Event that occur in prophase
Did you know?
WebThe key event in prometaphase I is the attachment of the spindle fiber microtubules to the kinetochore proteins at the centromeres. Kinetochore proteins are multiprotein complexes that bind the centromeres of a chromosome to the microtubules of the mitotic spindle. Microtubules grow from centrosomes placed at opposite poles of the cell. WebBy this reasoning, the fraction of recombination events occurring during meiotic prophase would equal twice the number of prototrophs containing both a recombinant and a nonrecombinant chromosome divided by the total number of prototrophs with two PCR products.
