∙ 13y agoIn prophase, chromatin fibers condense tightly into chromosome pairs. The centrosomes move away from each other and spindle microtubules grow from them; in other words, the mitotic spindle begins to form.

When does the nucleolus begin to fade away?
Prophase.
The first phase of mitosis is called?
The first stage of mitosis when chromosomes start becoming visible in the microscope is called prophase.
What stage occurs when crossing over occurs in meiosis?
Prophase I of Meiosis.
What is the phase that two new nuclear envelopes form?
In the Prophase. Nuclear envelope and nucleolus disappears.
During which phase does the chromatin condense into chromosomes?
The chromosomes coil up and condense during prophase
What stage does chromatin condense to chromosomes?
During mitosis, chromosomes are in their most condensed form during metaphase
What is the difference between prophase mitosis and prophase meiosis?
In prophase I of meiosis, crossing over of homologous chromosomes occurs. This does not happen in prophase of mitosis.
What are the first steps in mitosis?
Prophase: The condensation of chromosomes; the nuclear membrane disappears; formation of the spindle apparatus; chromosomes attach to spindle fibers.
Does meiosis 2 have a prophase stage?
Yes, it does, only it is called prophase 2 or prophase II.
In what stage do the centrioles move apart?
The centrioles begin to move apart in the Prophase.
During which phase of meiosis do tetrads line up in the middle of the cell?
Tetrads line up in the middle of the cell during metaphase I.
In prophase do the nuclear membrane dissapears?
late Prophase
