Eventually cells need to duplicate. There are two main methods of replication, mitosis and meiosis. This tutorial will talk about mitosis.

The big idea to remember is that mitosis is the simple duplication of a cell and all of its parts. It duplicates its DNA and the two new cells (daughter cells) have the same pieces and genetic code. Two identical copies come from one original. Start with one; get two that are the same.

Do homologous chromosomes pair up during metaphase 2 as they do in metaphase 1?

No, homologous chromosomes do not pair up during metaphase 2 as they do in metaphase 1. In metaphase 2, individual chromosomes line up along the metaphase plate.


What is is the difference between metaphase 1 and 2?

Metaphase 1 The chromosomes line up on the equatorial (metaphase) plate. Metaphase 2 Kinetochores of the paired chromatids.


During what phase of meiosis do replicated homologous chromosomes line up next to each other at the cell's equator-?

It is during the anaphase of meiosis that the replicated homologous chromosomes line up next to each other at the cell's equator.


What is the function of the centriole pair?

It organizes the microtubules in mitosis. The microtubules move the chromosomes around the cell during mitosis, most importantly lining the chromosomes up at the metaphase plate in metaphase so that they can split up into the two daughter cells.


Bivalents align at metaphase plate?

Metaphase 1


During metaphase II, do homologous chromosomes pair up as in metaphase I?

No, during metaphase II of meiosis, homologous chromosomes do not pair up as they do in metaphase I. Instead, individual chromosomes line up along the metaphase plate.


How does metaphase in meiosis differ from metaphase in mitosis?

In metaphase of meiosis, homologous chromosomes line up in pairs, while in metaphase of mitosis, individual chromosomes line up singly.


Differences between metaphase 1 and metaphase 2?

Which phase is known as the organization phase in mitosis?

Metaphase!


What phase are the chromosomes lined up on the equatorial plate?

The chromosomes are lined up at the equatorial plate during metaphase of mitosis and metaphase II of meiosis. This alignment ensures that each chromosome is properly attached to the spindle fibers before they separate and move to opposite poles.


How many chromosomes are in metaphase?

Metaphase I or Metaphase II? In metaphase I it would have 24. In metaphase II it would have 6.
