Examples of facilitated diffusion are the passing of K+ ions through a membrane with an aid of a potassium transport protein and the passing of glucose and amino acids with the aid of proteins called permeases. Retinol b... More »

Transcription RNA, or tRNA, carries amino acids to the messenger RNA, or mRNA, as it exits the cell nucleus and contributes them to the building of proteins. Each unit of tRNA carries a specific amino acid, and when the ... More » Science Biology Molecular Biology & DNA
