The regions of DNA or RNA that are eventually expressed and translated into amino acid sequences are known as **exons**.

### Explanation:
1. **Exons**: These are the coding sequences within a gene that are retained after RNA splicing. During the process of transcription, a segment of DNA is copied into messenger RNA (mRNA), which may contain both exons and introns. However, during RNA processing, introns (non-coding sequences) are removed, and the exons are joined together to form the mature mRNA. The sequence of the mature mRNA then dictates the order of amino acids in the protein during translation.

2. **Introns**: In contrast, introns are the non-coding sequences of DNA or RNA that are present within a gene. They are transcribed into pre-mRNA but are spliced out before translation occurs. Introns do not contribute to the final amino acid sequence of proteins.

Therefore, when referring to those regions that will be expressed and translated, the correct answer is **exons**.
