The three main types of RNA directly involved in protein synthesis are messenger RNA (mRNA), ribosomal RNA (rRNA), and transfer RNA (tRNA). The mRNA carries the message from the DNA, which controls all of the cellular activities in a cell. In prokaryotes and eukaryotes, tRNA and rRNA are encoded in the DNA, then copied into long RNA molecules that are cut to release smaller fragments containing the individual mature RNA species.
"AUG" actually corresponds to a region of code on mRNA and is NOT an amino acid. The tRNA that has the anticodon 5' CAU 3' and recognizes AUG is a tRNA charged with Methionine. Therefore, methionine is the first amino acid incorporated into a growing polypeptide. Note this is true for only eukaryotes, prokaryotes have N-formyl methionine as their first amino acid.
During protein synthesis, the amino acids are linked together by peptide bonds. This process is carried out by the ribosomes.
protein synthesis
Proteins are produced in all cells by protein synthesis. It requires the mRNA molecule produced from DNA in nucleus. Once it is transported to cytoplasm, ribosomes and tRNA molecules and enzymes will carry out protein synthesis.
One way that protein synthesis differs between prokaryotes and eukaryotes is that gene groups that produce proteins are organized into operons in prokaryotes, but they are not organized into operons in eukaryotes. Also, protein synthesis in eukaryotes involves more protein and is a more intricate process than in prokaryotes.
Prokaryotes have ribosomes that are necessary for protein synthesis. The ribosomes found in eukaryotes are larger compared to those found in prokaryotes.
use codons to determine polypeptide sequences
In prokaryotes, RNA synthesis and protein synthesis takes place in the cytoplasm. In eukaryotes, RNA is produced in the cells nucleus and then moves to the cytoplasm to play a role in the production of protein.
In prokaryotic organisms, most of the control over protein synthesis occurs at the level of transcription initiation. This is often true for eukaryotes as well.
ribosomes are responsible for protein synthesis in a cell. prokaryotes consists of 70s type of ribosome whereas eukaryotes consists of 80s type of ribosome.
Eukaryotic cells have two types of endoplasmic reticulum: Smooth ER (SER); Rough ER (RER).
In the cytoplasm.
Protein synthesis occurs in cellular structures called ribosomes , found out-side the nucleus. The process by which genetic information is transferred from the nucleus to the ribosomes is called transcription. During transcription, a strand of ribonucleic acid (RNA) is synthesized.
AUG
The ribosomes are the small organelles responsible for protein synthesis. They are found in both eukaryotic and prokaryotic cells, but are smaller in prokaryotic cells (70s vs 80s).
The major difference between prokaryotes and eukaryotes is the presence, in eukaryotes, of a cell nucleus. This nucleus contains the DNA, bound in chromosomes, of eukaryotic cells, where it is transcribed to mRNA which is cut and spliced before being passed to the ribosomes for protein synthesis. There are about 80 subunits in the ribosomes. Prokaryotes. on the other hand have a different structure in their DNA and also contain small pieces of DNA called plasmids. There is no cutting and splicing of the mRNA and there are only about 70 subunits in the ribosomes.
