The part of protein coding gene that is translated into protein is called

Options

A. Primary transcript
B. Exons
C. Open reading frames
D. Antisense

Answer

To solve the question "The part of protein coding gene that is translated into protein is called," we can follow these steps:

### Step 1: Understand the Question
The question is asking for the specific term that refers to the segment of a protein-coding gene that is actually translated into a protein.

**Hint:** Focus on the terminology used in genetics related to gene expression and translation.

### Step 2: Analyze the Options
We need to evaluate the provided options one by one to determine which one fits the definition of the translated part of a protein-coding gene.

1. **Primary Transcript**: This is the initial RNA molecule synthesized during transcription. It includes both coding and non-coding regions and is not yet processed into mature mRNA.

**Hint:** Remember that the primary transcript includes introns and exons before splicing.

2. **Exon**: Exons are the coding sequences in the RNA that remain after splicing. They are the parts of the gene that are expressed and ultimately translated into protein.

**Hint:** Exons are the segments that contribute to the final mRNA after introns are removed.

3. **Open Reading Frames (ORFs)**: An open reading frame is a continuous stretch of codons that starts with a start codon and ends with a stop codon. It is the portion of the mRNA that is translated into a protein.

**Hint:** ORFs are crucial for identifying where translation begins and ends in the mRNA.

4. **Antisense**: This refers to the strand of DNA that is complementary to the sense strand, which is used as a template for RNA synthesis. It is not directly involved in the translation process.

**Hint:** Antisense is more about the directionality of DNA strands rather than the actual coding for proteins.

### Step 3: Identify the Correct Answer
From the analysis:
- The **exon** is a part of the gene that is translated into protein, but it is not the complete definition of the translated segment.
- The **open reading frame (ORF)** is specifically the segment that is translated into protein, as it encompasses the codons that will be used during translation.

Thus, the correct answer to the question is **Open Reading Frame (ORF)**.

### Final Answer
The part of the protein coding gene that is translated into protein is called **Open Reading Frame (ORF)**.
