G1 phase of cell cycle is absent in which cells?
Early cleavage stage cells
What happens to animal cytoplasm in the m-phase?
In the m-phase the cytoplasm is split by a cleavage furrow.
Is the first phase of mitosis in which chromosomes condense and spindle microtubules begin to form.?
the phase of mitosis when chromosimes are ligned in the middle of the cell
Which cytoskeletal proteins are important constituents of the contractile structures that form the cleavage furrows involved in animal cell cytokinesis?
Micro filaments form the cleavage furrow.Ring of filaments lay in the equator of the cell and its contraction forms the cleavage.
Indentation at the equator of a cell where it will divide?
cleavage furrow
G1 phase of cell cycle is absent in which cells?
Early cleavage stage cells
In what phase does the cleavage furrow appear?
A cleavage furrow forms during the Telophase phase. During the Metaphase phase chromosomes line up in the center of cell at the metal plate.
What is the name of the stage of development in vertebrates where cell differentiation begins and tissue layers first begin to form?
cleavage stage
What is the definition of G1 phase?
the first growth phase of the cell cycle consisting of the portion of Inter phase before DNA synthesis begin.
What process or phase follows telophase?
The phase occurring before the telophase in mitosis is the anaphase. In anaphase, the paired chromosomes separate and begin moving to opposite ends of the cell. At the end, each pole of the cell contains a complete compilation of chromosomes.
What happens during the G2 phase?
When DNA replication is completed, the cell enters the G2 phase. G2 phase is usually he shortest of the three phases of interphase. During the G2 phase, many of the organelles and molecules required for cell division are produced. When the events of the G2 phase are completed, the cell is ready to enter the M phase and begin the process of cell division.
What happens to animal cytoplasm in the m-phase?
In the m-phase the cytoplasm is split by a cleavage furrow.
How is the division of the cytoplasm different in the plants and animals?
Plants:A cell plate starts to form in the cleavage point.The cell plate eventually becomes a cell wall.Animals:During Telokinesis, the Cytoplasm starts to "pinch" at a cleavage point. Then, it splits.
Where is the equator of a cell?
the cleavage furrow
What phase do centromeres break and chromosomes begin migration toward opposite poles of the cell?
In anaphase, centromeres break and chromosomes begin migration toward opposite poles of the cell.
Which phase of reproduction does everything begin to line up before the cell can begin to split apart?
i can assure your wandering mind that the answer is metaphase. :}
Is the first phase of mitosis in which chromosomes condense and spindle microtubules begin to form.?
the phase of mitosis when chromosimes are ligned in the middle of the cell
