1. The average of the DNA code is approximately 98% for all primates.
2. Each gene that codes for a protein in humans has a similar version in chimpanzees.
3. The amino acid sequence of hemoglobin is identical in humans and chimpanzees.
4. There are no more than 100 differences in the entire genome between humans and chimpanzees.
5. For any one codon, there can be only one amino acid; however, for any one amino acid, there can be multiple codons.
6. A single base substitution mutation can result in a different amino acid being incorporated into a protein.
7. Some mutations are silent because they do not change the amino acid sequence of the protein.
8. Mutations that occur in non-coding regions or that result in synonymous codons are often neutral.
9. Mutations can be beneficial, harmful, or neutral depending on their effect on the organism's fitness.
10. Natural selection acts on the phenotypic effects of mutations, favoring those that increase survival and reproduction.
