Understand that RNA, or ribonucleic acid, is a crucial molecule involved in various cellular processes, including protein synthesis and gene expression.
Recognize that in eukaryotic cells, RNA is synthesized in the nucleus where DNA is transcribed into RNA.
Note that after transcription, RNA molecules, such as messenger RNA (mRNA), are transported from the nucleus to the cytoplasm.
In the cytoplasm, mRNA is translated into proteins by ribosomes, which are also composed of ribosomal RNA (rRNA) and proteins.
Remember that RNA can also be found in organelles like mitochondria and chloroplasts, but the primary locations are the nucleus and cytoplasm.
