The picture

You're the geneticist on a team that's uncovered a Wooly Mammoth in the ice and you want to study the function of its hemoglobin protein. First, you need to PCR amplify the gene to be able to Sanger sequence it. What reference genome do you use to design primers? O The human genome because it's the best O The bat genome because bats are cool O The elephant genome because it likely has the most sequence similarity given evolutionary distance O The E. coli genome because they're such a great model organism O The yeast genome because they're small and they're a eukaryote

A scientist investigating the genome of two related individuals observes a difference of a few nucleotides in one individual compared to the other. The nucleotide differences are in a region of noncoding DNA on chromosome 1. Would these differences be considered a mutation? Why or why not? Yes, the difference in nucleotide sequences between the individuals is a mutation because it will affect the phenotype of the two individuals. Yes, any heritable variation in the nucleotide sequence is considered a mutation, even if that variation is in a noncoding region of DNA. Not enough information was provided to determine if this nucleotide difference is a mutation because the effect on phenotype is unknown. No, the change in nucleotide sequence doesn't appear in a coding region of the DNA and so can't be a mutation.
