What is Genetics and Why It is Important to Us?

Genetics is the study of genes and this article will go over how we study genes and why it is important to us as a society. With advances in pharmacology and stem cell research, we can help eliminate diseases in our world and even help end world hunger. With genetics, we can help create a more perfect world.

All life is created by the building blocks of DNA. DNA is created by four nucleotides Adenine, Guanine, Thymine, Cytosine. Variants of the order of these nucleotides give rise to all the diversity of life on our planet. Hereditary information are passed through genes in our chromosomes. Humans inherit half of their chromosomes from their mother and the other half from their father. Even the sex of the child depends on what chromosomes the child inherits.

Genetics is the study of genes and by studying genes we can solve a lot of mysteries of the human body and find cures for diseases. The process that most genes are encoded in is transcription and translation. In transcription DNA is transcribed into RNA and in translation this RNA is translated into DNA. The nucleotides are read in reading framed of 3 nucleotides. These combinations of 3 nucleotides are called codons. For the most part DNA doesn't change but sometimes there can be mutations in the translation. These mutations are the driving force of evolution. When these mutations are favored in nature, they are passed on more readily and the less favored genes are passed on less and less. Through the course of millions of years, certain traits are passed on more readily and certain ones go extinct.

Geneticists study genes through the process of genetic dissection, which is a biological function can be picked apart through the use of mutations- each mutation represents another gene in the overall program behind the function in question. There is evidence that we are still evolving. Who knows where we will be in few million years? The study of genes is important because it gives us the story of our past and helps predict the course of our future. Also with advances in pharmacology and medicine, we can use genetics to eradicate certain diseases from our populations. In the future we will very much rely on artificially produced resources like our crops and maybe even animals. Genetics can help us potentially end world hunger and strive for a better earth. There are many problems on earth and studying humans and animals on a molecular level can help bring us some clarity and solve many issues that we are having. Having a strong understanding of genetics will help us weed out possible solution to our problems so we can move onto other important things.
