The difference between normal and sickle hemoglobin at the DNA, RNA, and protein is that a sickle hemoglobin at the DNA is a result of a point mutation from one base. The RNA in a sickle hemoglobin changes from GAG to GUG, and the protein (amino acid) level changes from GLU to Val). Sickle cell is a genetic disorder, which is produced by a change in the nucleotide progression that codes for a protein. In this example, sickle cell is produced by one single nucleotide being changed for another (so, instead of the DNA being AATTGC, it would be AATAGC).

The correct answer is - he wanted to be sure before considering before the bird as a new type if it really represents new species.
Explanation:

Dr. Wilson seems to be sure before considering the bird that Dr. smith found as the new species. It is because he wants to sure if it's not an unusual example of the pre-described species.
