What Are Genes? – It Might Surprise You
What are genes? They’re nothing more than proteins that code for specific instructions to a cell. The DNA strands in each cell are single-celled, but they’re made up of thousands of proteins that act as connectors. The actual DNA is passed down only from mother to daughter. genes are, in essence, “letters” that can be changed and passed on from generation to generation.
Humans, as we know them today, were developed over hundreds of thousands of years ago from a group of individuals who lived in Africa. During the course of their lives, they reproduced and their descendants are the individuals we call ourselves today. Most of our DNA is passed down unchanged from mother to child. That’s why there’s little chance of us receiving a genetic disease or trait.
Certain traits are determined by other genes. For example, eyes are determined by genetics. If there’s any damage or distortion to the structure of one of the genes controlling the eyes, then it could cause blindness. But eye color doesn’t depend on this one gene.
Genes also affect the various organs and systems of the body. In the liver, genes determine how cells grow and divide. When a disease or injury occurs, cells may divide too quickly or not at all. It’s possible that some cells die and others remain to repair the injury or to heal it. Some cells have the capability of repairing themselves, but if they are inhibited, tumors can form and growth can continue. Tumors and other diseases may have the same results, depending on the type of cells affected.
What are genes?
They’re certainly not “pieces” of paper that are stuck inside your body. They are the instructions the body reads. If the body can’t read them correctly, the result is disease.
- Diseases are caused when the body doesn’t have the correct tools to correct itself.
- Often, we don’t have the right nutrition or exercise, and we depend on other people to take care of us.
- If we don’t have enough knowledge about how to fix ourselves, we might as well just rely on other people to do it for us.
- That’s why most serious diseases tend to run in families.
How are genes found?
By studying one person, scientists have been able to decode the DNA (genetic code) and figure out what the genes do. Sometimes, diseases are completely linked to specific genes that were inherited from one parent to the next. Researchers have identified diseases related to obesity, heart disease, diabetes and Alzheimer’s among several others.
So, now you know what are genes? They’re not in your body. You won’t get “caught” with a test, unless your parents do an illegal drug. But if you eat a healthy diet, get plenty of exercise, and keep your body and mind in top shape, then you have nothing to worry about.
Scientists have also studied humans, to see how they behave once they get older. They find that most of the changes they see in older people, are actually due to genes. In other words, they “grow old gracefully.” And that has to do with longevity.

Want to know more about “what are genes?”
There’s much more to learn about this interesting subject, after we finish this article. For now, let’s look at how genes affect the body. For example, when you have a strong gene for heart disease, you can rest easy knowing that in the event of a health problem, your body will be better prepared than someone who doesn’t have that “short fuse.”
- Genes affect everything in your body.
- Some genes cause certain physical traits.
- Those traits are passed on to you.
- Others cause other changes in your body.
- These changes are also passed on.
So, just think about this for a moment. Just think about the next time that you get a cold or sore throat. Or the day you decide to start seeing spots under your eyes. All of these things are caused by changes in your genes. Think about what your future could be like, just depending on which genes you decide to pass on to your body.
