Question
Please fill in the table below, indicating how many chromosomes and DNA molecules there are in one cell at the end of each of the different stages of mitosis or meiosis for an organism that has a diploid chromosome number 2N = 16. 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, at the end of the specified stage of mitosis/meiosis.

A chromosome is a DNA molecule with part or all of the genetic material (genome) of an organism. Most eukaryotic chromosomes include packaging proteins which, aided by chaperone proteins, bind to and condense the DNA molecule to prevent it from becoming an unmanageable tangle. So, a chromosome is made up of a single DNA molecule,in the S-phase DNA replicates and two sister chromatids are formed. In G2 phase checking occurs, any needed repairs also occurs and then prophase starts. So, DNA molecule have already been duplicated when the cell is in G2 phase. Mitosis occurs independently of meiosis.
