Mitosis

Telophase

Cytokinesis occurs during _____ of mitosis.

S phase

DNA is replicated during the _____ phase of interphase.

Metaphase

During _____ of mitosis, chromosomes align at the cell's equator.

Prophase

During the _____ stage of mitosis, chromosomes condense and mitotic spindle fibers begin to form.

Reproductive cells

Meiosis occurs in _____ cells.

Anaphase

Microtubules begin to shorten in _____, pulling the chromosomes toward the centromere.

False, they result in four genetically unique daughter cells

True or False: Meiosis results in four identical daughter cells.

Two resulting cells after cytokinesis

What are daughter cells?

prophase, prometaphase, metaphase, anaphase, and telophase/cytokinesis

What are the five stages of mitosis?

The proteins that hold the centromeres degrade and the chromatids are liberated from one another, the chromosomes then move to opposite poles, via spindle fibers, with the centromere leading the way. Next, the spindles move apart from one another and the cell begins to elongate. As anaphase progresses, the chromosomes are pulled farther apart. Anaphase is the shortest of the mitotic stages.

What happens in anaphase?

is the continuation of telophase; in animal cells, a cleavage furrow is formed, pinching the cell in two. In plant cells, the cells are divided through the formation of a cell plate,

What happens in cytokinesis?

all of the chromosomes become aligned at the metaphase plate, and the centrosomes move to opposite poles of the cell, on either end of the mitotic spindle. Metaphase is the longest of the mitotic stages.

What happens in metaphase?

the nuclear envelope fragments and the microtubules surrounding the spindle enter the nuclear area and interact with, and attach to, the condensed chromosomes. The chromosomes attached to the mitotic spindles then begin to move toward the cell's equator.

What happens in prometaphase?

the chromosomes condense and become more tightly coiled, cytoskeleton disassembles, mitotic spindle fibers begin to form, nuclear envelope begins to break down

What happens in prophase?

nuclear envelopes are formed around each of the newly separated sets of chromosomes. The chromosomes, assembled at the poles of the cell begin to relax, and become less condensed. At this stage of mitosis, the nucleus is now divided into two identical nuclei.

What happens in telophase?

the cell increases in size and builds up energy reserves

What is G1 phase?

the central region where the two chromatids are bound together

What is a centromere?

the process where one cell splits from its sister cell

What is cytokinesis?

the longest part of the cell cycle. Interphase comprises 90% of the cell cycle

What is interphase?

two-stage process of cell division within the reproductive organs of sexually reproducing organisms. Through meiosis, a nucleus divides into four genetically distinct cells (daughter cells), each containing half the total number of chromosomes that were present in the original cell

What is meiosis?

cell division, occurring in nucleated cells, that results in daughter cells with identical chromosomes and organelles to the parent cell

What is mitosis?

composed of the centrosomes and extending microtubules.

What is mitotic spindle?

The phase mature, nondividing cells are in

What is the G0 Phase?

second phase of growth and energy acquisition

What is the G2 Phase?

DNA is replicated

What is the S Phase?

sequence of growth, DNA replication, growth and cell division that all cells go through

What is the cell cycle?

The cell's equator

What is the metaphase plate?

The original cell before cytokinesis

What is the parent cell?

Interphase

_____ comprises 90% of the cell cycle.
