Question

What is the chromosome number of this HeLa cell?

 

(Hint: Chromosome number is different from total chromosome count.)

The image displays a complete human karyotype, a visual representation of the chromosomes in a cell. The chromosomes are arranged and numbered according to size, from largest to smallest, numbered 1 through 22, followed by the sex chromosomes (X and Y). 1. **Chromosomes 1–22**: These are autosomes, and they are organized in pairs, with each pair showing two nearly identical chromatids. 2. **Sex Chromosomes**: The image shows an X chromosome, indicating this is likely a female karyotype (XX for females, XY for males). The chromosomes are stained to show the distinct banding patterns which help identify structural features and ensure each chromosome is appropriately classified. Karyotyping is often used in genetics and medicine to diagnose chromosomal abnormalities, such as Down syndrome or Klinefelter syndrome.
