The Genetic Code

The Genetic Code. Gene -a section of DNA that codes for an amino acid sequence (on RNA), which is a building block for proteins. There are 20 different amino acids made up of three letter words (four letters to choose from-nitrogenous bases of RNA).

Why do we need RNA molecule for coding?

Why do we need RNA molecule for coding?. Nucleus membrane has small pores which let small molecules through to the cytoplasm. Double helix DNA molecule is too big to move through the pores. Amino acids and ribosome occur only outside the nucleus in the cytoplasm of the cell.
