Extensive research over the years may lead us to believe that we have a comprehensive understanding of life on Earth, particularly its fundamental forms. Nevertheless, nature continues to conceal numerous mysteries, even within the realm of known species. A prime illustration of this is when researchers unveiled 71 previously unknown species across five continents and three oceans just a few years back. This serves as a reminder that there is still much to uncover when it comes to the diversity of life on our planet.
What is DNA?
The structure of the DNA
The genetic code
Nucleotides always pair up the same way, like A with T and G with C. If we know the sequence on one side, we can figure out the sequence on the other side. Nucleotides are like a code with four bases, but what does it mean? Well, proteins are made up of 20 different amino acids, and they have a complex structure that can be broken down into a sequence of amino acids.The Genetic Code
Characteristic of Genetic Code
- The genetic code is the set of rules by which a linear sequence of nucleotides specifies the linear sequence of a polypeptide.
- That is, they specify how the nucleotide sequence of an mRNA is translated into the amino acid sequence of a polypeptide.
- Thus, the relationship between the nucleotide sequence of the mRNA and the amino acid sequence of the polypeptide is the genetic code.
- The nucleotide sequence is read as triplets called codons.
