Explanation:
Answer:
e. whether or not the impulse begins in the CNS
Explanation:
Nerve impulse is action potential movement through the axon. Nerve impulse propagation has its velocity (speed at which nerve impulse travels down the axon) which depends on many factors. For example, myelination increases the conduction velocity. Also, the larger the diameter of an axon, the higher the velocity is. Nodes of Ranvier present on the axons, and myelin sheath between the nodes act as a good electrical insulator which also increases the velocity.
DNA fingerprints, such as those first used by Alec Jeffries, reveal variations in the locations of restriction enzyme recognition sites between different individuals.
DNA fingerprinting is a techniques that can identify the proportion of similarity or dissimilarity between two samples of gene. It is extensively used in forensics, to find the maternal and paternal relations. The principle of fingerprinting lies in recognizing the unique bands of DNA that are then matched with the other sample.
Restriction enzymes are also known by the name molecular scissors. These are endonucleases that cut the bases of DNA at the inside at specific locations only.
