The endoplasmic reticulum (ER), the main membrane system in eukaryotic cells, is the place where protein synthesis takes place. The model shows a section of the whole system in order to make the membrane structure visible and takes into account the difference between the rough ER (with the attached ribosomes in red) and the smooth ER. It is usual for the reticulum to completely surround the cell nucleus (white in the model).
The 'Central Dogma' of molecular biology is that 'DNA makes RNA makes protein'. This anime shows how molecular machines transcribe the genes in the DNA of every cell into portable RNA messages, how those messenger RNA are modified and exported from the nucleus, and finally how the RNA code is read to build proteins.
Is energy (ATP) required for protein synthesis?
The tRNA picks up specific from the cytoplasm and brings them into position on the surface of a ribosome where they can be joined together in specific order to make a specific protein.

Transcription is the process of making an RNA copy of a gene sequence. This copy, called a messenger RNA (mRNA) molecule, leaves the cell nucleus and enters the cytoplasm, where it directs the synthesis of the protein, which it encodes. Here is a more complete definition of transcription:
Translation is the process of translating the sequence of a messenger RNA (mRNA) molecule to a sequence of amino acids during protein synthesis. The genetic code describes the relationship between the sequence of base pairs in a gene and the corresponding amino acid sequence that it encodes. In the cell cytoplasm, the ribosome reads the sequence of the mRNA in groups of three bases to assemble the protein. Here is a more complete definition of translation:
Control of protein synthesis ..
Protein Synthesis Animation Video - tRNA is joined to the mRNA by a peptide bond. A tRNA moved into the Asite where the codons match the mRNA the. Need help with your Anatomy and Physiology I homework? In this learning activity you'll review how every protein molecule of an organism is synthesized by. Time-saving video on protein synthesis. Protein synthesis begins with a process called translation which occurs in the ribosomes. Protein synthesis is an.
RNA & Protein Synthesis - SlideShare
Jan 5, 2014. A collection of Protein Synthesis Animation videos, that cover the full protein synthesis process and have focus on some specific protein. Protein Synthesis. mRNA carries information condones which code for aminoacids. Aminoacids are brought to place of synthesis ribosome by tRNA transfer.
DNA Replication and Protein Synthesis - Biology Is Fun
It is during this translation process, when DNA/RNA language becomes protein language, that life reaches its full complexity.
The body contains tens of thousands of different proteins that control what happens in the body with an astounding precision.
