Wolves, corns, and bananas, what do they all have in common? Selective breeding. It’s a process by which humans can select desirable traits less precisely than methods used today. For example, dogs weren’t the lovely creatures that we have today. Rather, they were vicious scavengers, quite hostile to humans (Lange). However, everything changed once humans learned to manipulate gene expression by only allowing less hostile breeds to reproduce. Although this method of changing behavioral gene expression has much less control on a specific genomic sequence, it still provides us an insight as to how long we’ve been manipulating genes for: approximately 12,000 years (Lange). Subsequent to a more in depth knowledge of DNA, genetic modification became much more efficient and less time consuming.
In the 1960s, new plant varieties were created by radiation therapy. Some of those plants are even used in everyday products today (Broad). As our knowledge of gene editing enhanced, more efficient techniques became available. Many available methods require the use of gene-editing nuclease, proteins that allow genes to be edited. Zinc finger nuclease, an artificial enzyme, would be one example (Baker). By using these methods, scientists can alter the genomic sequence by cutting out a specific gene and substituting in a different one. However, the outcome of getting the exact change isn’t always guaranteed and sometimes artificial nucleases can be hard to make (Baker). Nonetheless, there’s…
