The expressed sequences in processed RNA are called

Options

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

Answer

To solve the question "The expressed sequences in processed RNA are called," we will analyze the options provided and determine which one correctly identifies the expressed sequences.

### Step-by-Step Solution:

1. **Understanding the Question**: We need to identify what the expressed sequences in processed RNA are called. Processed RNA refers to RNA that has undergone modifications after transcription, such as splicing.

2. **Analyzing the Options**:
- **Option 1: HnRNA (Heterogeneous Nuclear RNA)**:
- HnRNA refers to the large precursor mRNA (pre-mRNA) that is transcribed in the nucleus. It includes both exons and introns and is not fully processed. Therefore, this option is incorrect.

- **Option 2: snRNPs (Small Nuclear Ribonucleoproteins)**:
- snRNPs are complexes that play a role in the splicing of pre-mRNA. They help form the spliceosome but are not the expressed sequences themselves. Thus, this option is also incorrect.

- **Option 3: Sense Strand**:
- The sense strand is the coding strand of DNA that carries the translatable code. It is not directly related to processed RNA, as it refers to DNA rather than RNA. Therefore, this option is incorrect.

- **Option 4: Exons**:
- Exons are the expressed sequences that remain after the splicing process. They are the coding regions of the RNA that are translated into proteins. Since exons are indeed the expressed sequences in processed RNA, this option is correct.

3. **Final Answer**: The expressed sequences in processed RNA are called **Exons**.
