There is no single percent number. At any given moment, depending upon your diet (meats, legumes) and pathogenic interaction (viruses), you may have as little as 0.00003% or as much as 0.02%. That sounds like almost nothing, but is really alot if you consider DNA recombination.
DNA
The codes for proteins are found in the exons of a gene. Exons are the coding regions of a gene that are transcribed into mRNA and translated into proteins. Introns, on the other hand, are non-coding regions that are spliced out during RNA processing and do not contribute to protein synthesis.
DNA contains the instructions to make proteins, and ribosomes are the cellular machinery that reads this information and synthesizes proteins accordingly. Ribosomes use the information encoded in DNA to assemble amino acids in the correct order, forming proteins that carry out various functions in the cell. Thus, DNA provides the genetic blueprint for protein synthesis, and ribosomes are the key players in translating this information into functional proteins.
Approximately 1-2% of the human genome encodes the instructions for building proteins. These protein-coding regions are known as exons, while the remaining non-coding regions are called introns.
DNA sequences are transcribed into messenger RNA (mRNA) during the process of protein synthesis. This mRNA serves as a template for ribosomes to synthesize proteins based on the genetic code encoded in the DNA.

The coding part of DNA is represented by exons. Exons are the segments of DNA that contain the instructions for the synthesis of proteins. They are transcribed into mRNA and eventually translated into proteins.
Approximately 1-2 of DNA is responsible for coding proteins.
Non-coding RNAs (ncRNAs) are a type of RNA molecule that do not encode proteins. They play various regulatory roles in the cell, such as controlling gene expression. In contrast, RNAs that encode proteins are called messenger RNAs (mRNAs) and carry the genetic information needed to produce proteins. The main difference between ncRNAs and protein-coding RNAs is their function - ncRNAs regulate gene expression without producing proteins, while protein-coding RNAs are translated into proteins.
Approximately 1-2% of the human genome encodes the instructions for building proteins. These protein-coding regions are known as exons, while the remaining non-coding regions are called introns.
DNA sequences are transcribed into messenger RNA (mRNA) during the process of protein synthesis. This mRNA serves as a template for ribosomes to synthesize proteins based on the genetic code encoded in the DNA.
The codon AUG is called the start codon in genetic coding because it signals the beginning of protein synthesis in a gene. It initiates the process of translating the genetic information into a protein.

Exons are the parts of DNA that provide the code for proteins. They are the coding regions of genes that are transcribed into messenger RNA and translated into proteins. The exons are separated by introns, which are non-coding regions of DNA.
