cell cycle
what is a cell cycle
is the series of events that take place in a cell leading to duplication of its DNA and division of cytoplasm and organelles
What are some mitosis phases
prophase, metaphase, anaphase, and telophase.
What is Interphase
is the phase of the cell cycle in which a typical cell spends most of its life.
what are the phases of meiosis 1
Prophase 1, metaphase 1, anaphase 1, and telophase 1
what happens during meiosis 2
the sister chromatids within the two daughter cells separate, forming four new haploid gametes.
what are the 4 stages of the cell cycle
prophase, metaphase, anaphase, and telophase
What are spindle fibers
form a protein structure that divides the genetic material in a cell.
During interphase, DNA has replicated and appears as a loosely coiled mass known as ___________.
chromation
What happens during meiosis 1
divides twice to form four daughter cells.
what are the stages of meiosis 2
Prophase 2, metaphase 2, anaphase 2, and telophase 2
why is the cell cycle important
to organisms in different ways, but overall it allows them to survive.
what does anaphase do
they divide and each chromatid is pulled in an opposite direction
Is the nuclear membrane still intact during interphase?
yes
how many daughter cells are
four
what happens during prophase 2
the nuclear envelope breaks down and the spindle apparatus forms.
What happens in the cell cycle
To produce two similar daughter cells, DNA replication occurs during synthesis, and Gap
The process that results in new cells with genetic material that is identical to the original cell
mitosis
During interphase, ________________ is replicated.
DNA
what is the main goal of meiosis 1
to make daughter cells with exactly half as many chromosomes as the starting cell.
what happens during telophase 2
the chromosomes reach opposite poles
What is Prophase
is the first stage of cell division in both mitosis and meiosis.
The purpose of mitosis
the replacement of damaged cells or growth?
List the three parts of interphase in order.
gap, synthesis, and gap 2
what happens during prophase 1
During prophase I, they coil and become shorter and thicker
is interphase in meiosis 2
No
