Careful observation is the key.
You can tell a chromosome has doubled because of the DNA's strands. They coil very tightly.
the answer is CHROMOSOME your very welcome
TRUE
Just before cell division begins,the amount of DNA doubles and so do the chromosomes.Each doubled chromosome consists of two copies of the original chromosome joined at the center
The doubled rod of condensed chromatin is known as a chromosome. Chromosomes are tightly packed structures of DNA and protein that contain the genetic information of an organism. During cell division, chromosomes condense further to facilitate separation and distribution of genetic material to daughter cells.
Doubled stranded DNA and protein molecules
This is known as polyploidy, where cells have extra sets of chromosomes. Polyploidy can occur naturally or be induced experimentally, and it can lead to changes in an organism's characteristics and traits. This phenomenon is commonly observed in plants.
Each chromosome in a doubled or replicated pair is referred to as a "sister chromatid." During cell division, each chromosome replicates to form two sister chromatids that are identical copies of each other, connected at a region called the centromere. These sister chromatids separate during mitosis or meiosis to ensure that each daughter cell receives an identical set of chromosomes.

Diakinesis is the last stage of prophase during meiosis. Diplonema is the doubled form of the chromosome strand during the diplotene stage of meiosis.
During meiosis, sex cells form when chromosome pairs are separated from each other into different cells during the first division (meiosis I) and sister chromatids are separated from each other during the second division (meiosis II). This process results in the formation of haploid cells that have half the number of chromosomes as the original parent cell.
