What chromosome number the gene for B is located?
A somatic cell hybridization experiment was performed and three hybrid cell lines were produced (23, 34, and 41). In each line, the chart shows which human chromosomes remained. The far right of the table shows + if the gene product of gene A, B, and C is present in the cells.
The correct answer to this question is 3. Chromosomes are DNA molecules, which house an organism's genetic materials. These materials including packaging and chaperone proteins. The definitive discovery of chromosomes came in the mid 1880s from scientist Theodor Boveri. Chromosomes can be viewed under a light microscope, but they can only be viewed when the cell is going trhough the metaphase of cell divison.
The recombination of chromosomes during meiosis and sexual reproduction have a vital role in the diversity of genetics. Humans have a total of 46 chromosomes, for each cell containts 23 pairs. Autosomes are twenty-two of the pairs, while the twenty-third pair is called a sex chromosome.
