$RNA$ is found everywhere- nucleus, nucleolus, mitochondria, chloroplasts, ribosomes, cytoplasm, etc.
$RNA$s are $3$ different types- m$RNA$, t$RNA$ and r$RNA$. m$RNA$ and t$RNA$ are found in the cytoplasm and r$RNA$ in the nucleus.
The ribosomes can be free within the cytoplasm of a cell or attached to the endoplasmic reticulum but do not present inside the nucleus.
$RNA$ and ribosomes act together resulting in the synthesis of proteins.
