Please help explain why they are false? thanks 1. Ribosomes are large RNA structures composed solely of rRNA. 2. Ribosomes are synthesized entirely in the cytoplasm. 3. A ribosome binds one tRNA at a time. 4. Ribosomes must bind to the 5′ cap before initiating translation 5. Misfolded proteins are delivered to the proteasome, where they are sequestered from the cytoplasm and can attempt to refold.

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...
