Transcription and Translation, ..

The information required to build resides on the in the form of sequences of , and has the form of triplets of bases called "codons" following the . Once the genetic information describing how to build a is to , it has to be "translated" into the "language" of the protein. The sequence of on the RNA forms a code for the building blocks of the protein. The word "translation" seems particularly appropriate for this process since the information contained in the DNA is translated from the four-character alphabet of the bases to the twenty-character alphabet of the amino acids.

Everything is Transcription initially begins with
a DNA strand as shown above Transcription really begins when an RNA
polymerase is brought into the picture.

it directs the synthesis of the protein, ..

This video shows Transcription and Translation of a gene

During Translation the tRNA
(Which is pink) will move through the
ribosome (Which is green) and as it
goes through it's anticodons will attach to the codons of the mRNA (Which is orange)
Also, when the tRNA goes through the ribosome it brings an amino acid with it and
drops it off and then the tRNA will exit the ribosome and goe to find another amino acid, so that it may repeat the process over again.

Translation begins with the
mRNA exiting the nucleus and
moving into the cytoplasm.
The cytoplasm is where the
process of translation takes place.

Protein synthesis requires two steps: transcription and translation

Translation is the last step in protein synthesis.
Translation involves decoding the mRNA that was created in Transcription to produce amino acids that come together to make a polypeptide chain, which makes up a protein.


Transcription is a process in protein synthesis
in which the genetic information from DNA is made
into a complimentary strand of mRNA.

6 Answers - What is protein synthesis and what are …

After translation, the protein passes into the channels of the rough endoplasmic reticulum (ER) for transportation. The protein is then passed from the rough ER to the Golgi apparatus inside tiny fluid-filled sacs, called vesicles. The Golgi apparatus is a system of , which are responsible for the modification, processing, and packaging of the proteins. The protein may have a carbohydrate added, to form a glycoprotein. The Golgi apparatus packages the protein in a secretory vesicle, which fuses with the cell membrane and releases the protein from the cell.

Protein Synthesis: Transcription & Translation

The process of translation can be divided into the stages of initiation, elongation, and termination. Initiation involves at least three other proteins called initiation factors to help bind the mRNA to the smaller subunit of the two-unit ribosome. It is bound to the correct location using the initiation codon AUG on the mRNA. The next phase is elongation, or adding other amino acids to the building polypeptide chain. According to Karp, a step of elongation can be accomplished in about 1/20 second, so a small protein of 400 units could be assembled in about 20 seconds! It is suggested that most of this time is used sampling the amino-acid-carrying tRNAs in the cytosol to find the ones for which there is a codon-anticodon match for the next codon along the mRNA pattern.

The above is a grossly oversimplified sketch of the translation process as it applies in a . See Karp for a more detailed treatment. The essentials that this illustration seeks to convey are that the ribosome uses the detailed sequence of codons on the and matches those codons to molecules which carry the corresponding amino acids. The translation process builds a polypeptide with the precise sequence of amino acids specified by the mRNA pattern. In , the translation process has many similarities but is of even greater complexity.
