2) The amount of DNA per cell of a particular species is measured in cells found at various stages of meiosis and the following amounts are obtained:
3.7 pg, 7.3 pg, 14.6 pg
Match the amounts of DNA above with the corresponding stages of the cell cycle. You may use more than one stage for each amount of DNA.
A. G1
B. Prophase I
C. G2
D. Following telophase II and cytokinesis
E. Anaphase I
F. Metaphase II
Homework Answers
G1---7.3pg
Prophase 1---7.3pg
G2----7.3pg
Following telophase 11 and cytokinesis---3.7pg
Anaphase 1--7.3pg
Metaphase 11---- 3.7pg

Simulate meiosis by drawing One pair of chromosomes and no crossing over Instructions: Set up your cell. The cell you start with should be: A diploid cell It should contain 1 pair of homologous chromosomes It should be in G1 of the cell cycle, before DNA replication occurs Be sure to show 2 genes that are both heterozygous . Go through the steps of meiosis. Be sure to show and label these in your pictures: Label homologous chromosomes and sister...
