One of their progeny is a white-eyed female. Below are several steps involved in the Southern blotting procedure. Blot the DNA from the gel to a filter paper. Separate the DNA by size in an electrical field in an agarose gel. Expose the filter paper to a labeled probe to allow hybridization.
Telomeres shorten slightly after each cell division.
After 30-50 divisions, cells begins to die. In the immune system certain capacity for protection is lost. Many normal somatic cells gain the ability to divide indefinitely. Both A and D are correct. Cause death in homozygotes.
