Chapter 12: The Cell Cycle (Mitosis)
2024/2025 Exam Questions and Correct
Answers | New Update
What are the three key roles of cell division? State each role and give an
example - 🧠ANSWER ✔✔Reproduction: an amoeba single celled
eukaryote divides into two cells. Growth+Development: fertilized egg
divides into two cells, beginning embryo formation. Tissue Renewal:
dividing bone marrow will give rise to new blood cells
What is meant by the cell cycle? - 🧠ANSWER ✔✔the life of a cell from the
time it's first formed from a dividing parent cell until its own division into two
cells
What is a Genome? - 🧠ANSWER ✔✔the cell's entire collection of DNA
eukaryotic genome (+human genome) - 🧠ANSWER ✔✔many DNA
molecules (human cell = 2m DNA)
prokaryotic genome: - 🧠ANSWER ✔✔a single long DNA molecule
how many chromosomes are in a human somatic cell? - 🧠ANSWER ✔✔46

, How many single-strand chromosomes are in a cell after S phase -
🧠ANSWER ✔✔92
chromatid: - 🧠ANSWER ✔✔half of duplicated chromosome, genetically
identical
what is mitosis/ cytokinesis? - 🧠ANSWER ✔✔division of the nucleus/ of the
cytoplasm
What occurs in meiosis & how is the chromosome # of daughter cells
different? - 🧠ANSWER ✔✔variation of cell division which yields
nonidentical haploid daughter cells for cell division. Daughter cells have
half the amount of chromosomes of the parent cell, but a mixture of traits
from both parents.
What are the components of the mitotic spindle and what is the source of
these components? - 🧠ANSWER ✔✔consists of microtubule fibers and
associated proteins. source: the microtubules of the cytoskeleton partially
disassemble.
How does the mitotic spindle form & break apart? - 🧠ANSWER ✔✔spindles
from centrosomes elongate by polymerization: incorporating subunits of the
protein tubulin & depolymerize by losing them
