Boivin's pioneering insight would lay the foundation for the understanding of the central dogma of molecular biology, highlighting the flow of genetic information from DNA to RNA to proteins.^[7]	France
1950 (March 1)		Hypothesis	Jeener and Szafarz of the University of Brussels first hypothesize that RNA is synthesized in the cell nucleus and then transferred into the cytoplasm, where it was aggregating with other molecules.^[11]^[12] "The first suggestion that small RNA molecules move from the nucleus to the cytoplasm and associate with ribosomes where they drive protein synthesis was made by Raymond Jeener, in 1950."^[7]	Belgium
1952 (September 1)		Hypothesis	American biochemist Alexander Dounce, of Rochester Medical School, proposes a biochemical model of how protein synthesis occurs on an RNA molecule, not on DNA.^[13] Although the model is wrong, Dounce hypothesises that “the specific arrangement of amino acid residues in a given peptide chain is derived from the specific arrangement of nucleotide residues in a corresponding specific nucleic acid molecule”.^[7]	United States
1952–1954		Discovery	French biochemist Jacques Monod's research team and later American biochemist Arthur Pardee conduct experiments that reveal an interesting connection between RNA synthesis and protein synthesis in mutant bacteria. Their findings show that the production of β-galactosidase, an enzyme, was dependent on the presence of a specific RNA nucleotide called uracil. This discovery suggests that RNA synthesis plays a vital role in the process of protein synthesis. The interpretation shared by Crick and the researchers is that the presence of uracil indicates turnover of RNA molecules in the cytoplasm, implying that some RNA molecules undergo degradation and replacement.^[14]^[15]^[7]
1953		Discovery	James Watson and Francis Crick propose the model of the DNA double helix. After this, a new question would arise in the scientific community: how is information encoded by the DNA and how is it translated?^[5] The mRNA molecule would be originally discovered as a result of scientists' search to understand the molecular mechanism by which DNA directs the formation of proteins within a cell, a search that would begin as soon as DNA was cracked by Watson and Crick.^[2]	United Kingdom
1953		Discovery	Al Hershey and his research team demonstrate that following phage infection, bacteria exhibits a significant increase in the production of a specific type of RNA, which is synthesized at a high rate but also degraded quickly.

This pivotal observation marks a significant turning point in molecular biology, as it reveals the concept of gene expression through the production of a messenger molecule^[17]^[7]^[18]	France (Pasteur Institute)
1958		Nomenclature	RNA-rich microsomal particles are baptised "ribosomes", during informal discussions at a conference. This term is coined to describe these cellular structures, which play a crucial role in protein synthesis. Ribosomes are composed of ribosomal RNA (rRNA) and proteins, and they function as the sites where mRNA is translated into proteins.

They build upon the previous work of Volkin and Astrachan and identify two distinct forms of RNA: one present in the ribosomal fraction and the other in soluble RNA. The researchers propose two possible interpretations for the soluble RNA fraction. It could be a precursor of ribosomal RNA or its breakdown product, or it might be involved in the amino acid acceptance process similar to Crick's adaptor molecule concept. Their findings shed further light on the intricate mechanisms of RNA function and its role in protein synthesis. ^[21]^[7]
1960 (December)		Publication	American scientists Sol Spiegelman and Benjamin Hall publish an article showing that in enterobacteria phage T2, DNA and transitory RNA show sequence complementarity and would hybridize.^[7]^[22] The invention of DNA-RNA hybridization by Hall and Spiegelman would have a powerful impact on the theory and discourse of molecular biology.^[23]	United States

At this time, clinical trials currently evaluate mRNA-based vaccines for various types of cancer, including colorectal cancer, prostate cancer, triple-negative breast cancer, bladder cancer, pancreatic cancer, esophageal squamous carcinoma, gastric adenocarcinoma, melanoma, and non-small cell lung carcinoma.<ref name="The DNA Unive"/><ref>{{cite journal |last1=Miao |first1=Zhen |last2=Balzer |first2=Michael S. |last3=Ma |first3=Ziyuan |last4=Liu |first4=Hongbo |last5=Wu |first5=Junnan |last6=Shrestha |first6=Rojesh |last7=Aranyi |first7=Tamas |last8=Kwan |first8=Amy |last9=Kondo |first9=Ayano |last10=Pontoglio |first10=Marco |last11=Kim |first11=Junhyong |last12=Li |first12=Mingyao |last13=Kaestner |first13=Klaus H. |last14=Susztak |first14=Katalin |title=Single cell regulatory landscape of the mouse kidney highlights cellular differentiation programs and disease targets |journal=Nature Communications |date=15 April 2021 |volume=12 |issue=1 |pages=2277 |doi=10.1038/s41467-021-22266-1 |url=https://www.nature.com/articles/s41467-021-22266-1 |language=en |issn=2041-1723}}</ref> ||

