These discoveries did not happen suddenly. They took more than 150 years of observation, experiments, mistakes, and corrections.</p> <p>In 1869, Friedrich Miescher discovered a substance called nuclein, which we now know as DNA. Later, Mendel explained inheritance using “factors,” even though genes were not yet known. Walter Sutton connected these factors with chromosomes, and Johannsen gave the term gene. William Bateson later introduced the word genetics.</p>
