Nonsister chromatids:
a. are attached at the centromere
b. both come from the father
c. are segregated randomly at meiosis I
d. come from both the maternal and paternal genomes
e. none of the above
(I know crossing over for nonsister chromatids occur duringmeiosis I...)
Telomeres are specialized repetative DNA sequences found at theends of chromosomes. How many telomeres are present in ahuman cell at prophase I of meiosis?
a. 23
b. 46
c. 92
d. 184
e. 368
A human cell has 23 chromosomes with 46 chromosome. In whichphase of meiosis is it?
a. telophase II
b. metaphase I
c. prophase II
d. prophase I
e. all but c
A triploid cell contains 3 sets of chromosomes. If acell of a usually diploid species with 42 chromosomes per cell istriploid, this cell would be expected to have which of thefollowing?
a. 63 chromosomes on 31 1/2 pairs
b. 63 chromosomes in 21 sets of 3
c. 63 chromosomes, each with three chromatids
d. 21 chromosome pairs and 21 unique chromosomes
(I'm leaning toward b, but I'm not sure)
