The New Monsanto Way: Cros*****reed the plants.讓植物自己當轉基因專家了~~.
The Old Way
Identify plants with recognizable, desirable traits.
Cros*****reed those plants together.
Grow the offspring.
Wait to see if the traits show up. Repeat as necessary.
The Genetic Modification Way
Identify plants or other organisms with recognizable, desirable traits.
Isolate the genes that manifest those traits.
Use enzymes to clip out those genes and paste them into the genomes of other plants, or inject them using a “gene gun” (for real) or by piggybacking them on a bacteria or virus.
Grow the plant with the inserted gene. If the gene has successfully incorporated into the plant, you’ll have a novel phenotype.
The New Monsanto Way
Identify plants with recognizable, desirable traits.
Cros*****reed the plants.
Sift through the offspring genome for known markers for desirable traits.
Grow only the plants with those markers.
