Chromosomes first become visible during which phase of mitosis?

Chromosomes first become visible during prophase of mitosis when they condense and coil up tightly. This allows them to be easily seen under a microscope as separate structures.

What stage of mitosis do Chromsomes first become visible?

What structure will the chromatin become in mitosis?

The chromatin in the cell becomes chromosomes in prophase, the first stage of mitosis. The chromatin coils tightly together to form into separate chromosome strands during this phase.


What is the the mitosis stage when the chromatids are visible?

It is during the prophase when chromatids become visible. Prophase is the first as well as the longest stage of mitosis.


When do chromosomes become visible in the nucleus of a cell?

During prophase, the first stage of mitosis, the chromosomes become visible as distinct structures. The nuclear envelope also now breaks down, and a spindle forms.


What is the first step in eukaryotic DNA replication?

1.) The 2 copies of DNA produced by replication in each chromosome remain closely associated until the cell enters prophase of mitosis. 2.) At that point, the chromosomes condense, and the two chromatids in each chromosome become clearly visible. 3.) They separate from each other in anaphase os mitosis, producing 2 cells, each with a complete set of genes coded in DNA.


What is the definition of prophase?

Prophase is the first step in Mitosis (part of interphase) and it's when the chromatid pairs become visible and the spindle is beginning to form.

The first phase of mitosis is called?

The first stage of mitosis when chromosomes start becoming visible in the microscope is called prophase.


The phase of mitosis where the chromatin fibers duplicate and condense into visible chromosomes is the?

The phase of mitosis where the chromatin fibers duplicate and condense into visible chromosomes is Interphase. Interphase is the first stage of the cell cycle.


Which phase do chromosomes first become visible?
