To determine if the amino acid changed where the mutation took place, we need to compare the original DNA sequence with the mutated DNA sequence and see if there is a change in the mRNA sequence.<br /><br />Original DNA sequence: T A C A G A T T T G C G A C G A C T<br />Mutated DNA sequence: T A C A G A T T T G G A C G A C T<br /><br />Comparing the two DNA sequences, we can see that there is a change in the third nucleotide of the second codon. The original DNA sequence has a 'G' at that position, while the mutated DNA sequence has a 'G' at that position.<br /><br />Now let's compare the mRNA sequences:<br /><br />Original mRNA sequence: AUG AAA CGC UGC UGA<br />Mutated mRNA sequence: AUG UCU AAA CCU GCU<br /><br />We can see that there is a change in the second codon of the mRNA sequence. The original mRNA sequence has 'AAA' at that position, while the mutated mRNA sequence has 'UCU' at that position.<br /><br />To determine if the amino acid changed where the mutation took place, we need to translate the mRNA sequence into amino acids. The genetic code is universal, and each codon corresponds to a specific amino acid.<br /><br />Original mRNA sequence: AUG AAA CGC UGC UGA<br />Amino acid sequence: Met-Lys-Arg-Cys-Stop<br /><br />Mutated mRNA sequence: AUG UCU AAA CCU GCU<br />Amino acid sequence: Met-Ser-Lys-Pro-Ala<br /><br />Comparing the amino acid sequences, we can see that the amino acid at the second position changed from Lysine (Lys) to Serine (Ser).<br /><br />Therefore, the answer to the first question is: Yes, the amino acid changed where the mutation took place.<br /><br />To determine if the entire protein changed, we need to consider the effect of the mutation on the amino acid sequence. In this case, the mutation occurred in the second codon, which resulted in a change in the amino acid at that position. However, the rest of the amino acid sequence remains the same.<br /><br />Therefore, the answer to the second question is: No, the entire protein did not change.<br /><br />Finally, to determine the type of mutation that took place, we need to consider the nature of the change in the DNA sequence. In this case, the change occurred in the third nucleotide of the second codon, which resulted in a change in the mRNA sequence and the amino acid at that position.<br /><br />This type of mutation is called a point mutation, specifically a missense mutation, where a single nucleotide change results in a different amino acid being incorporated into the protein.<br /><br />Therefore, the answer to the third question is: Point mutation (missense mutation).
