The mutants have constitutive expression of the nop operon, which includes the genes nop1 and nop2. One of the mutants is a point mutation in a DNA-binding site, and the other is a deletion of the gene which encodes the DNA-binding protein.Which term describes the regulatory function of the DNA-binding protein?The scientist then performs a experiment mating the two haploid yeast together to determine which mutation is in the DNA-binding protein and which is in the dna-binding site. The experimental setup is listed below, wherein a minus indicates a lose-of-function mutation, and a plus indicates the wild type allele.How will nop1 and nop2 be expressed if huh1 encodes the dna-binding protein and huh2 is a mutation in the binding site? How will nop1 and nop2 be expressed if huh2 encodes the DNA-binding protein and huh1 is a mutation in the binding site?

Wait, a dragon? Those fantasy books had really taken a toll on my sense of reality. My senses came to me as I discovered that, of course, no dragon had found its way into my classroom. Unfortunately, there was a fiery, heavy exhale that reached my desk. I looked up, nervously, as Mr. Anderson stared down at me with his arms crossed, his brow furrowed with disapproval. I had fallen asleep. "Off in the ozone again?" my teacher asked as I sat there embarrassed. "Sorry, Mr. Anderson. Late night, you know?" There was no reason to explain the exhausting quest I had endeavored to complete, well into the deep forest and across the unfathomable heights of the great mountains. I knew my fantasies didn't belong in school. Very few of my classmates would continue talking to me after I ranted about the vast territories my heroes traveled, or the colossal dangers that await victims in the forbidden swamps. My teacher, however, was fully aware of my interests because, as he noted, I talk in my sleep. The next day, Mr. Anderson wrote an assignment on the board right off the bat. Halfheartedly, I glanced at the writing at the front of the room. "Write your own story with fantastical creatures and include elaborate detail." My enthusiasm was felt throughout the room as I shifted my posture quickly and began shuffling papers erratically. My dreams had become a reality as I envisioned a new quest, a new mission to embark on that would transform the fantasy genre forever! A week later, I sprang up to the front of the classroom to read my story, delivering powerful dialogue and suspenseful plot twists. Everyone shifted in their seats, wriggling around with the introduction of a new setting, waiting in anticipation as each character turned a new corner. My teacher was in awe, but proud and happy that I was able to get out of my rut and finally take interest in school. After the 14 full pages came to a close, and after the bell had already rung, my classmatesthose who never spoke a word to mecheered with great enthusiasm as I walked back to my desk in a full, confident stride.
