during which stage of mitosis does the nucleolus disappear? course hero

by Prof. Lila Kshlerin 6 min read

During prophase, the chromosomes condense, the nucleolus disappears, and the nuclear envelope breaks down.

In which phase of prophase 1 does the nucleolus disappear?

So, the correct answer is 'Diakinesis'.

In which phase of meiosis II does the nucleolus disappear?

In prophase II, once again the nucleolus disappears and the nucleus breaks down. The chromatin condenses into chromosomes. The spindle begins to reform as the centrioles move to opposite sides of the cell.Dec 5, 2014

During which phase of mitosis is a nucleolus plainly visible?

In prophase, the nucleolus disappears and chromosomes condense and become visible. In prometaphase, kinetochores appear at the centromeres and mitotic spindle microtubules attach to kinetochores.

During which stage of mitosis does the nucleus dissolve?

ProphaseExplanation: Prophase is the first stage of mitosis, during which the cell begins to position itself in order to separate the chromatids and divide. During prophase, the nuclear envelope and nucleolus are dissolved and the chromosomes condense.

Why does nucleolus disappear during mitosis?

Chromosome Condensation DNA in this highly condensed state can no longer be transcribed, so all RNA synthesis stops during mitosis. As the chromosomes condense and transcription ceases, the nucleolus also disappears.

In what phase does the nucleolus reappear?

Telophase is the final step of mitosis. During this phase, the nuclear membrane reforms, the nucleolus reappears, and the chromosomes unravel into chromatin.

What happens to nucleolus during metaphase?

At metaphase, the mitotic spindle formed a broad band completely embedded within the nucleolus. The nucleolus separated into two discreet masses connected by a dense band of microtubules as the spindle elongated.Apr 6, 2012

What happens during metaphase of mitosis?

Metaphase is a stage during the process of cell division (mitosis or meiosis). Usually, individual chromosomes cannot be observed in the cell nucleus. However, during metaphase of mitosis or meiosis the chromosomes condense and become distinguishable as they align in the center of the dividing cell.

During what stage does G1 S and G2 phase happen?

Interphase is composed of G1 phase (cell growth), followed by S phase (DNA synthesis), followed by G2 phase (cell growth). At the end of interphase comes the mitotic phase, which is made up of mitosis and cytokinesis and leads to the formation of two daughter cells.

During which phase of mitosis do the nuclear membrane nucleolus and nucleus dissolve quizlet?

prophase, metaphase, anaphase, telophase (1 and 2). Just like in mitosis, during prophase, DNA condensation occurs, the nuclear envelope and nucleoli disappear, and the spindle starts to form.

During which phase of mitosis do the nuclear membrane nucleolus and nucleus dissolve Brainly?

During prophase of mitosis the nuclear membrane, nucleolus, and nucleus dissolves.Oct 17, 2018

During which phase of mitosis do the nuclear membrane nucleolus and nuclear us?

prophaseThe first phase of mitosis- in prophase nuclear membrane nuclolus and neucleus starting to dissolve.In the late prophase(at the end of prophase) when the condensation of chromosome completed,at that time all thepart mention above dissolve.Mar 23, 2018
