Human cells from a patient with a deficiency in HGPRT are fused with mouse cells that are deficient in HGPRT. The hybrid cells are grown in HAT medium, and the following results are obtained:
- Clone 1: X, 2, 3 | +
- Clone 2: 5, 7, 11 | –
- Clone 3: X, 5, 12 | +
| Hybrid Cell Clone | Human Chromosomes Present | HGPRT Activity |
|---|
Which human chromosome is likely to carry the HGPRT gene, according to Mapping by using somatic cell hybrids For CSIR NET?
