Question

1. Please fill in the table below, indicating how many chromosomes and DNA molecules there are in one cell during the different stages of mitosis or meiosis for an organism that has a diploid chromosome number 2N = 22. Remember that for some phases there will only be one cell, and for some, there will be two cells. Give me the number of chromosomes and DNA molecules that are present in one cell, regardless of how many cells are present at that time.

# chromosomes # dna molecules G2 Prophase Mitosis Metaphase Mitosis Anaphase Mitosis Telophase Mitosis Prophase 1 Meiosis Prometaphase 1 Meiosis Metaphase 1 Meiosis Telophase 1 Meiosis Prophase 2 Meiosis Metaphase 2 Meiosis Anaphase 2 Meiosis Telophase 2 Meiosis

Explanation / Answer

Taking 4 as N,

G2 - 4 chromosomes

Prophase: 4 chromosomes and 8 chromatids

Metaphase: 4 chromosomes and 8 chromatids

Anaphase: 0 chromosomes and 8 chromatids

Telophase: 2 cells with 4 chromosome each, 0 chromatids

-------------

Meiosis 1:

Prophase: 4 chromosomes, 8 chromatids

Metaphase: 4 chromosomes, 8 chromatids

Anaphase: 0 chromosomes, 8 chromatids

Telophase: 2 cells with 2 chromosomes each, 0 chromatids

------------

Meiosis 2:

Prophase: 2 chromosomes and 4 chromatids

Metaphase: 2 chromosomes and 4 chromatids

Anaphase: 0 chromosomes and 4 chromatids

Telophase: 4 cells with one chromosome each, 0 chromatids
