zero time control造句

• In an experiment to test incorporation of the amino acid Leucine, Karen Junge et all used two controls at-80癈 and-196癈, well below the eutectic freezing point of salt, and to their surprise, they found that the Colwellia psychrerythraea strain 34H was able to continue to incorporate low levels of Leucine right down to-196癈 . They hypothesize that the Leucine enters the cell boundaries at higher temperatures in the first few seconds of the experiment, then gets incorporated into the cell at lower temperatures ( it doesn't get incorporated right away as they proved through zero time controls ).
