Genetic Code Consistency
The genetic code is remarkably conserved across all forms of life, from bacteria to plants, providing strong evidence for a common ancestor. While minor variations exist, particularly in human mitochondrial genes, the overall consistency suggests that different origins of life are unlikely. Understanding the relationship between the two strands of DNA reveals that, despite their complementary nature, they can code for different proteins based on the order of nucleotides.In this clip
