Conclude why beadle and tatum's "one gene, one enzyme" hypothesis has been modified since they presented it in the 1940s.

"One gene, one enzyme" hypothesis says that one gene encodes for one protein which performs a specific function in the living organisms. This study, published in 1941, was one of the most influential studies of the age and for that, Beadle and Tatus also received Nobel Prize.

However, in recent years, it has been well studied that many enzymes are encoded by more than one gene (or cluster of genes). There are some enzymes that are produced by a single gene; nevertheless, it has been concluded that the hypothesis is not completely true. But it is also important to say that this study set the baseline for the study of many biochemical processes in living organisms.

the fossil record provides evidence of a common ancestor to many species.

picture a world where computers are building made-to-order personalized robotic arms and synthetic organs, drones are circulating above mars! due to the rapid growth of technology, the future has never been more unpredictable, and it presents a huge challenge in education: we are teaching students how to work in a future that we have never been unsure of. it is widely predicted that in eight years’ time, there will be more jobs in the fields of science, mathematics, technology and engineering than in any other discipline. and, as the technology continues to develop, it will soon become clear that addressing social problems will involve more innovative thinking, and analytical and technical knowledge than ever before. undeniably, there are no subjects that encourage innovative and creative thinking, deep thought, problem solving and independence more than the stem subjects. while it is widely commented on that there is a need to reimagine the ways stem subjects are taught in schools by embracing a more interactive and innovative approach to appeal to more students, it should come as no surprise that some of the most reputable educational organizations in the world are already implementing changes to embrace stem. harvard, for example, announced in 2014 that they were increasing their computer science faculty by over 50% and has since introduced computer science as a core subject for all freshmen. the urgency of supporting stem subjects at a young age is becoming more relevant than ever, as adopting a keen interest in the curricula needs to happen early. however, beyond the age issue is one of gender.
