In the mid-20th century, biotechnology underwent a transformative phase marked by groundbreaking discoveries that significantly enhanced precision and power. One pivotal milestone was the elucidation of the DNA double helix structure by James Watson and Francis Crick in 1953. This breakthrough laid the foundation for understanding genetic information and paved the way for manipulating living organisms at the molecular level.

Subsequent discoveries, such as the development of recombinant DNA technology in the 1970s, enabled scientists to splice and recombine genes from different sources. This breakthrough marked a turning point in biotechnology, offering unprecedented control over genetic material. Genetic engineering techniques emerged, allowing the insertion of specific genes into organisms, leading to the production of genetically modified organisms (GMOs) with desired traits.

The advent of polymerase chain reaction (PCR) in the 1980s further revolutionized biotechnology by allowing the amplification of DNA segments with remarkable precision. This technique became a cornerstone in various applications, from forensic analysis to the cloning of genes.

In the 21st century, CRISPR-Cas9 technology emerged as a game-changer. This powerful gene-editing tool enables targeted modifications within an organism’s genome, offering unparalleled precision and efficiency. Biotechnologists now have the ability to edit genes with unprecedented accuracy, opening avenues for therapeutic applications, agricultural advancements, and innovative solutions to various challenges.

Overall, the discoveries since the 1950s have empowered biotechnologists to manipulate living organisms with remarkable precision, revolutionizing fields ranging from medicine to agriculture and environmental science.
