Gene therapy is the introduction of genes into existing cells to prevent or cure a wide range of diseases. For example, suppose a brain tumor is forming by rapidly dividing cancer cells. The reason this tumor is forming is due to some defective or mutated gene.ene therapy is revolutionizing the world of medicine. Many physicians are predicting that in twenty years gene therapy may change the practice of medicine from a treatment-based to a prevention-based practice. Our future is l ocked away inside of our genes. Gene therapy is unlocking these doors.
Excel's INDEX function is a powerful function when you want to find a value in a specific row and column location inside a table of data. Our examples used numeric values to identify the row and column values that INDEX should work with.
The difference is illustrated below. The other key difference is that INDEX MATCH formulas work as a right to left lookup, whereas VLOOKUP only works left to right. As you can see in the example below, I can use INDEX MATCH to lookup a value that is to the right of my return value using INDEX MATCH.When we combine both the INDEX formula and the MATCH formula, the number that the MATCH formula returns becomes the row number for your INDEX formula. =INDEX (array, MATCH formula). Below is an example of using the INDEX MATCH to return âProduct Typeâ for our lookup value.As you can see, it returns the same value we got from VLOOKUP.INDEX (array, row number). Below is an example of using INDEX to return the value âShirts,â assuming that you already know that the value is three cells down on your defined array. (you also have the option to specify column number, but that isnât relevant in a basic INDEX MATCH formula).
