Please fully answer questions 3 & 4. Thank you so
much!

3. We originally thought there were about 100,000 genes in humans because that is about the number of proteins (including enzymes) we have discovered. However, the human genome project demonstrated that there are actually only about 20,000 genes on human chromosomes. Recall what you know from the last lesson (hint introns and exons) to explain in a paragraph how this might be possible? Why is this important to know when considering using biotechnology to engineer genes? 4. Describe three uses of genetic engineering in agriculture. In one or two sentences for each describe the benefits and some potential problems? (Note that Figure 10.10 is misleading the corn cobs shown are all natural races of maize found in Mexico where corn evolved. This illustrates the amount of natural variation that is available both for traditional breeding and/or genetic engineering.)
