Expert Answer:

Metameric segmentation refers to the repetition of identical segments along the length of an organism’s body. E.g. as in an earthworm. So the body is divided in a linear fashion into a succession of similar or identical segments.
In simple words, a proto oncogene is a normal gene that has the potential to become an oncogene. They are normal genes that are found in normal eukaryotic cells and concerned with various aspects of cell division. If amplified, mutated, rearranged, or picked up by a retrovirus, they may give rise to oncogenes that can cause cancer.
