The importance of Mendel's laws in modern genetics-The human genome is like a complex library that stores vast volumes of information about life. Preserving and transmitting books of genetics to future generations is one of the main tasks of the human genome. In the late 19th century, shortly after the Library of Congress was built in the United States, Gregor Mendel, an Austrian professor and abbot, made a thorough observation in the garden of a monastery in Brno. After testing and selecting 28,000 pea plants, Mendel discovered the mathematical pattern of describing how parents pass their traits to their offspring. This discovery laid the foundation for modern genetics, although we can imagine that Mendel didn't even know what constituted the cornerstone of genetics at the time. 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 makeup includes 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, like a misplaced book, leading to illness or increased vulnerability to harmful insults. Unfortunately, some genetic defects can be passed down and affect future generations. Completed in 2003, the Human Genome Project is an extraordinary international scientific collaboration aimed at deciphering the human genetic code. Decoding the human DNA sequence provides us with insight into the full 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 covered more than a hundred years ago still helps doctors understand how the gene is passed from shelf to shelf or from generation to generation. Additionally, it helps scientists focus on faulty genes. Analogous to the Dewey Decimal System, Mendel's laws accurately predict the inheritance pattern of a disease or genetic trait, even in the era of the electronic library.Reference1.
