Question

The best stage to count the number of chromosomes during mitosis is or structure of chromosomes can be best seen at

a. prophase
b. metaphase
c. anaphase
d. telophase​

Answer 1

$\rm Answer -$

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

━━━━━━━━━━━━

$\bf Metaphase -$

$\implies$In this stage, the chromosomes are attached to spindle fibres that arises from each pole and lie at equator. After reaching equator ,the chromosomes align at equator forming a metaphasic plate.

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

b) Metaphase.

• Metaphase are chromosomes which are chosen for the chromosome analysis.
• Metaphase chromosomes are commonly visible.
• Condensation of cell division is complete in metaphase.
• It is the stage of cell divison i.e. Miosis or mitosis.
• It is in the eukaryotic cells.
• Metaphase chromosomes carries the genetic information.
• Centromeres of the chromosomes convene themselves on the metaphase plate in the terms of metaphase.
• Metaphase is characterized by the lining of the chromosomes along the ‘metaphase plates’.
