The terms DNA and genes are often used to mean the same thing. In reality, however, they stand for very different things. Therefore, next time you want to blame your physical appearance on your mother and don’t know whether to berate your DNA and genes, take a look at the following differences.
DNA stands for deoxyribonucleic acid. It is the chain of ‘links’ that control how different cells in our body functions. Each link is known as a nucleotide. Basically, DNA has two copies of 23 chromosomes each. One copy comes from the father and the other one comes from the mother. DNA carries genetic information. In other words, they are parts that decide what people inherit from their parents. This makes genes a subset of the DNA.
Genes define the fundamental characteristics we inherit from our parents. They are DNA parts that determine how the cells function and live. They decide how protein carries on the process of reproducing and building in our body. Genes determine how living things develop and how they pass on their genetic traits to their offspring. Let imagine a human body is a book that has only DNA. In that case, genes would be chapters that contain instructions on how to assist in cell production and formation of proteins.
