Figure 263

question 35

Multiple Choice

Figure 26.3. Morphologically, species A is very similar to four other species, B-E. Yet the nucleotide sequence deep within an intron in a gene shared by all five of these eukaryotic species is quite different in species A compared to that of the other four species when we study the nucleotides present at each position.
-If the sequence of species A in Figure 26.3 differs from that of the other four species due to simple misalignment, then what should the computer software find when it compares the sequence of species A to those of the other four species?

• A) The nucleotide at position 1 should be different in species A, but the same in species B-E.
• B) The nucleotide sequence of species A should have long sequences that are nearly identical to those of the other species, but offset in terms of position number.
• C) The sequences of species B-E, though different from that of species A, should be identical to each other, without exception.
• D) If the software compares the amino acid sequence of the actual protein product rather than the nucleotide sequence, then the amino acid sequences of species B-E should be similar to each other, but very different from that of species A.
• E) Computer software is useless in determining sequences of introns; it can only be used with exons.
