The Discovery Of Trans Covenants By Barbara Mcclintock

English actress Julie Andrews once stated, ”Perseverance is failing nineteen times and succeeding the twentieth.” People decide to give up on ideas, when all it could take to succeed is one last try. Barbara McClintock was born in Hartford, Connecticut, on June 16, 1902. She went to Cornell University and died at age ninety in 1992. She never married and was the first woman to earn an unshared Nobel Prize in the field of genetics and medicine. (“Barbara McClintock,” N.D.) McClintock discovered trans Covenants, altering the study of genetics by providing people with a reason behind so-called “Junk DNA,” and showing society how evolution functions. Barbara McClintock discovered trans Covenants by studying maize and its different coloured kernels.

(“Barbara McClintock,” N.D.) Using her skills, she discovered that pieces of genes can move through your chromosome, earning it the name “Jumping Genes.”The final position of these genes would determine the offspring's traits. (“McClintock, Barbara,” N.D.) Because her work was so ahead of her time, people ignored or disagreed with her research, believing this only applied to maize chromosomes. Barbara McClintock, N.D., changed genetics by giving people a reason behind “junk DNA.”Before McClintock showed her findings, people had thought that trans Covenants were junk DNA, repeating pieces of already existing DNA. She proved they are extremely important, as they can be used to introduce a piece of foreign DNA to the genome. Transposon movement can also result in mutations, alter gene expression, induce chromosome rearrangements and, due to increase in copy numbers, enlarge genome sizes. This is the reason behind many mutations and diseases. (Muoz-López, 2018) Trans Covenants contributed a lot to our world, as it showed society how evolution
