The numerically first of these enzymes binds to a non-enzymatic substrate to form maturation-promoting factor, which moves the cell through the G2/M checkpoint. For 10 points each:
[10m] Name these serine/threonine kinases. They bind to a similarly named substrate to initiate the pathway that allows the cell to progress through checkpoints during mitosis.
ANSWER: cyclin-dependent kinases [or CDKs; accept CDK1; reject “cyclins”]
[10e] Kinases like CDKs enable signal transduction by transferring these ions from one molecule to another. ATP contains three of these ions.
ANSWER: phosphates [or PO43-]
[10h] Early research of CDK function originated with Paul Nurse and Melanie Lee’s study of cdc2 in this organism. A tiny cell phenotype results from mutating wee1 in this organism.
ANSWER: S. pombe [or Schizosaccharomyces pombe; or fission yeast; prompt on yeast; reject “Saccharomyces cerevisiae” or “baker’s yeast” or “brewer’s yeast”]
