RNA-based evolution
RNA-based evolution refers to the process by which RNA (ribonucleic acid) molecules change and evolve over time. RNA is a type of molecule that is important in the transfer of genetic information from DNA to proteins.
Let's pretend you have a recipe for making cookies. This recipe is like the instructions for building a house, but for making cookies. In the same way, our bodies have instructions for building different parts of our body, and these instructions are stored in DNA.
DNA is like a big book of recipes, and each recipe (called a gene) makes something different. RNA is like the messenger that brings the recipe to the kitchen. It takes the recipe (gene) from the DNA book and carries it to a part of the cell called the ribosome, which makes the protein that the recipe instructs.
But sometimes, something can change in the RNA message or recipe, kind of like if someone changed the recipe for cookies by adding more sugar or changing the amount of flour. These changes can be beneficial, harmful or neutral.
If the change is beneficial, it can help an organism survive and reproduce better than others, so over time, the new recipe becomes more common in the population. This is called evolution.
So if you think of the book of recipes as the DNA and the RNA message as the recipe itself, RNA-based evolution is the process of changing and modifying the recipe to produce different and potentially more efficient proteins, which may have offered a significant advantage in survival in the ancestral organism, leading to both diversity and adaptation.
