_____ are the nucleotides necessary to make the protein.

Explanation:
The coding segments of a gene that are retained in the mature mRNA and translated into amino acids are exons. Introns are removed during RNA processing, so they don’t contribute to the protein sequence. Promoters are DNA regions that recruit transcription machinery and aren’t part of the transcribed coding sequence, while splice sites help remove introns and don’t themselves encode amino acids. Some exons may include untranslated regions, but the portion that becomes protein comes from exons. So exons are the nucleotides necessary to make the protein.
