Genetic information is passed from one generation to the next from "summary" of El gen / The Gene: An Intimate History by Siddhartha Mukherjee
Genetic information, the code that determines our physical traits, is a remarkable entity that is transmitted from one generation to the next. This information is stored in our DNA, a molecule that carries the instructions for building and maintaining our bodies. The process by which genetic information is passed down is known as heredity, and it has been a subject of fascination and study for centuries. DNA, the molecule that contains our genetic information, is composed of four chemical building blocks called nucleotides. These nucleotides are arranged in a specific sequence that determines our unique characteristics. When an organism reproduces, it passes on a copy of its DNA to its offspring, ensuring that the genetic information is transmitted from one generation to the next. The transmission of genetic information is a crucial aspect of evolution, as it allows for the accumulation of changes over time. Through the process of natural selection, organisms with beneficial genetic variations are more likely to survive and reproduce, passing on those advantageous traits to future generations. This gradual accumulation of genetic changes is what drives the diversity of life on Earth. While the transmission of genetic information is a fundamental process, it is not without its complexities. Genetic information can be influenced by a variety of factors, including environmental conditions, mutations, and genetic recombination. These factors can introduce variability into the genetic code, leading to differences in traits among individuals within a population.- The concept of genetic information being passed from one generation to the next is a fundamental aspect of biology. It is through this process that the blueprint for life is preserved and perpetuated, allowing for the continuation of species and the diversity of life on Earth.
