Transcription is when a recipe is copied out of a cookbook into another cookbook, and translation is when the cookbook is read, ingredients are put together, and the cookies are made. Transcription is the copying of a recipe from a cookbook to an index card, and translation is combining the baking ingredients and making chocolate chip cookies. Transcription is when the baking ingredients are combined and chocolate chip cookies are made, and translation is when the recipe from a cookbook is copied to an index card. Transcription is the copying of a recipe from a cookbook to an index card, and translation is rewriting the recipe on an index card into another language. Transcription is the copying of a recipe from a cookbook to an index card, and translation is combining the baking ingredients and saving them to bake at a later time.
