Question
**DNA Sequences and Protein Function Analysis** Examine the following two DNA sequences: - **Sequence 1:** ATGCGATGCTAGCAT - **Sequence 2:** ATGCGGATGATAGCAT **Question:** If both of these sequences code for proteins, how might the function of protein 2 differ from the function of protein 1? Use the table below for assistance. **Codon Table Explanation:** The table provided is a standard genetic code chart used to translate mRNA codons into amino acids. It is organized as a matrix: - The rows and columns are labeled with the nucleotides: U, C, A, and G. - By matching the first, second, and third positions of a codon from mRNA, you can find the corresponding amino acid. **Answer Options:** A) Protein 1 and protein 2 will function exactly the same. B) Protein 1 will be shorter than protein 2, so they will not function the same. C) Protein 2 will be shorter than protein 1, so they will not function the same. D) Protein 2 has a different sequence, so it will function differently from protein 1. **Analysis:** - Determine the mRNA sequences and identify the codons. - Translate the sequences into amino acids using the provided table. - Compare the resulting protein structures to determine differences in length and composition, which influence function.
