Historian hassuggested that German geneticist generated similar resultsbefore Beadle and Tatum's celebrated 1941 work. Working on thealgae , Moewus published, inthe 1930s, results that showed that different genes wereresponsible for different enzymatic reactions in the production ofhormones that controlled the organism's reproduction. However,these results were challenged by others who found the data 'toogood to be true' statistically, and the results could not bereplicated.

ATTENTION - When talking about RNA and proteins as enzymes
-Genes act as the production of enzymes, each gene producing a single enzyme.
- One gene-One enzyme hypothesis: BUT - One Gene-One Polypeptide - One gene-one polypeptide hypothesis was modified: one gene can create multiple polypeptide chains.

Phakomatoses. There are a group of disorders that affect both the skin and the central nervous system. These disorders, called neurocutaneous disorders or , may result in epilepsy or intellectual disability, depending on the extent to which the brain is affected. While a genetic basis for some neurocutaneous disorders including (TSC) and is known, the etiology of other neurocutaneous diseases remains unknown. Now, a in the New England Journal of Medicine reports on the genetic alterations underlying one of the most common neurocutaneous disorders, .
The codons are read in the 5'->3' direction along the mRNA.
Each codon specifies which one of the 20 amino acids will be incorporated at the corresponding position along a polypeptide.

By the early 1950s, advances in biochemical genetics—spurred inpart by the original hypothesis—made the one gene-one enzymehypothesis seem very unlikely (at least in its original form).Beginning in 1957, and others showed through thatgenetic variations in proteins (such as sickle cell hemoglobin)could be limited to differences in just a single polypeptide chainin a , leading to a "onegene-one polypeptide" hypothesis instead.According to geneticist Rowland H. Davis, "By 1958 – indeed, evenby 1948 – one gene, one enzyme was no longer a hypothesis to beresolutely defended; it was simply the name of a researchprogram."
In their first Neurospora paper, published in theNovember 15, 1941, edition of the , Beadle and Tatumnoted that it was "entirely tenable to suppose that these geneswhich are themselves a part of the system, control or regulatespecific reactions in the system either by acting directly asenzymes or by determining the specificities of enzymes", an ideathat had been suggested, though with limited experimental support,as early as 1917; they offered new evidence to support that view,and outlined a research program that would enable it to be exploredmore fully.By 1945, Beadle, Tatum and others, working with Neurosporaand other model organisms such as , had producedconsiderable experimental evidence that each step in a metabolicpathway is controlled by a single gene. In a 1945 review, Beadlesuggested that "the gene can be visualized as directing the finalconfiguration of a protein molecule and thus determining itsspecificity." He also argued that "for reasons of economy in theevolutionary process, one might expect that with few exceptions thefinal specificity of a particular enzyme would be imposed by onlyone gene." At the time, genes were widely thought to consist of or (although the and related work was beginning to cast doubt on thatidea). However, the proposed connection between a single gene and asingle protein enzyme outlived the protein theory of genestructure. In a 1948 paper, Norman Horowitz named the concept the"one gene-one enzyme hypothesis".

Atherosclerosis is one of the most common causes of mortality in Western countries(). Therefore, it still remains as a challenging disorder and needs efficient treatment strategies. Thus, taking advantage of gene therapy and cell therapy approaches, which have been emphasized in many different malignancies and diseases(-), can be helpful in the treatment or management of atherosclerosis as promising therapeutic methods.

a team of scientists went looking for yellow fever in the jungles that line the northwestern edge of Lake Victoria. What they found instead, in the blood of a rhesus monkey, was a new virus, one they named for the area’s dense vegetation: Uganda’s Zika Forest. Within a few years, was showing up in humans, causing a pink rash and mild flu-like symptoms. And for the next six decades, as it spread eastward on the wings of the Aedes aegypti mosquito, its symptoms stayed the same.

In in Science, researchers from some of China’s largest academic institutions report that a single genetic change, which likely happened around May of 2013, swapped one amino acid on one of the virus’s three structural proteins—a tiny tweak with catastrophic effects. The research highlights the importance of a global genetic surveillance system for emerging pathogens, and opens the door to developing better predictive tests for expectant mothers.
