During which phase are chromosomes still visible and the nucleus is intact?

Metaphase is a stage in the cell cycle where all the genetic material is condensing into chromosomes. These chromosomes then become visible. During this stage, the nucleus disappears and the chromosomes appear in the cytoplasm of the cell.

In which phase is the nucleus and nucleolus visible?

The DNA duplicates during interphase to prepare for mitosis (the next four phases that lead up to and include nuclear division). Chromosomes are not clearly discerned in the nucleus, although a dark spot called the nucleolus may be visible. Prophase.

What three phases are individual chromosomes no longer visible?

It is during interphase, telophase, and cytokinesis that the chromosomes are no longer visible.

What is S phase in cell cycle?

S phase is the period of wholesale DNA synthesis during which the cell replicates its genetic content; a normal diploid somatic cell with a 2N complement of DNA at the beginning of S phase acquires a 4N complement of DNA at its end.

Which is the correct order of cell cycle?

So the correct order of stages in the cell cycle is G1 → S → G2 → M. Some cells do not divide repeatedly and enter an inactive stage called G or quiescent stage after exiting G1.

What is uncoiled stringy DNA called?

What is uncoiled, stringy DNA called? It is called chromatin.

Which is the most variable stage of cell cycle?

Introduction to the Cell Cycle

G1 is typically the longest and most variable cell-cycle phase. When cells are “born” at cytokinesis, they are roughly half the size they were before mitosis, and during G1, they grow back toward an optimal size.
