What is the directionality of RNA synthesis, and how is it related to the concept that RNA is synthesized from 5' to 3' end?

RNA synthesis occurs in a specific direction known as 5' to 3'. This means that RNA is synthesized starting from the 5' end and extending towards the 3' end. This directionality is important for the proper assembly of RNA molecules and is related to the concept that RNA is built in a specific order, similar to reading a book from the beginning to the end.
