The given mutation of the DNA segment ctc ctc ttc to ctc ctt ttc is a known type of mutation in the gene for beta-globin. The translated protein remains unchanged because both the CTT and CTC codons code for the amino acid glutamic acid.
This figure illustrates 3 hypotheses of how a cancer stem cell may arise: (1) A stem cell undergoes a mutation, (2) A progenitor cell undergoes two or more mutations, or (3) A fully differentiated cell undergoes several mutations that drive it back to a stem-like state.
