Where are genes for specific traits or alleles carried?
What will be an ideal response?
Nodes of Ranvier are the spaces between sections of axon enwrapped with myelin. Because myelin creates an insulating layer that prevents ion flow, the progress of the action potential "jumps" from node to node, thus speeding up transmission down the axon.You are studying a gene that, when mutant, causes oligodendrocytes to enwrap shorter sections of axon, so that nodes of Ranvier are more closely spaced. What is the likely effect on nerve impulses?
A. They will travel slower. B. They will decrease in amplitude. C. They will travel laterally across connected axons. D. They will travel faster. E. They will increase in amplitude.
