How does RNA "know" which DNA strand is the template strand?

RNA copies DNA strands through a process called transcription. This involves an enzyme called RNA polymerase that binds to the DNA and reads the genetic code to create a complementary RNA strand.
The purpose of RNA copying DNA is to create a messenger RNA (mRNA) molecule that can carry the genetic code from the DNA to the ribosomes, where it is used to make proteins.
RNA and DNA are both nucleic acids and contain genetic information, but they have different structures and functions. DNA is a double-stranded molecule, while RNA is a single-stranded molecule. DNA stores the genetic code, while RNA helps to carry and translate the code into proteins.
Yes, there are three main types of RNA: messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA). Each type has a specific role in the process of protein synthesis.
Yes, RNA can make mistakes when copying DNA, just like DNA can make mistakes when replicating itself. However, the cell has mechanisms in place to correct these mistakes and ensure the accuracy of the genetic code.
