Question

Including the sex chromosomes, the chromosome number of a normal human cell is ___________ and the chromosome number of this HeLa cell is (look at picture). (Hint: Chromosome number is different from total chromosome count.)

Transcribed Image Text:The image displays a karyotype, which is an organized profile of a person's chromosomes. This specific karyotype shows 22 pairs of autosomes and one pair of sex chromosomes, totaling 23 pairs. Each pair of chromosomes is numbered from 1 to 22 and is arranged according to size, with chromosome 1 being the largest. The 23rd pair is labeled as X/Y, indicating that it represents the sex chromosomes. This particular karyotype depicts a male, as it includes both an X and a Y chromosome. The chromosomes are stained to show a banding pattern, which provides a way to identify structural features and any potential abnormalities. These patterns are crucial for genetic analysis and can be used to diagnose genetic disorders. Each chromosome pair typically appears as two similar, elongated structures that are aligned next to each other.
