There are several types of RNA, each with specific roles:
mRNA (Messenger RNA): Carries the genetic code from DNA to the ribosome for protein synthesis. tRNA (Transfer RNA): Brings the appropriate amino acids to the ribosome during protein synthesis. rRNA (Ribosomal RNA): Forms the core of the ribosome's structure and catalyzes protein synthesis. miRNA (MicroRNA) and siRNA (Small Interfering RNA): Involved in gene regulation by degrading mRNA or inhibiting its translation.
