what are the main reasons for for mapping?
|
1. UNDERST G FUNCT
2. underst g revol 3. help w strain build |
|
|
positional cloning
|
using map position to physically isolate the g
|
|
|
_____________ is called when a g locat affects its funct
|
neighborhood effect
|
|
|
g of ______________ in e coli are often next to each oth
|
related function
|
|
|
In genome evol you look at ?
|
the relative positions of the same g in diff organism
|
|
|
to build a strain it helps to know if?
|
the alleles you want are linked or not
|
|
|
in euk, recombin analysis can not be used to map the loci of?
|
centromeres.
|
|
|
in neurospora
first division segregation is? |
when the 2 diff alleles segregate into 2 daughter nuclei at first div of meiosis
|
|
|
neurospora
second div segregation patterns? |
as a res of crossover in centrom to locus region. the A and a alleles are still tog in nuclei at end of 1rst div of meiosis
|
|
|
what are M1 patterns?
|
first division segregation pattern.
|
|
|
neurospora
freq of MII patterns should be proportional to? |
the size of the centromere a/A region. an can be used as meas of that region
|
|
|
neurospora
what do you do to convert the MII freq to map units? |
divide the MII (in the example it was 14 percent) by 2.
|
|
|
neurospora
is MII freq the same as map units? |
no
|
|
|
a crossover in any meiosis event results in only _______________ recombinant chromatids
|
50 percent
|
|
|
problem 1
why can you assume that the unaffected people marrying into the family dont have Nail-patella syndrome? |
bec the problem states that the disease is rare. its unlikely they are carriers.
|
|
|
nail patella syndrome
whats an indicator that its dominant? |
that it shows up in all 3 generations
