semester 1 exam part 5 Flashcards
equally divides an animal cell into two offspring cells
cleavage furrow
equally divides chromatids between offspring cells
mitotic spindle
the period during which DNA is copied
S phase
the time between cell divisions
interphase
the first phase of interphase
G1 phase
the phase of mitosis during which chromosomes move to opposite poles
anaphase
prokaryotic cells reprodue by a process called
binary fission
in eukaryotic cells, DNA is copied during a phase of the cell cycle called
S phase
the cytoplasm of a euykaryotic cell divides by
cytokinesis
the fibers that extend from centrosome to centrosome during mitosis are
polar fibers
structure that forms along the mid line of a dividing plant cell
cell plate
during mitosis and meiosis , kinetochore fibers are though to
move chromosomes
histones are proteins that
aid in the packing of DNA in eukaryotic cells
DNA that is uncoiled and spread out
chromatin
the chromosomes of most prokaryotes consist of proteins and
a single circular DNA moleucle
during cell division ,the DNA in a eukarytoic cell is tightly packed and coiled into structures called
chromosomes
the repeating set of events that make up the life of a cell
cell cycle
a region of the chromosome where two sister chromatids are held together
centromere
the region of a cell between the cell membrane and the nucleus
cytoplasm
a dark body containing a centriole in animal cells; spindle fibers radiate from this structure in preparation for mitosis
centrosome
DNA in a coiled rod shaped form that occurs during cell division
chromosome
structure that appears during mitosis in animal cells
centrioles
one of two identical parts of a chromosome
chromatids
the DNA in the nucleus of a nondividing cell
chromatin
the production of mature egg cells
oogenesis
reproductive cell
gamete
the scientific study of hereditary is called
genetics
the father of genetic is
gregor mendel
mendel obtained the P generation by allowing the plants to
self pollinate
the inheritance of one trait had no effect on the inheritance of another became known as the
law on independent assortment
