Question

Which of the following would be considered a transgenic organism?

1) a bacterium that has been treated with a compound that affects the expression of many of its genes
2) a fern grown in cell culture from a single fern root cell
3) all of the above
4) a human treated with insulin produced by E.coli bacteria
5) a rat with rabbit hemoglobin genes

Answer 1

A transgenic organism is an organism that contains genes from another organism inserted into its genome. In this case, a human treated with insulin produced by E.coli bacteria is an example of a transgenic organism. In this case, the insulin gene from humans is inserted into the E.coli bacteria, which then produces and secretes human insulin.

Step-by-step explanation:

A transgenic organism is an organism that contains genes from another organism that have been artificially inserted into its genome. Based on the given options, the transgenic organism would be option 4) a human treated with insulin produced by E.coli bacteria. In this case, the insulin gene from humans is inserted into the E.coli bacteria, which then produces and secretes human insulin.
