Translation and RNAi – Genes to Proteins Ep 3

In the last article, we ended transcription with a strand of messenger RNA (mRNA) ready to leave the nucleus and travel to the ribosomes. The ribosomes are where translation happens - the next step in protein synthesis. Translation Translation begins with the mRNA strand settling between the two subunits of the ribosome. Each three base... Continue Reading →

Proteins – Biological Molecules Ep 9

We've already looked at the monomers that make up a protein: amino acids. But fully functioning proteins are often much more complex in structure than a simple polypeptide chain. Today we will look at the different levels of structure in proteins and some specific examples. Levels of protein structure So let's start with a quick... Continue Reading →

Amino Acids – Biological Molecules Ep 3

Amino acids are the building blocks of proteins. In this series we have already seen how nucleotides are the monomers joined together to make polynucleotide chains in DNA and RNA. Similarly, in proteins, amino acids are the monomers joined together to make polypeptide chains. Structure Firstly, let's look at the structure of an amino acid.... Continue Reading →
