Chromosomes are composed of two strands during certain stages of cell division.
Homework Answers
Chromosome is made up two strands known as sister chromatids which are joined to each other at the centromere. These sister chromatids are exact copies of each other, that results after DNA replication during S phase of the cell cycle. Each chromosome is made up of two chromatids during metaphase of the cell cycle, in which they are aligned in the equator of the cell after which they separate and move to opposite poles of the cell.

Meiosis is composed of two chromosomal division called Meiosis I and Meiosis II. Each of the two divisions consists of Prophase, Prometaphase, Metaphase, Anaphase and Telophase and each of these phases is designated I or II according to which division it is a part of. Be sure you know what happens in each phase in regard to the chromosomes, chromatids, spindles and the nuclear envelope. During which phase does synapsis occur and crossing over begin? And in which division, Meiosis I or Meiosis II...

Draw the stages of meiosis for an animal cell where 2n (diploid number of chromosomes) =4 chromosomes. Label the cleavage furrow, cell plate, spindle fibers, & centrioles (if present for that stage). Diagram the stages of meiosis for a plant cell where the diploid number is 6 chromosomes. Label the cleavage furrow, cell plate, spindle fiber, & centrioles (if present for that stage).

Assume that n = 2 in a cell. Draw schematic diagrams to follow the chromosomes of this cell as the cell goes through the various phases of the cell cycle. Be sure to include the stages of mitosis and cytokinesis. Use large and small chromosomes to differentiate between the two chromosomes, and use red for the maternal chromosomes and blue for the paternal chromosomes.
