Metaphase is the best stage to count the total number of chromosomes in any species and to establish a detailed study of the morphology of the chromosomes. As mitotic cells are easy to obtain, morphological studies are generally based on mitotic metaphase chromosomes.
Which phase 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.
Which stage is best for study of chromosome?
Metaphase is the best stage to count the number of chromosomes and study their morphology.
During which stage of mitosis cycle morphology is most easily studied?

Assertion :- Morphology of chromosomes is most studied during metaphase of cell division.
In which phase of the M phase the morphology of the chromosome can be best studied?
In metaphase, the chromosomes are clearly visible and each chromosome has two chromatids. Hence , the morphology of chromosomes can be best studied during metaphase.
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.
Which of the following phases of cell cycle size of chromosomes is best studied?
Complete step by step answer:One of the best cell division stages to observe the shape, size and the numbers of chromosomes is the metaphase.
Which is the shortest phase of mitosis?
In anaphase, the shortest stage of mitosis, the sister chromatids break apart, and the chromosomes begin moving to opposite ends of the cell.
Which is the best stage to see the shape of chromosome according to position of centromere?
Ø The centromere is located exactly at the centre of the chromosome. Ø Thus, these chromosomes will have two equal sized arms. Ø The metacentric chromosomes will appear as ‘V’ shaped structures in the metaphase stage of cell division.
Which stage of cell division will you select to study the morphology of chromosomes?
Metaphase is the best stage to study the morphology of chromosomes….
What is the morphology of chromosome?
1. CHROMOSOME Chromosomes are the rod-shaped ,filamentous bodies present in the nucleus, which become visible during cell division. They are carriers of the gene or unit of heredity. Chromosome are not visible in active nucleus due to their high water content , but are clearly seen during cell division.
Which is the longest phase of M phase?
So clearly, the longest phase of the Mitosis is Prophase.
What happens in S phase?
S phase. In S phase, the cell synthesizes a complete copy of the DNA in its nucleus. It also duplicates a microtubule-organizing structure called the centrosome. The centrosomes help separate DNA during M phase.
What are the 4 stages of the cell cycle?
In eukaryotes, the cell cycle consists of four discrete phases: G1, S, G2, and M. The S or synthesis phase is when DNA replication occurs, and the M or mitosis phase is when the cell actually divides. The other two phases — G1 and G2, the so-called gap phases — are less dramatic but equally important.
