suon 2015 You have sequenced the genome of the bacterium Salmonella typhimurium, and you are using BLAST analysis to identify similarities within the S. typhimurium genome to known proteins. You find a protein that is 100% identical in the bacterium Escherichia coli. When you compare nucleotide sequences of the Scyphimurium and E. coli genes, you find that their nucleotide sequences are only 87% identical. How might the protein sequence be 100% identical, whereas the nucleotide sequence is only 87% identical? Because protein sequencing is more error-prone, the protein sequence was falsely found to be 100% identical. Because nucleotide sequencing is more error prone, the nucleotide sequence was falsely found to be 87% identical. Because the triplet code is de_enerate, changes in the DNA nucleotide sequence can occur without changing the protein that it encodes What is the advantage of using an amino acid- versus a nucleotide-similarity search whon identifying related genes? What is the advantage of using an amino acid- versus a nucleotide-similarity search when identifying related genes? O The similar rate of change in protein and nucleotide sequences means that they are both equally useful for identifying related genes. O The slower rate of change in amino acid sequence leads to greater protein sequence conservation compared to the nucleotide sequence. The slower rate of change in nucleotide sequence leads to greater DNA sequence conservation compared to the amino acid sequence irits Antroducho a Gang Macao
