The expressed sequences in processed RNA are called

Options

A. HnRNA
B. Snurps
C. Sense strands
D. Exons

Answer

To solve the question about the expressed sequences in processed RNA, we can break it down into the following steps:

### Step 1: Understand the Types of RNA
- RNA can be classified into different types based on its processing and function. The main types include heteronuclear RNA (hnRNA), small nuclear RNA (snRNA), and messenger RNA (mRNA).

### Step 2: Define Processed RNA
- Processed RNA refers to RNA that has undergone splicing, where introns (non-coding regions) are removed, and exons (coding regions) are retained. This results in mature RNA, which is ready for translation.

### Step 3: Identify the Components of Processed RNA
- In processed RNA, the sequences that are retained after splicing are called exons. These exons are the coding sequences that express the genetic information.

### Step 4: Analyze the Options
- **Heteronuclear RNA (hnRNA)**: This is immature RNA that contains both introns and exons, so it does not represent processed RNA.
- **Small Nuclear RNA (snRNA)**: This RNA is involved in the splicing process but does not represent the expressed sequences in processed RNA.
- **SENSE strand**: This typically refers to the coding strand of DNA or mRNA but does not specifically denote processed RNA.
- **Exons**: These are the expressed sequences in processed RNA, as they are the parts that remain after introns are removed.

### Step 5: Conclusion
- Based on the analysis, the correct answer to the question is **exons**, as they are the expressed sequences found in processed RNA.

### Final Answer:
The expressed sequences in processed RNA are called **exons**.
