Question

Mitosis, meiosis and SNA isolation Assume a cell has 20 homologous pairs of chromosomes and 20 picograms (pg) of DNA at Ga. At G1, the cell would contain ______ pg of DNA. If this cell were to divide by mitosis, each daughter cell would contain ______chromosomes and _______ pg of DNA. If this cell were to divide by meiosis it would produce _____ daughter cells, each containing _______ chromosomes and pg of DNA. You are studying for the lab exam and have made note cards with drawings of each phase of mitosis and meiosis. Unfortunately, you dropped the cards and now they are mixed together. To the right of each picture, list all possible phases for each cell including 2n number.

Explanation / Answer

1. At G1 it will have 10 picograms of DNA. 2. 20 chromosomes and 20 picograms of DNA 3. 20 chromosomes and 10 picograms of DNA
