Question

the information that ultimately encodes the shape and sequence of a protein comes from:
○ dna
○ amino acids
○ carbohydrates
○ mrna
○ a ribosome

Explanation:

The genetic information encoding a protein's sequence (and thus its shape, as sequence determines structure) is stored in DNA. mRNA is a temporary copy of DNA's information used for translation, amino acids are the building blocks of proteins, carbohydrates are energy/storage molecules, and ribosomes are the sites of protein synthesis—none of these are the ultimate source of the encoding information.

Answer:

DNA
