It is during the prophase in which chromosomes first appear to be duplex structures.Each cell in a person typically has 23 pairs of chromosomes.
The chromosomes become different from each other due to crossing over which occurs during prophase I.
In interphase the chromosomes are not yet visible but become visible in prophase
Prophase is inside the nucleus the chromosomes get short and thick and as they coil up become visible as pairs attached by the centromere. The centromere is joined to special proteins to from the kinetochore.
the 5th phase
double chromosomes first become visible in which step of mitosis?
Interphase as they become decondenced
metaphase
Duplicated chromosomes first become visible during prophase.
It is during the prophase in which chromosomes first appear to be duplex structures.Each cell in a person typically has 23 pairs of chromosomes.
Prophase
Chromosomes first become visible during prophase of mitosis when they condense and coil up tightly. This allows them to be easily seen under a microscope as separate structures.
During prophase, the first stage of mitosis, the chromosomes become visible as distinct structures. The nuclear envelope also now breaks down, and a spindle forms.
Interphase and Telophase
During the Prophase. :)Chromosomes become highly condensed.They are visible to light microscope,not naked eye
in the late prophase this phenomenon occur
The chromosomes become different from each other due to crossing over which occurs during prophase I.
