DNA is long double stranded molecule that is made out of 4 nucleotides - A, T, C, G. Messenger RNA (mRNA) is shorter single stranded molecule also made out 4 nucleotides, but this time it is A, U, C, G. This U (uracil) nucleotide is RNA equivalent to T (thymine) nucleotide in DNA. Proteins are also single stranded molecules but they are not made out of nucleotides. This is why process of producing protein based on RNA is called translation - we are translating into a completely different kind of chemical. Building blocks of proteins are called amino acids. There are 20 different amino acids that are used in living organisms that we know. There is many more amino acids as chemical molecules, but they’re 20 that are used in in life.

Personal note These notes are to some extent similar to notes about genes since transcription is process of creating RNA from gene part of DNA. I will keep duplicate parts in both notes (and just use some references) so they can bring slightly different view and maybe better overall understanding.

DNA is a nucleic acid molecule that is used to store information within cells. This information is stored in a sequence of nucleotides which are the building blocks of DNA.

Most of the organisms on Earth have just one cell and whole self sufficient organism is contained in it. In higher multicellular organisms such as plants, humans etc., there is a specialisation of cells - different cells might do a specific job - and all of them together are needed for organism to survive. Even single cell is dependent on products of different cell types to survive.