+| 2022 (December 29) || {{w|Melanoma}} || Therapeutic development || A study on {{w|melanoma}} treatment unveils promising results with personalized mRNA vaccines combined with the immunotherapy drug {{w|pembrolizumab}}. In the KEYNOTE/mRNA trial, the combination therapy significantly reduces the risk of recurrence or death by 44% compared to {{w|pembrolizumab}} alone in stage III/IV melanoma patients post-surgery. Although there were slightly more adverse events with the combined therapy, experts hail this advancement as a significant step in melanoma treatment. Personalized mRNA vaccines train the immune system to recognize cancer proteins, potentially revolutionizing cancer therapy. This development, reminiscent of the penicillin moment, indicates a promising future for mRNA vaccines in treating various cancers.<ref>{{cite web |title=Breakthrough in mRNA vaccines for melanoma |url=https://www1.racgp.org.au/newsgp/clinical/breakthrough-in-mrna-vaccines-for-melanoma |website=racgp.org.au |access-date=27 May 2024}}</ref>

+| 2023 (March 17) || {{w|COVID-19}} || || A systematic review examines cardiovascular complications linked to mRNA COVID-19 vaccines (Pfizer-BioNTech's BNT162b2 and Moderna's mRNA-1273). Analyzing data from 81 studies, it identifies 17,636 cases of cardiovascular events, primarily thrombosis, stroke, myocarditis, and myocardial infarction, with 284 deaths reported. Thrombosis was most frequent, especially with Pfizer's vaccine. Myocarditis cases were notably higher among younger males post-Pfizer vaccination. The review suggests that immune responses to mRNA may trigger these effects, especially in genetically predisposed individuals. Findings highlight the need for further studies to clarify vaccine-related cardiovascular risks, focusing on long-term outcomes and event severity across vaccine types.<ref>{{cite journal |title=Adverse Events Following COVID‐19 mRNA Vaccines: A Systematic Review of Cardiovascular Complication, Thrombosis, and Thrombocytopenia |author=Farah Yasmin, Hala Najeeb, Unaiza Naeem, Abdul Moeed, Abdul Raafe Atif, Muhammad Sohaib Asghar, Nayef Nimri, Maryam Saleem, Dhrubajyoti Bandyopadhyay, Chayakrit Krittanawong, Mohammed Mahmmoud Fadelallah Eljack, Muhammad Junaid Tahir, Fahad Waqar |journal=PMC |volume=10022421 |pmid=36988252 |pmcid=PMC10022421 |url=https://pmc.ncbi.nlm.nih.gov/articles/PMC10022421/ |accessdate=31 October 2024}}</ref>

+| 2023 (October 2) || {{w|COVID-19}} || Recognition || The {{w|Nobel Prize in Physiology or Medicine}} is jointly awarded to {{w|Katalin Karikó}} and {{w|Drew Weissman}} for their discoveries in [[w:Nucleoside-modified messenger RNA|nucleoside base modifications]], which paved the way for the development of highly effective mRNA vaccines against {{w|COVID-19}}. Their research revolutionized our understanding of mRNA interaction with the {{w|immune system}}, facilitating the rapid development of vaccines during the pandemic. Before the pandemic, vaccines relied on whole viruses, viral components, or vector systems, requiring large-scale cell culture. Karikó and Weissman's work on mRNA technology overcame previous obstacles, offering a promising avenue for vaccine development independent of cell culture. Their breakthrough, published in 2005, anticipated the mRNA vaccine revolution witnessed during the COVID-19 pandemic.<ref>{{cite web |title=The Nobel Prize in Physiology or Medicine 2023 |url=https://www.nobelprize.org/prizes/medicine/2023/press-release/ |website=NobelPrize.org |access-date=27 May 2024}}</ref>
