Document Summary

Human somatic (body) cells contain between 7 and 14 picograms of. Human somatic cells contain between 7 and 14 picograms of dna. The haploid number of chromosomes for a hedgehog is 44. Yes (important that each daughter cell gets one set of each type of chromosomes) No (doesn"t matter which one goes to either cell) Same #, same amount (both replicated chromosomes) The diploid number of chromosomes for a horse is 64. Prior to crossing-over, the sister chromatids in replicated chromosomes are: genetically identical, not genetically identical. After crossing-over the sister chromatids are identical: true, false. A cell in g1 of the cell cycle contains a total of 6 chromosomes in 3 homologous pairs. It undergoes meiosis, during metaphase ii each cell would contain: 3 chromosomes with no pairs, 3 chromosomes with 3 pairs (never pick both odd #s, should be, 6 chromosomes with no pairs, 6 chromosomes with 3 pairs.

Suppose that a cell in G1 contains 10 picograms (pg) of DNA. How many picograms would you expect to find in this same cell during G2?

Note that a picogram (pg) is a measured quantity/mass. Think about how the amount of DNA changes as the cell progresses from G1 to G2.

Suppose that a single somatic cell undergoes mitosis and cytokinesis. If you compared the original parent cell in G1 with the daughter cells that are produced, which of the following statements would be true?

_____________________

The daughter cells have the same number of chromosomes and half the amount of DNA.

The daughter cells have half the amount of cytoplasm and half the amount of DNA.

The daughter cells have half the number of chromosomes and half the amount of DNA.

The daughter cells have the same number of chromosomes and the same amount of DNA.

The daughter cells have the same number of chromosomes and twice the amount of DNA.

A cell in G1 of interphase has 12 chromosomes. How many chromosomes and DNA molecules will be found per cell when this original cell progresses to the following stages?
....G2 of interphase, Metaphase I of meiosis, Prophase of mitosis, Anaphase I of meiosis, Anaphase II of meiosis, Prophase II of meiosis, After cytokinesis following mitosis, and After cytokinesis following meiosis II.

**If you wouldn't mind, please arrange them in chronological order that it happens in the process so it's easier to understand, thanks**

Each chromosome consists of only one centromere, but during certain times in the cell cycle could consist of two DNA molecules (sister chromatids). If a cell in G1 of interphase has 14 chromosomes, answer the following questions:

1. In G2 of interphase how many chromosomes will be found per cell?

2. In G2 of interphase how many DNA molecules will be found per cell?

3. After teleophase I of meiosis how many chromosomes will be found per cell?

4. After teleophase I of meiosis how many DNA molecules will be found per cell?

5. After cytokinesis of mitosis how many chromosomes will be found per cell?

6. After cytokinesis of meiosis II how many DNA molecules will be found per cell?
