Speed and Distances mRNAs Travel On (VIDEO) Center for Genomic Regulation This video is under embargo. Please login to access this video. Caption mRNAs travel across relatively vast distances. Here they make their way across a network of microtubule roads 40 micrometers long. A typical neuron is ten times this length. Automated tracking of transported RNAs (lower panel) reveals the transport velocity and number of mRNAs transported in the same package.
