@xxjmodxx Very doubtful. Receptors are VERY specific. RNA splicing is the only answer.
could you have put that s phase doubles chromosomes number in both mitosis and meiosis and ensures that each cell gets the appropriate number?
@apandia Possibly. Depends if they r looking for events only in meiosis/mitosis
also I put that dna is repetitive but unambiguous, so one gene or code could express thousands of smells
@CGlynn I’m no expert but “Rather than binding specific ligands, olfactory receptors display affinity for a range of odor molecules, and conversely a single odorant molecule may bind to a number of olfactory receptors with varying affinities”
So based on this would my answer receive credit…
I think you guys read in to it too much… it was essentially an analyzing question- not related to RNA or genes
for 1 e) what are the 2 features?
@xxjmodxx The question said there were 1000 genes, not 1000 receptors. They were looking for RNA splicing, but I suppose your answer may work.
@TopOne See my answers on page 56 of this forum.
@xxjmodxx Every single kid in my school said RNA splicing
Took AP bio last year looks at frqs for this year : WTF is this stuff .
can multiple phylogenetic trees be created from that info or is there just one correct sequence?
ok for 8 c) can you say nonspecific immunity?
@CGlynn you’re probably right but it said each of the 1000 genes corresponds to 1 receptor “Mammalian genomes typically have approximately 1,000 functional odorant-receptor genes, each encoding a
unique odorant receptor”
Yours is probably conventionally correct so im praying im right. Good chance I’m not.
Right but unique doesn’t mean they only encode one each. It just means there are no repeats
i could have done SO much better had I read the “each” part
@CGlynn so am I dead wrong? You can be honest. I only talked about what I mentioned.
shit i screwed this stuff up completely.
@xxjmodxx I don’t think you’re dead wrong, I’d say there’s a good chance you get it. It’s just I was always taught that a receptor was very specific.
@CGlynn what did u get for some other stuff? Im really hoping I did well on FRQ cuz multiple choice didnt bode incredibly well for me. I got everything right on the first two but the last ones I goofed a bit in certain spots. For example on the snakes I was too stupid to realize it said “Juvenile” so instead I wrote that the snakes may have not shown favorable mating behavior. I mean if they are too young of course they won’t be doing sexy dances for the women but It may be a stretch. What do you think about that… and others?
