Homework Answers
B is the correct answer
A protein, an inhibitor of sister chromatid separation (ISS) binds to the chromatids and keeps the sister chromatids from separating and entering anaphase until right moment. In anaphase, separation of sister chromatids and their movements to opposite poles.

Q.For a cell with 3 pairs of chromosomes make a diagram of the events during mitosis. There should be 5 parts to your diagram: prophase, prometaphase, metaphase, anaphase and telophase. Remember to label the important parts in each phase.

A somatic cell from a diploid species with 2n=4 (4 chromosomes or two sets of homologous chromosomes) is undergoing mitosis. Draw the cell and chromosomes during G1, during G2, during metaphase, and the two cells that result from mitosis at the end. Label each stage in your drawing, and also label sister chromatids and homologous chromosomes as appropriate.

Draw a diagram showing the movement of chromosomes within the cell during mitosis for a 2n = 4 organism (i.e., a diploid organism with two chromosomes like the one pictured on the right). Your diagram should include: 1.1) Labels of each phase of the cell cycle. 1.2) Labels indicating where A) DNA replication occurs, B) checkpoints occur, and C) mutations occur. 1.3) For each phase, label the location of the alleles. 1.4) An expanded section for mitosis with the following...
