UW Madison Bio 101 Exam 2 Questions and
Answers 100% Pass
Meiosis lead to the production of ________. - ANS Gametes
Mitosis leads to the production of ________. - ANS Somatic cells
What are the functions of mitosis? - ANS Growth, repair/replacement, and asexual
reproduction in planaria.
What is the G1 stage responsible for? - ANS Cell growth, transcription/translation,
duplication of organelles, and to prepare for DNA replication.
What is the S phase of interphase responsible for? - ANS DNA replication. It only occurs
during this phase.
What is the G2 phase of interphase responsible for? - ANS Transcription/translation, prepare
to divide. Centrosomes appear.
What are sister chromatids? - ANS Replicated chromosomes. Attach to each other at the
centromere.
What is a kinetochore? - ANS A protein structure where microtubules attach during mitosis.

T/F: Prokaryotic cell division is clonal. - ANS True. Cell division occurs by binary fission.
What occurs during prophase (mitosis)? - ANS Chromosomes condense (metaphase
chromosomes), the nuclear envelope degrades, centrosomes migrate to opposite poles of the
cell and the mitotic spindle forms.
What occurs during metaphase (mitosis)? - ANS The chromosomes line up on the metaphase
plate.
What occurs during anaphase (mitosis)? - ANS The separation of DNA. Cohesions decay and
kinetochore microtubules shorten (sister chromatids separate). Non-kinetochore microtubules
get longer (cell elongates).
What occurs during telophase/cytokinesis (mitosis)? - ANS The nuclear envelope reforms,
chromosomes decidedness, a cleavage furrow forms (microfilament ring). End with 2n = 4
Where in the cell cycle are checkpoints located? What are each responsible for checking? -
ANS G1- is growth factor present? Is the cell big enough? Is DNA undamaged?
G2- Is DNA replication complete? Is the DNA okay?
metaphase- Are chromosomes attached to kinetochore microtubules?
What are at each checkpoint determining if division should proceed? - ANS Regulatory
molecules.
What is apoptosis? - ANS The cell suicide pathway
What do growth factors do? - ANS Stimulate cells to divide
What are properties of normal cells? - ANS 1. Growth factors stimulate cells to divide
