Summary Introduction
Replication, transcription, and translation are important processes of the central dogma of biology. In translation, the mRNA molecule is translated into a protein sequence (amino acids). The mRNA, tRNA, and ribosome are three important components of translation machinery. Initiation, elongation, and termination are major steps involved in translation. Proteins play important roles in the structure and function of cells.
