Human cells turn genetic instructions into proteins with great precision. Critical for the translation of this information are transfer RNAs, or tRNAs, small molecules that read the genetic code three letters at a time and bring the matching building blocks of proteins, the amino

Human cells turn genetic instructions into proteins with great precision. Critical for the translation of this information are transfer RNAs, or tRNAs, small molecules that read the genetic code three letters at a time and bring the matching building blocks of proteins, the amino acids, to the cell's protein-making machinery, the ribosome.

400,000-year-old teeth reveal a stunning twist in human evolution

A groundbreaking discovery is rewriting the story of human evolution, revealing that an ancient human species once thought to be an evolutionary dead end may have left genetic traces in people alive today. By extracting proteins from 400,000-year-old Homo erectus teeth discovered
