Frequent question: Which state is best to count the number and study chromosome morphology?

Metaphase is the best phase to count total number of chromosomes in any species and detailed study of morphology of chromosome. Idiogram (arrangement of chromosomes in a series of decreasing length) can be drawn in the stage.

Which phase is easiest to study morphology of chromosomes?

In simplewords, as the chromosomes are in condensed state and get stained completely in the metaphase stage, so it is easy to study the morphology of chromosomes in this stage.

Which is the best stage to count the number of chromosomes during mitosis?

Metaphase is the stage at which we can observe the number and structure of chromosomes the best.

At what state are chromosomes most easily counted and why?

Answer: 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.

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.

In which phase we can count chromosomes?

Explanation: In anaphase, the pairs of sister chromatids separate and are now individual chromosomes. In anaphase, we can see the individual chromosomes moving to opposite poles of the cell. You can count the chromosomes at this point if you have high enough magnification.

Which stage is best to count the number?

Metaphase is the best phase to count total number of chromosomes in any species and detailed study of morphology of chromosome. Idiogram (arrangement of chromosomes in a series of decreasing length) can be drawn in the stage.

In what stage does the nucleus size increase?

The nucleus increases in size from the time of its formation, immediately following NE assembly, to when it reaches its final size in interphase.
