1. What form of inheritance does this pedigree show?
2. What is wobble?
3. What kind of operon is the trp operon?
Yes, all correct (LittleMissNyan, you also got it correct. Number 3 is Division C, but I'm not sure about number 2...)amk578 wrote: ↑December 29th, 2019, 2:26 pm1. autosomal dominantreninkidney wrote: ↑December 29th, 2019, 2:03 pm

2. Wobble is where non-Watson-Crick base pairing occurs in the 3rd codon position, this allows tRNA anticodons to pair with more than one codon.
3. trp operon is a negative repressible operon.
Quick question: Are these questions for division C or am I just very unprepared for the type of questions in regionals?amk578 wrote: ↑December 31st, 2019, 8:33 pm 1. In eukaryotic ribosomes, the size of the small subunit is _____ and the large subunit is ______. Combined, a eukaryotic ribosome is ______. (give answer in S units)
2. Describe the difference between an exonuclease and endonuclease.
3. Is DNA replication faster in eukaryotes or prokaryotes?

I feel like these could be considered harder Div Bs and medium Div C?? Honestly, I’m kinda confused on this too, but my main strategy is just learning my way through the topics listed and then hitting up the question forums and deepening my knowledge.

2. Exonucleases remove nucelotides one by one off the ends and have no delay; endonucelases make internal cuts producing segments of DNA with a delay.
3. DNA replication is faster in prokaryotes than eukaryotes
Probably mid-level Div C would be about correct, yes.
