Chapter 9, Problem 10TYU
FOCUS ON INFORMATION
The continuity of life is based on heritable information in the form of DNA. In a short essay (100‒150 words), explain how the process of miles is faithfully parcels out exact copies of this heritable information in the production of genetically identical daughter cells.

In the tracking chromosomal DNA movement through mitosis experiment, how many chromosomes did each of your daughter cells contain? Why is it important for each daughter cell to contain information identical to the parent cell? How often do human skin cells divide? Why might that be? Compare this rate to how frequently human neurons divide. What do you notice?
Please explain
In which stage(s) of the cell cycle, mitosis or meiosis
do each of these processes occur (multiple stages apply to some)
Crossing-over:
Chromosome supercoiling:
Separation of sister chromatids:
DNA synthesis:
Chromosome reduction from 2N to N:
4. A previously undiscovered single celled organism was found living at a great depth on the ocean floor. Its nucleus contains only a single, linear chromosome consisting of 7x10^6 nucleotide pairs of DNA coalesced with three types of histone-like proteins. The analysis of individual nucleosomes revealed that each unit contained one copy of each protein and that the short linker DNA had no protein bound to it If the entire chromosome consists of nucleosomes (discounting any linker DNA), how many are there and how many total proteins are needed to form them?

- Rainbow trout go through a unique genetic reproductive process. Female eggs are diploid, while male sperm are haploid. In the wild, when the sperm fertilizes an egg, the extra set of chromosomes is eliminated, resulting in a diploid offspring.The process that produces the sperm and egg, and the process the offspring use to grow into adults are, respectively, Select one: a. Process to produce sperm and egg Process used for growth of the offspring Mitosis Cytokinesis b. Process to produce sperm and egg Process used for growth of the offspring Mitosis Meiosis c. Process to produce sperm and egg Process used for growth of the offspring Meiosis Cytokinesis d. Process to produce sperm and egg Process used for growth of the offspring Meiosis Mitosisarrow_forwardWhy do eukaryotic cells need to go through the elaborate procedure of mitosis rather than simply dividing during interphase? Select as many answers as apply. 1.Daughter cells must be genetically identical to the mother cell, for homeostasis and ordered tissue growth. 2.Bivalent chromosomes must condense and be separated in an orderly fashion, to allow equal distribution of copies into daughter cells 3.Physically dividing the nucleus during interphase would likely lead to gross chromosome breakage and highly unequal assortment of genetic information into daughter cells. 4.Dividing the nucleus during interphase would have the same outcome as mitosis 5.Daughter cells must have half the number of chromosomes after mitosis than the mother cells 6.The homologous pairs of chromosomes need to be separated, to ensure copies go to the daughter cells.arrow_forwardIn class, we talked about flow cytometry which allows scientists to determine what stage of the cell cycle cells are in by measuring their DNA content.
