The Importance of Mendel's Laws in Modern Genetics-The human genome is like an intricate library that stores vast volumes of information about life. The preservation and passing of gene books to future generations is one of the primary tasks of the human genome. In the late 19th century, not long after the construction of the Library of Congress in the United States, Gregor Mendel, an Austrian teacher and abbot, created an acute observation in the garden of a monastery in Brno. After testing and growing 28,000 plants of peas, Mendel discovered the mathematical model that describes how parents transmit their characteristics to their offspring. This discovery laid the foundation for modern genetics, although we can imagine that Mendel at the time did not even know what constituted the genetic element. About a century later, the work of Francis Crick and James Watson led to the discovery of DNA as a genetic element. code carrier.1 Our genetic composition comprises 3 billion base pairs of DNA molecules, and variations in DNA sequences lead to the diversity and individual uniqueness of life on earth. However, within this vast library of genetic codes, errors will inevitably occur, such as a lost book, causing disease or increased vulnerability to harmful insults. Unfortunately, some genetic defects can be passed on and affect future generations. Completed in 2003, the Human Genome Project is an extraordinary international scientific collaboration to decipher the human genetic code. Decoding the human DNA sequence provides us with a sketch of the entire information of the human genome. Today, scientists can determine the complete DNA sequences of 25,000 human genes and access this information with a simple 30-second search. By using this genetic reference, we will advance our knowledge... middle of paper ...over more than a hundred years ago it still helps doctors understand how the gene is passed from shelf to shelf or from generation to generation. It also helps scientists focus on faulty genes. Similar to the Dewey decimal system, Mendel's Laws accurately predict an inheritance pattern of a disease or genetic trait even in the days of the electronic library.Reference1.
