bt Flashcards
The process of
“crossing over ”
takes place
during this
stage.
pachytene
The spindle fibers will
disappear and nuclear
membrane will
reappear
telophase
The chromosome
is made up of two
long threads of
sister chromatids
as a result of
replication during
the S phase of
the cell cycle
leptotene
Nuclear envelope
breaks down
prophase
The chromatins condenses
become double stranded &
connected at the
“centromere”
prophase
The homologous
chromosome pairs
begin to separate
and move away from
one another except
at chiasmata.
diplotene
The homologous
chromosomes
begin to pair off in
a process called
“Synapsis” and
will be called
“Tetrad ”.
zygotene
The chromosomes
arrived at opposite
poles and begin to
uncoil.
telophase
The spindle fibers will pull
the chromatids away
from each other so they
will separate into single
stranded chromosomes
ANAPHASE
The paired
chromosomes
are fully
condensed and
disperse in the
nucleus.
diakinesis
The chromosomes will
go to their opposite
poles
anaphase
This is a type of cell
division of germ cells
in sexually reproducing
organisms that
produces gametes,
where a single cell
divides twice to
produce four cells
meiosis
The chromatids align
themselves at the
metaphase plate.
metaphase
The Spindle fibers
that were growing is
now attached to the
“kinetochore” of the
sister chromatids.
