Figure 6.4 Which of the following is the correct order of events in mitosis? a. Sister chromatids line up at the metaphase plate. The kinetochore becomes attached to the initotic spindle. The nucleus re-forms and the cell divides. The sister chromatids separate. b. The kinetochore becomes attached to the mitotic spindle. The sister chromatids separate. Sister chromatids line up at the metaphase plate. The nucleus re-forms and the cell divides. c. The kinetochore becomes attached to metaphase plate. Sister chromatids line up at the metaphase plate. The kinetochore breaks down and the sister chromatids separate. The nucleus re-forms and the cell divides. d. The kinetochore becomes attached to the mitotic spindle. Sister chromatids line up at the metaphase plate. The kinetochore breaks apart and the sister chromatids separate. The nucleus re-forms and the cell divides.

In Coleus , the somatic cells are diploid with 24 chromosomes. How many of each of the following is present in each cell at the stage of mitosis and meiosis indicated below? kinetochore at prophase chromosomes at anaphase chromatids at metaphase 1 chromosomes at telophase after cytokinesis centromeres at anaphase chromosomes at telophase II after cytokinesis centromere at anaphase I chromatids at metaphase

The result is 10) daughter cells event that causes genetic diversity takes place in called (n? 2n?). An organism with two of each kind of chromosome is said to be: (3) tetraploid (1) haploid (2) diploid (4) polyploid. In multicellular organisms, mitosis results in: (1) reproduction (2) growth and repair (3) sperm and egg production (4) fertilization. If an organism produced an egg that had 20 chromosomes, the body cells of that organism should have: (1) 10 chromosomes (2) 20 chromosomes (3) 30 chromosomes (4) 40 chromosomes. 11) is what helps us grow and is why we are all unique!

A somatic cell has the genotype DdEe. All chromosomes in this organism are metacentric. Show metaphase and the results of mitosis if the D and E locus are linked on the same chromosome in trans configuration. A sexually reproducing organism has the following phenotype DdEeAaTt: The D and E loci are on the same arm of a metacentric chromosome in cis configuration. The A locus is on the long arm of an acrocentric chromosome and the T locus is on a telocentric chromosome. 2.1. What is the haploid number of this organism? 2.2. Using diagrams show a ceii at metaphase of mitosis and show the results of mitosis.

The following diagram is meant to help you understand how the amount of DNA in a cell changes as the cell cycle progresses. On the diagram, identify two of the stages of the cell cycle being described and identify how much DNA exists per cell, where a cell is defined as a distinct nucleus. Note that the sequence of images highlights one of the chromosomes of the cell. The other chromosomes, while also present, are faded in the background.
