1. genetic engineering is when a gene expressing a trait is removed from one organism and placed in the other so that the animal can express that gene, example (a tomato is fat and a cucumber is tall, genetic engineering is taking the gene in the tomato that makes it fat and placing it in the cucumber so that it can become fat)
2. DNA is the expresser for all your traits, it is present in all your cells, and it has instructions for genetic coding, protein making, etc. dna is compressed into chromosomes and every cell in your body has 48 chromosomes except for two cells, which are the egg and the sperm as they have 24 cells each.
