what statement below is TRUE of the spindle during mitosis a

what statement below is TRUE of the spindle during mitosis and meiosis? a. the spindle always separates sister chromatids during anaphase b. the spindle always separates homologous chromosomes during anaphase c. chromosomes are always attached to both spindle poles during metaphase d. the spindle always attaches to chromosomes at the kinetochore

which of the following represents things that are identical? a. two alleles for the same gene in a homologous chromosome pair b. the sequences of dan in the two sister chromatids of a chromosome after meiosis I c. the number of homologous chromosomes per cell before and after meiosis I d. the number of chromosomes in each of the four daughter cells after meiosis II

what problem would most likely occur if a haploid cell attempted to perform meiosis? a. the cell could not replicate its DNA prior to meiosis b. the cell could not pair homologous chromosomes during meiosis I c. the cell would produce diploid daughter cells

Solution

1Q). a. the spindle always separates sister chromatids during anaphase ----> FALSE (sister chromatids are not separated during \"anaphase I,\" it is not \"always\" )

b. the spindle always separates homologous chromosomes during anaphase ----> FALSE (it does not occur in \"anaphase 2,\" so, it is not \"always\")

c. chromosomes are always attached to both spindle poles during metaphase ----> FALSE (chromosomes align at the midline during metaphase)

d. the spindle always attaches to chromosomes at the kinetochore ---> TRUE
