More about DNA. Let X be the amount of DNA present in the gamete of an organism that has a diploid chromosome number of 4. Assuming all chromosomes to be of approximately the same size, how much DNA (X, 2X, 1/2X, and so on) would you expect in each of the following?

  1. (a) A zygote immediately after fertilization
  2. (b) A single sister chromatid
  3. (c) A daughter cell following mitosis
  4. (d) A single chromosome following mitosis
  5. (e) A nucleus in mitotic prophase
  6. (f) The cell during metaphase II of meiosis

After the process of duplication, each chromosome consists of two sister chromatids. B. Human body cells have two copies of each type of chromosome. C. In any human body cell, all chromosomes have the same shape and length.
Give only typing answer with explanation and conclusion  Your analysis has identified that this new organism has same chromosomal structure as that of eukaryotes on earth. However, the average length of linker DNA of the new organism is 100 bp. If the haploid genome of the new organism has a size 6 billion bp, how many nucleosomes will be in this new organism?
