Transcription:
* Nucleus: This is where transcription takes place. The DNA template is located here, and the process of creating mRNA from DNA happens within the nucleus.
* Nucleolus: A specialized region within the nucleus where ribosomal RNA (rRNA) is synthesized. rRNA is a crucial component of ribosomes.
Translation:
* Ribosomes: These are the sites of protein synthesis. Ribosomes read the mRNA sequence and translate it into a chain of amino acids, creating a protein.
* Cytoplasm: Ribosomes can be found free-floating in the cytoplasm or attached to the endoplasmic reticulum.
* Endoplasmic Reticulum (ER): This organelle is involved in the synthesis, folding, and modification of proteins.
* Rough ER: Ribosomes attached to the rough ER synthesize proteins that will be secreted from the cell, incorporated into membranes, or transported to other organelles.
* Golgi Apparatus: This organelle further processes, sorts, and packages proteins synthesized by the ER. It modifies and packages proteins for secretion or delivery to other organelles.
In summary:
* Transcription: DNA -> mRNA (happens in the nucleus)
* Translation: mRNA -> Protein (happens on ribosomes, which can be in the cytoplasm or attached to the ER)
