Transports amino acids to the ribosome for protein assembly

The cellular structure responsible for protein synthesis is the ribosome. Ribosomes are small, complex structures made up of RNA and proteins. They can be found freely floating in the cytoplasm or attached to the endoplasmic reticulum. Ribosomes play a crucial role in the process of translation, where they receive instructions from the DNA in the nucleus through messenger RNA (mRNA) and use these instructions to assemble amino acids into proteins. To find this answer, you can refer to any basic biology textbook or educational website that covers the topic of protein synthesis.
