A panel of cell lines was created from human-mouse somatic-cell fusions. Each line was examined for the presence of human chromosomes and for the production of three enzymes. The following results were obtained. (FIGURE CANNOT COPY) On the basis of these results, give the chromosome location of enzyme $1,$ enzyme $2,$ and enzyme 3

Key Concepts

Somatic Cell Hybridization

This technique involves fusing two different types of cells, typically from different species, to create hybrid cells that contain nuclei with chromosomes from both sources. It is used to segregate and analyze specific chromosomes, as the hybrid cells selectively lose or retain particular chromosomes over time, allowing researchers to link genetic traits to specific chromosomes.

Chromosome Mapping

Chromosome mapping is the process of determining the location of genes on a chromosome. By examining which human chromosomes are present in the hybrid cells and correlating them with the expression of particular genes or enzymes, researchers can identify the chromosomal location that carries the gene responsible for each enzyme.

Correlation Analysis for Gene Localization

This method involves comparing the presence or absence of phenotypic traits, such as enzyme production, with the presence or absence of individual chromosomes within a panel of hybrid cell lines. A close correlation between a specific human chromosome and the production of an enzyme indicates that the gene encoding that enzyme is located on that chromosome.
