plants' roots to the sand will also be increased. even though the amount is very little, 10% part of clay is still necessary for proper oxidation.
