Genes and Phenotype

Important concepts:

  • Gene
  • Phenotype

We are constantly seeing both news articles as well as scientific publications on new genes - the new gene for intelligence, cancer or happiness. So lets start at the beginning by figuring out what a gene is. Simply, its a way to refer to inherited traits.

There are a wide variety of traits that are controlled by genes. Flower color is a pretty obvious trait, so lets use a flower that comes in both white and red as an example. We call the specific ...

The basic but complex pieces of biology: DNA, RNA, & Proteins (aka Central Dogma)

Posted in:  ·  Introductory

All of biology functions around the core of DNA, RNA and Proteins or the so called Central Dogma of Molecular Biology. The key here is that you always go in the order of DNARNA→protein. You can’t jump from DNA to protein or visa versa; it just doesn’t happen. However, you don’t have to go all the way. Just because you made RNA doesn’t automatically mean it will be a protein. This is also not necessarily a one-to-one relationship. One RNA can be used to make several copies of the exact same protein.

Why do I care?
Because a gene can be looked at in each step of the DNARNA→protein progression. We look at all the different steps because how a gene is functioning can be regulated or changed at any point. However, in all cases, we are still interested in the gene..
