Genes essential for coding proteins in human genome are nearly

Options

A. `2%`
B. `28%`
C. `30%`
D. `1.2%`

Answer

To solve the question regarding the percentage of genes essential for coding proteins in the human genome, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Human Genome**: The human genome is the complete set of genetic information (nucleic acids) contained within human chromosomes. It includes all the genes and non-coding regions.

2. **Define Genes**: Genes are segments of DNA that contain the instructions for making proteins. These proteins are essential for various functions in the body.

3. **Identify Protein-Coding Genes**: In the human genome, only a small fraction of the total DNA actually codes for proteins. This is important to note as it highlights the difference between coding and non-coding regions of the genome.

4. **Percentage of Protein-Coding Genes**: Research indicates that less than 2% of the human genome consists of genes that code for proteins. This means that the vast majority of the genome does not code for proteins but may have other regulatory or structural functions.

5. **Conclusion**: Therefore, the answer to the question is that genes essential for coding proteins in the human genome are nearly 2%.

### Final Answer:
The genes essential for coding proteins in the human genome are nearly 2%.
