That monster is 48 letters long, still smoking the longest English words by a lot. We promised help pronouncing the formerly-longest German word at the beginning of the article, so here it is. Let us know how you do in the comments below! Share 0
Ribonucleic acid, or RNA is one of the three major biological macromolecules that are essential for all known forms of life (along with DNA and proteins). central tenet of molecular biology states that the flow of genetic information in a cell is from DNA through RNA to proteins: âDNA makes RNA makes proteinâ.
RNA is very similar to DNA, but differs in a few important structural details: RNA is single stranded, while DNA is double stranded. Also, RNA nucleotides contain ribose sugars while DNA contains deoxyribose and RNA uses predominantly uracil instead of thymine present in DNA. RNA is transcribed from DNA by enzymes called RNA polymerases and further processed by other enzymes. RNA serves as the template for translation of genes into proteins, transferring amino acids to the ribosome to form proteins, and also translating the transcript into proteins.
