DNA that does not code for a protein is called

• A. Coding DNA
• B. Genomic DNA
• C. Mitochondrial DNA
• D. Non-coding DNA

Answer: (D)

Non-coding DNA is the part of DNA that does not contain instructions to build proteins. It still has important roles, such as regulating when and where genes are activated, and it includes regulatory regions like promoters and enhancers, introns, and sequences that produce functional RNA molecules. In contrast, coding DNA is the portion that is transcribed and translated into proteins. Genomic DNA refers to the entire genome, while mitochondrial DNA is a separate genome in the mitochondria that contains some protein-coding genes. So, DNA that does not code for a protein is non-coding DNA.
