“You’ll grow taller, don’t worry. It’s in your genes.”
We’ve all heard this, or a version of this, at least once in our lives, right? Do you also remember wondering what exactly ‘genes’ are and why they would make your body have certain characteristics?
Genes are sections of DNA that are part of every cell in our bodies. Different DNA combinations create different codes for each gene that act as instructions on what to do and how to behave for the gene. So each code will tell a gene if they should produce certain proteins, which in turn result in us having different body sizes and shapes, different hair colours and eye colours. Every person has anywhere between 20,000 to 25,000 genes in their body.
While genetics, which is the study of genes, is a complicated world, it does tell us many interesting things about how our bodies work. For example, did you know that scientists recently theorised that there may be people in the world who are genetically immune to COVID-19? This theory is based on how our genetic material reacts to the virus and the fact that genes can play an important role in whether you can get a disease or not.
Wondering what else our genes are capable of? Let’s find out:
