You have discovered a strain of mutant yeast cells that divides normally at 30°C but cannot enter M phase at 37°C. You determine that its mitotic cyclin and mitotic Cdk can form a normal M-Cdk complex at both temperatures. Which of the following temperature-sensitive mutations could NOT be responsible for the behavior at 37°C ? a. inactivation of an enzyme that ubiquitinates M cyclin b. inactivation of a protein kinase that acts on the mitotic Cdk kinase c. a decrease in the levels of a transcriptional regulator required for producing M cyclin d. inactivation of a phosphatase that acts on the mitotic Cdk kinase g

This is s cute awee : (( . well if she's showing you signs that she may like you , then shoot your shot ! don't be afraid . & if you're unsure that she's giving you these signs , then wait out for a little bit . most girls are different . some may act really sweet , but only bc you're a good friend of hers . that , or she might like you . you just never know . but i think you should sit down with her & tell her how you feel . but don't be awkward & shy . just be straight up & tell her how you feel . if the feelings aren't mutual , then don't cry about it . you need to respect her decision & look for others in the world . feelings can be difficult & confusing , but don't be afraid to show them . i say you play it out & if you're still unsure about it , talk to her . - rach

A) the sequence of bases would halt the production of any proteins.
