BIOS 251 Exam 2 ACTUAL EXAM Questions and
Answers |Latest 2023-2024 – Chamberlain
UNIVERSITY GRADE A.
Cell division in which the nucleus divides into nuclei containing the
same number of chromosomes - ANSWER >>> Mitosis
The resting phase of mitosis. Cell grows, performs its normal
functions, and prepares for division; consists of G1, S, and G2 phases
- ANSWER >>> Interphase
Cells that have left the cycle and cease dividing for a long time (or
permanently) - ANSWER >>> G Zero (G0) Phase
The first gap, or growth phase, of the cell cycle, consisting of the
portion of interphase before DNA synthesis begins. - ANSWER >>>
G1 Phase
The synthesis phase of the cell cycle; the portion of interphase during
which DNA is replicated. - ANSWER >>> S Phase
The second gap, or growth phase, of the cell cycle, consisting of the
portion of interphase after DNA synthesis occurs.
Growth and preparation for mitosis - ANSWER >>> G2 Phase
First and longest phase of mitosis, during which the chromosomes
become visible and the centrioles separate and take up positions on
the opposite sides of the nucleus - ANSWER >>> Prophase
Second phase of mitosis, during which the chromosomes line up
across the center of the cell - ANSWER >>> Metaphase
,The third phase of mitosis, during which the chromosome pairs
separate and move toward opposite poles - ANSWER >>> Anaphase
The final phase of cell division, between anaphase and interphase, in
which the chromatids or chromosomes move to opposite ends of the
cell and two nuclei are formed. - ANSWER >>> Telophase
Division of the cytoplasm during cell division - ANSWER >>>
Cytokinesis
Cell division that produces reproductive cells (gametes) in sexually
reproducing organisms - ANSWER >>> Meiosis
Compare and Contrast Mitosis and Meiosis - ANSWER >>> Mitosis
produces two diploid (2n) somatic cells that are genetically identical to
each other and the original parent cell, whereas meiosis produces four
haploid (n) gametes that are genetically unique from each other and
the original parent (germ) cell.
Number of Chromosomes in Humans... - ANSWER >>> 46
Haploid Number of Chromosomes In Humans - ANSWER >>> 23
Control center of the cell; a part of the cell containing DNA and RNA
and responsible for growth and reproduction - ANSWER >>> Nucleus
Processes and transports proteins made at attached ribosomes;
synthesizes phospholipids - ANSWER >>> Rough Endoplasmic
Reticulum (RER)
Fatty acid and steroid synthesis; detoxifies toxic substances -
ANSWER >>> Smooth Endoplasmic Reticulum (SER)
A cell organelle that helps make and package materials to be
transported out of the cell - ANSWER >>> Golgi Complex
, Cell organelle filled with enzymes needed to break down certain
materials in the cell - ANSWER >>> Lysosomes
Produce hydrogen peroxide, detoxifies harmful substances, oxidizes
fatty acids, and protects cell from free radicals - ANSWER >>>
Peroxisomes
- Hollow, cylindrical organelle that disposes of unnecessary and
damaged proteins
- Contain enzymes that break down tagged, targeted proteins into
short peptides and amino acids - ANSWER >>> Proteasomes
- Located near the nucleus and help to organize cell division
- Form mitotic spindle during mitosis - ANSWER >>> Centrioles
A structure in cells containing two centrioles from which the spindle
fibers develop and organized - ANSWER >>> Centrosome
Point of growth for cilium or flagellum - ANSWER >>> Basal Body
Cell component responsible for energy production; powerhouse of the
cell - ANSWER >>> Mitochondria
Organelle responsible for protein synthesis - ANSWER >>>
Ribosomes
Network of protein filaments that aid in intracellular support, cell
movement, and moves organelles. - ANSWER >>> Cytoskeleton
The basic unit of structure and function in all living things.
Composed of plasma (cell membrane), cytoplasm, cytosol, nucleus,
and cytoskeleton - ANSWER >>> Cells
Clear gel within the cell sometimes referred to as intracellular fluid
(ICF) - ANSWER >>> Cytosol
