Campbell Biology Chapter 12 Test Questions and Answers
Rated A
cell division - -the process in reproduction mitosis - -part of eukaryotic cell division
and growth by which a cell divides to form during which the cell nucleus divides
daughter cells
cytokinesis - -division of the cytoplasm
cell cycle - -series of events in which a cell during cell division
grows, prepares for division, and divides to form
two daughter cells
Walther Flemming - -German scientist who
in 1882 developed dyes that allowed him to
genome - -all the DNA in one cell of an observe the behavior of chromosomes during
organism mitosis and cytokinesis,
chromosome - -a threadlike body in the M phase - -the phase in the cell cycle
cell nucleus that carries the genes in a linear where mitosis and cytokinesis occur resulting in
order cell division, the shortest part of cell cycle
chromatin - -the substance that composes interphase - -the period of the cell cycle
eukaryotic chromosomes; it consists of specific during which activities such as cell growth and
proteins, DNA, and small amounts of RNA protein synthesis occur without visible signs of
cell division - about 90% of cell cycle
somatic cell - -cell that makes up all of the
body tissues and organs, except gametes G1 phase - -The first gap, or growth phase,
of the cell cycle, consisting of the portion of
interphase before DNA synthesis begins.
gametes - -reproductive cells, sperm cells
and egg cells
S phase - -The synthesis phase of the cell
cycle; the portion of interphase during which DNA
sister chromatids - -Replicated forms of a is replicated.
chromosome joined together by the centromere
and eventually separated during mitosis or
meiosis II. G2 phase - -stage of interphase in which
cell duplicates its cytosol and organelles
centromere - -a specialized condensed
region of each chromosome that appears during prophase - -first and longest phase of
mitosis where the chromatids are held together mitosis in which the genetic material inside the
to form an X shape nucleus condenses and the chromosomes
become visible
