Use the codon table to determine whether or not this mutation will cause a change in the phenotype of the organism.

B). No, even the DNA sequence changed, the sequence still codes for the same amino acid, so no change in phenotype will occur.

Explanation: Codons are triplets of nucleotides that code for specific amino acids. In the example shown above, the original DNA sequence ACG is mutated to ACA. The mRNA sequences for the original DNA and mutated DNA are UGC and UGU respectively, and from the universal genetic code chart above, both UGC and UGU code for amino acid cysteine. This means that the protein will have the same amino acid sequence, therefore there will be no change in the phenotype of the organism.

a motor homunculus represents a map of brain areas dedicated to motor processing for different anatomical divisions of the body.

homunculus represents the importance of various parts of your body as seen by your brain. as a result, they take up a lot of brain space. although the cortical homunculus is a curiosity, penfield's work in mapping the brain's relationship to the body was invaluable.
