Meiosis produces this many cells
what is 4
Most cells spend the majority of their lives in this specific phase of Interphase.
What is G0 (Gap Zero)
In this first stage of mitosis, these structures migrate to opposite poles and chromatin begins to condense.
what is centrosomes
These are the two identical sides of a duplicated chromosome
What are sister chromatids?
When the cytoplasm pinches apart at the end of telophase it is called this.
What is cytokinesis?
The purpose of this process is to create cells for sexual reproduction.
what is meiosis
During this specific sub-phase of Interphase, the cell creates two identical copies of each chromosome
What is S Phase
This stage is often called the "reverse of prophase" because nuclear membranes reform and chromosomes decondense
What is telophase?
This is the specific region of the chromosome where two sister chromatids are connected.
What is the centromere?
Because of their rigid cell walls, plant cells must form this structure made of vesicles to divide
What is a cell plate?
During this phase, tetrads line up at random, promoting genetic variation
what is metaphase I
Neurons and other cells that stop dividing in adulthood are said to have entered this "resting" state.
What is G0 (Gap Zero)
The purpose of this process is for growth and repair.
what is mitosis
This organelle, consisting of a centriole pair and surrounding proteins, is responsible for organizing microtubules.
What is the centrosome?
When a cell only has half the compliment of chromosomes it is said to be this.
What is haploid?
During synapsis, DNA is swaped between homologous chromosomes. This process leads to genetic variation.
what is crossing-over
occurs during G2 to ensure daughter cells do not inherit mutations.
What is checking for replication errors
This "fifth stage" occurs when the nuclear membrane is almost gone, allowing spindle fibers to attach to kinetochores.
What is prometaphase?
These structures line up along the equatorial plate during metaphase I
What is tetrads?
Prometaphase occurs when the nuclear membrane is almost gone, allowing spindle fibers to attach to these structures
what is kinetochores
This happens in anaphase II of meiosis and leads to “mistakes” in chromosome count of gametes.
what is nondisjunction?
During G2, the cell rapidly synthesizes these specific proteins to prepare for the sorting of chromosomes.
What are spindle fiber proteins?
In this phase of mitosis, spindle fibres pull sister chromatids to opposite poles of the cell.
What is anaphase
This network of kinetochore, polar, and astral structures are collectively known by this name.
What are the spindle fibers
This structure forms in animal cells to constrict the cell membrane in the middle and divide the cytoplasm.
What is a cleavage furrow
