Which chromosome encodes The D gene The A gene The B gene Th

Which chromosome encodes The D gene? The A gene? The B gene? The C gene?

Solution

1. the chromosome 1 encode D gene as from the above picture the D gene is expressed all over as chromosome 1 is present in all rest chromosomes are absent in one or the other cell line but still the D gene is encoded

2. the A gene is encoded by chromosome 5 since in cae of cell line 23, the A is not expressed in presence of 1,2,3,4 chromosome and in case of cell line 34 the presence of either 5 or 6 chromosome expresses A gene but in cell line 416 chromosome is absent thus chromosome 5 is the answer

3. the B gene is encoded by the chromosome 3 as in cell line 21 all cell line 1,2,3,4, are present and B gene is expressed but in cell line 34 the presence of 1, 2 chromosome shows negative gene B expression thus 1 and 2 goes out of list . tand in cell line 41 the chromosome 4 is absent and chromosome 3 is present and th B gene is expressed thus the answer is chromosome 3

4. the gene C is expressed by the chromosome 8 since it is absent from all cell lines and thus is not expressed in any of the cell line.
