Although you can see chromosomes as they are lined up or being separatedduring mitosis with a light microscope, you cannot see the DNA while it is beingreplicated 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 lightmicroscopy.

The chromosomes are lined up in mitosis before they are separated. However, the Chromosomes are…

Oogenesis

The formation of the ovum (mature female gamete) from undifferentiated germ cells is called oogenesis. This process takes place in the ovaries (female gonads). Oogenesis consists of three stages known as the multiplication phase, growth phase, and maturation phase.

Cell Division

Cell division involves the formation of new daughter cells from the parent cells. It is a part of the cell cycle that takes place in both prokaryotic and eukaryotic organisms. Cell division is required for three main reasons:

Question

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.

1 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.
Mitosis (Name the cell division phase on the line.) DNA and centrosomes are replicated. Name: Chromatin condenses and supercoils to form dense chromosomes. Since DNA was previously replicated, the chromosomes are now present as paired sister chromatids. Centrosomes move to opposite sides of the nucleus and will define the orientation of the division. Name: DO
You would expect to find chromatin in which form during the Gap2 phase of the cell cycle? Replicated heterochromatin Chromatin in the same form as during metaphase of meiosis. Chromatin in the same form as during metaphase of mitosis Un replicated heterochromatin Replicated euchromatin
Which of the following statements is TRUE? O Interphase chromosomes are loosely compacted, overlapping, and intertwined with each other within the nucleus. O Interphase chromosomes are loosely compacted and do not associate with histones until the cell is preparing to divide. O Interphase chromosomes are also known as euchromatin. Condensed, metaphase chromosomes are also known as heterochromatin. O Radial loops in the condensing chromosome are formed due to interactions between 30 nm fibers and the scaffolding proteins of the nuclear matrix - producing the 300 nm fiber of the chromosome O None of these are TRUE
During anaphase of mitosis, sister chromatids are pulled to opposite poles of the cell by spindle fibers. When are sister chromatids officially considered to be daughter chromosomes in this phase? When they're no longer attached at the centromere. When two cells are formed from the division of cytoplasm and mitosis is complete. When replication is complete. O When the spindle fibers detach.
Match the description on the left with the correct term on the right When the nuclear membrane dissolves andy the chromosomes appear Options: When the nuclear membranes reform and visible chromosomes go back to less coiled Prophase chromatin Metaphase Chromosomes line up along the midline of the Telophase cell Anaphase When sister chromatids separate and move to opposite sides of the cell
Which of the following does not occur during mitosis? condensation of the chromosomes separation of sister chromatids replication of the DNA O spindle formation
The duplicated chromosomes are separated during: O Nucleosis O Cytokinesis II O Mitosis O Cytokinesis
In which state, the sex chromosomes are present in a cell? Euchromatin O Heterochromatin Centromere O Telomere
Figure 10.6 Which of the following is the correct order of events in mitosis? Sister chromatids line up at the metaphase plate. The kinetochore becomes attached to the mitotic spindle. The nucleus reforms and the cell divides. Cohesin proteins break down and the sister chromatids separate. The kinetochore becomes attached to the mitotic spindle. Cohesin proteins break down and the sister chromatids separate. Sister chromatids line up at the metaphase plate. The nucleus reforms and the cell divides. The kinetochore becomes attached to the cohesin proteins. Sister chromatids line up at the metaphase plate. The kinetochore breaks down and the sister chromatids separate. The nucleus reforms and the cell divides. The kinetochore becomes attached to the mitotic spindle. Sister chromatids line up at the metaphase plate. Cohesin proteins break down and the sister chromatids separate. The nucleus reforms and the cell divides.
Define the following terms: a. chromosome b. chromatin
How 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.
