Scientists Identified Several DNA Regions That Potentially Held the Sequence

question 15

Multiple Choice

Scientists identified several DNA regions that potentially held the sequence that contributed to the different beak shapes in Darwin's finches. What was the next step used to determine which region might be responsible?

• A) Sequences were compared to those from other animals to see if they contained genes that might be involved in beak development
• B) Sequences were compared to those of related finches from the mainland to see if beak size was similar
• C) Protein production was compared in the different bird species to see if they produced different beak proteins.
• D) RNA transcription was examined in the different bird species to identify the genes
