Homework Answers
1) The chromosomes would still condense but they would have no spindle to attach
Since colchicine blocks spindle fibre formation there will not be any mitotic spindle fibres to attach to the chromosomes.
2) DNA replication occurs simultaneously with segregation of DNA to opposite ends of the cell.
In mitosis DNA replication occurs is S phase of the cell cycle before the cell division phase which is M or mitotic phase

Unit 3 Study Resource Meiosis • Process by which diploid cells create haploid cells NOT part of the cell cycle > only some cells ever undergo meiosis During meiosis I, homologous chromosomes line up to allow them to be separated into two new cells o They can become "tangled" during this phase, which leads to crossing-over (rearranging the alleles) O Result of meiosis I is two non-identical haploid cells Meiosis Il looks very similar to mitosis, in that sister chromatids...
