Gene and DNA are two terminologies used primarily in Genetics, basically, a gene is a section of DNA and DNA (Deoxyribonucleic Acid) is a molecule which carries the genetic instructions or the hereditary materials.
DNA is found inside the nucleus of a cell, where it forms the chromosomes. The chromosomes have proteins called histones that bind to DNA. DNA consists of two strands that twist into the shape of a spiral ladder called a helix. It is made up of four building blocks called nucleotides, namely , Adenine (A), Thymine (T), Guanine (G), and Cytosine (C). The nucleotides get attached to each other (A with T, and G with C) to form chemical bonds called base pairs, which connect the two DNA strands.
Genes, made up of sequences of DNA, are arranged one after another, at specific locations on chromosomes in the nucleus of cells. They contain the information for making specific proteins that lead to the expression of a particular physical characteristic or trait, such as hair color or eye color, or to a particular function in a cell. The genes are responsible for our unique physical characteristics.

Genes are segments of DNA that contain the instructions for building and maintaining an organism. They carry the genetic information that determines the characteristics and functions of an organism, including traits like eye color, height, and the ability to metabolize certain nutrients. Genes are passed from parents to offspring and are responsible for hereditary traits.
DNA (Deoxyribonucleic Acid) is the molecule that carries genetic information in all living organisms. It consists of two long chains of nucleotides twisted into a double helix. DNA is composed of four types of nucleotides, represented by the letters A (adenine), T (thymine), C (cytosine), and G (guanine). The sequence of these nucleotides encodes the genetic information. DNA is found in the nucleus of eukaryotic cells and in the cytoplasm of prokaryotic cells.
What Happens to DNA/Genes When We Eat Plants and Animals?
When we consume plants and animals, we ingest their cells, which contain DNA and genes. Here’s what happens to this DNA:
1. Digestion and Breakdown:
– The DNA in the food we eat is broken down during the digestive process. Enzymes in the stomach and intestines, such as nucleases, break down the DNA into smaller components called nucleotides and then further into nucleosides and nitrogenous bases.
– These smaller components are absorbed by the cells lining the intestines and can be used as building blocks for various biological molecules, including our own DNA and RNA.
2. Absorption and Utilization:
– The nucleotides and other breakdown products can be absorbed into the bloodstream and transported to various cells in the body, where they may be used in the synthesis of new DNA, RNA, and other cellular components.
3. No Integration into Our DNA:
– The DNA and genes from the food we consume are not integrated into our genome. Our body’s cells maintain their own DNA, which is inherited from our parents and remains largely unchanged throughout our lives (except for mutations or alterations due to environmental factors or disease).
4. No Effect on Genetic Traits:
– Consuming DNA from food does not affect our genetic traits or influence the genes that we pass on to our offspring. Our genetic information is stored in the DNA of our cells and is not altered by the DNA we ingest.
Conclusion
In summary, when we eat plants and animals, the DNA they contain is broken down into basic components during digestion and used by our bodies for various biological functions. However, this ingested DNA does not become part of our own genetic material or influence our genetic traits. Our genome remains separate and intact, preserving the genetic information that defines us as individuals.
