BIOS-251 Exam 2 with Questions and
Correct Answers 100% Pass
Cell division in which the nucleus divides into nuclei containing the same
number of chromosomes - CORRECT ANSWERS Mitosis
The resting phase of mitosis. Cell grows, performs its normal functions, and
prepares for division; consists of G1, S, and G2 phases - CORRECT ANSWERS
Interphase
Cells that have left the cycle and cease dividing for a long time (or permanently)
- CORRECT ANSWERS G Zero (G0) Phase
The first gap, or growth phase, of the cell cycle, consisting of the portion of
interphase before DNA synthesis begins. - CORRECT ANSWERS G1 Phase
The synthesis phase of the cell cycle; the portion of interphase during which
DNA is replicated. - CORRECT ANSWERS 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 - CORRECT ANSWERS 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 - CORRECT ANSWERS Prophase
Second phase of mitosis, during which the chromosomes line up across the
center of the cell - CORRECT ANSWERS Metaphase
The third phase of mitosis, during which the chromosome pairs separate and
move toward opposite poles - CORRECT ANSWERS 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. - CORRECT ANSWERS Telophase
Division of the cytoplasm during cell division - CORRECT ANSWERS
Cytokinesis
, Cell division that produces reproductive cells (gametes) in sexually
reproducing organisms - CORRECT ANSWERS Meiosis
Compare and Contrast Mitosis and Meiosis - CORRECT ANSWERS 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... - CORRECT ANSWERS 46
Haploid Number of Chromosomes In Humans - CORRECT ANSWERS 23
Control center of the cell; a part of the cell containing DNA and RNA and
responsible for growth and reproduction - CORRECT ANSWERS Nucleus
Processes and transports proteins made at attached ribosomes; synthesizes
phospholipids - CORRECT ANSWERS Rough Endoplasmic Reticulum (RER)
Fatty acid and steroid synthesis; detoxifies toxic substances - CORRECT
ANSWERS Smooth Endoplasmic Reticulum (SER)
A cell organelle that helps make and package materials to be transported out of
the cell - CORRECT ANSWERS Golgi Complex
Cell organelle filled with enzymes needed to break down certain materials in the
cell - CORRECT ANSWERS Lysosomes
Produce hydrogen peroxide, detoxifies harmful substances, oxidizes fatty
acids, and protects cell from free radicals - CORRECT ANSWERS 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 - CORRECT ANSWERS Proteasomes
- Located near the nucleus and help to organize cell division
- Form mitotic spindle during mitosis - CORRECT ANSWERS Centrioles
A structure in cells containing two centrioles from which the spindle fibers
develop and organized - CORRECT ANSWERS Centrosome
Point of growth for cilium or flagellum - CORRECT ANSWERS Basal Body
Cell component responsible for energy production; powerhouse of the cell -
CORRECT ANSWERS Mitochondria
