Homework Answers
Three types of RNA are
1. Messanger RNA (mRNA)
2. Transfer RNA (tRNA)
3. Ribosomal RNA (rRNA)
RNA polymerase is responsible for the synthesis of RNA (DNA
dependent RNA synthesis)
RNA polymerase adds a new nucleotide to the 3'-OH group of the
ribose sugar on the existing strand.

Please explain
Why is a cap added to MRNA, but not to 1RNA or RRNA? Each of the three types of RNA are transcribed by different RNA polymerases. Only RNA polymerase II, involved in mRNA synthesis, contains a domain capable of interacting with enzymes that form the cap. Transcription and processing of MRNA occur in the nucleus, where cap binding proteins are found. These proteins, which add and modify the cap, are not found in the cytoplasm, where tRNA and...
