Chapter 8, Problem 7WIO
Summary Introduction
To determine:
The effect on the shape of rubber band if it is twisted many times and its similarity and differences with the cell division.
Introduction:
Binary fission is the process by which a cell divides mitotically or meiotically. The first step of cell division is the duplication of the entire genome. The genome consists of one or more chromosome. Chromosomes are known as the individual molecules of DNA with their associated proteins

Students have asked these similar questions
Some plants have a hard, cellulose layer protecting them. This hardened layer will prevent the detergent from breaking down the cell wall. Can you think of another way to break open the cells?
Note: The cell lysis and mashing the fruit with your hands or using a blender helps homogenize the DNA. Homogenization is the process of releasing DNA from the nuclei of the cells by breaking apart the cell walls, plasma membranes and nuclear envelope. It also helps to create a uniform mixture.
Although you can see chromosomes as they are lined up or being separated
during mitosis with a light microscope, you cannot see the DNA while it is being
replicated with the same microscope. Why not?
Chromosomes do not contain protein until mitosis.
Chromosomes are outside the nucleus during replication.
Chromosomes are visible only before DNA has been duplicated.
Chromosomes are not condensed during S phase so they cannot be seen by light
microscopy.
A cell containing a single chromosome is placed in a medium containing radioactive phosphate, making a new DNA strand formed by DNA replication radioactive. The cell replicates its DNA and divides. Then the daughter cells replicate their DNA and divide, resulting in a total of four cells. Sketch the DNA molecules in all four cells, showing a normal DNA strand as a solid line and a radioactive DNA strand as a dashed line.

- Which type of chromatin makes dark bands? Does this type usually contain more or less active genes? Group of answer choices 1. Euchromatin; less active genes because the DNA is more tightly packed 2. Heterochromatin; more active genes because DNA is less tightly packed 3. Heterochromatin; less active genes because the DNA is more tightly packed 4. Euchromatin; more active genes because DNA is less tightly packedarrow_forwardHow does DNA replication occur in a precise manner to ensure that identical genetic information is put into the new chromatid? See Figures 8.12 and 8.13. FIGURE 8.12 In DNA replication, the two polynucleotide strands uncoil, and each is a template for synthesizing a new strand. A replicated DNA molecule contains one new strand and one old strand. This mechanism is called semiconservative replication. FIGURE 8.13 A close-up look at the process of DNA replication. (a) As the strands uncoil, bases are added to the newly synthesized strand by complementary base pairing with bases in the template strand. The new bases are linked together by DNA polymerase. (b) DNA synthesis can proceed only in the 5 3 direction; newly synthesized DNA on one template strand is made in short segments and linked together by the enzyme DNA ligase.arrow_forwardOpen the bag of fruit and add 2 teaspoons of your DNA extraction buffer.

- Put the following levels of chromosome organization in order from least complex (least packaged form) to most complex (most packaged form). DNA strand 30-nm fiber Heterochromatin Euchromatinarrow_forwardDNA replication is a process that involves copying the DNA molecule. If a single base was miscopied, what would be a possible result of this for the cell in which it happened? Top of Form All the proteins the cell creates from the miscopied strand will do different jobs than the old ones. If the new sequence codes for the same amino acid as the original cell, it will function normally. Both new DNA strands will end up together in a new cell, and the inaccurate one will be discarded. Any miscopied DNA will be replaced with an accurate DNA copy once the cell divides.arrow_forwardHow many chromosomes are shown in the picture below? How many chromatids?arrow_forward
- What are the substances that constitute the chromatin? What is the difference between chromatin and chromosome?arrow_forward1 3 4 Here is a replication fork during S phase of the cell cycle. DNA strands are labeled 1-4. After mitosis and cytokinesis is complete, One daughter cell will have strands 18&2, another will have strands 3&4 One cell will have 1&3, the other will have 2&4 Each of the strands (1-4) will be in a different cell. All four strands will end up in the same cell, and the other cell will have the complementary strands. Both A and B are equally likely.arrow_forwardAcetocarmine is a natural stain that comes from an insect. This stain binds to chromatin and stains it red. DNA in eukaryotic cells is packed with proteins to form a structure called chromatin; thus it is useful for identifying nuclei. Draw a cell from a potato and label what would be stained with acetocarmine.arrow_forward
