Is the best stage to count the number and study the morphology of chromosome?

Which stage is easiest to study morphology of chromosomes?

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.

At what stage are chromosomes counted?

Cells in metaphase are used in medical research to measure whether all of the chromosomes are present and whether or not they are all intact. This process of looking at chromosomes under the microscope is called karyotyping.

Which will be the best stage to count the number of chromosomes during mitosis briefly explain that stage?

At metaphase , the chromosomes are shortest and thickest. Therefore it is the best stage to observe the structure of chromosomes.

In which stage of the M phase the morphology of the chromosome can be best studied?

The best time to study chromosome size and shape is metaphase/late prophase.

Which stage of mitosis is best for studying chromosomes and why?

The chromosomes appear shortest and thickest during the metaphase and are arranged at the equator and form an apparent plate called as the equatorial or as the metaphase plate thus readily visible. Therefore, this phase is often chosen for karyotyping and for the chromosome analysis.

What stage 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.

Why is metaphase the best stage for the study of morphology of the chromosome?

The spindle tube collapses and forms a new nuclear membrane at each pole, which covers the chromosomes. The nucleus also reappears at each pole. So from the above point it’s clear that metaphase is the best stage to study the morphology of chromosomes.

What is the best stage in the cell cycle for chromosome analysis?

The best mitotic stage for chromosome analysis is prometaphase or metaphase. A typical metaphase chromosome consists of two arms separated by a primary constriction or centromere.
