With Synbio Tech.’s industry-leading codon optimization software NGTM Codon, the gene expression level can be increased by several times or tens of times after optimization. The genes synthesized by our excellent synthetic biology Syno® platform were embedded into the best expression vector and it was verified by sequencing that the sequence of inserted recombinant plasmids were 100% correct. Synbio Tech. can provide customers conventional prokaryotic expression vector, such as pET, pCOLD and other common commercial vector series. In addition, Synbio Tech. also utilized powerful synthetic biology element construction function to optimize and reconstruct the pSYNO series prokaryotic expression vectors for you to choose from, including sumo, MBP, GST, Trx and tags promoting solubility and expression level. Please contact for details.

Protein synthesis, prokaryotes and eukaryotes - …

The prokaryotic expression system generally takes E. coli as the host cell. Since the cell has advantages like rapid proliferation, high expression, easy purification, good stability, strong anti-pollution ability and low cost, prokaryotic protein expression system is not only the most mature and reliable, but also the most commonly used, the most economical and effective expression system in the experiment of protein expression at present.

What is the difference between eukaryotic and prokaryotic protein synthesis?

Difference between Prokaryotic and Eukaryotic ..


In prokaryotes RNA processing is not necessary, but in eukaryotes the RNA must be processed before translation can occur.
3 main steps:
capping at 5' end
RNA splicing to remove introns
addition of polyA tail
Primary transcript is the initial product of transcription of an mRNA
Most genes have their protein-coding information interrupted by non coding sequences called
introns
The 5' end of the primary transcript (pre-mRNA) is synthesized first.
The 5' cap is a modified guanine nucleotide which attaches to the 5-end of the pre-mRNA.
The cap protects the RNA from being degraded by enzymes that degrade RNA at the 5' end.
RNA splicing removes introns and exons are joined.
exons
exons are a sequence within a primary transcript that remains in the RNA after RNA processing.
RNA splicing begins with helper proteins at intron/exon borders, defining the DNA that will be cut out.
Small nuclear ribonucleo proteins (snRNPs) recognize the splice sites.
A spliceosome is made up of proteins and RNA molecules that splices RNA by interacting with the ends of an RNA intron, releasing the intron and joining the two adjacent exons.
Synthesis of Poly-A tail
Poly-A tail is a stretch of adenine (A) nucleotides.
When a special poly-A attachment site in the pre-mRNA emerges, the transcript is cut there and the poly-A tail is attached to the exposed 3'end.
This completes the mRNA molecule which is ready to be transported to the cytoplasm.

On the other side it the opposite.

Eukaryotes change RNA after transcription by adding a 5'cap to the 5' end and a poly-A tail to the 3'end of the mRNA strand to protect them from some enzymes and help them attach to the ribosome.
Transcription is the process by which the information in a strand of DNA is copied into a new molecule of messenger RNA (mRNA).
Discovered the DNA double helix model, and the proposal of two DNA strands held by hydrogen bonds.

Using a centrifuge, DNA molecules separated with different isotopes and revealed a pattern that supports the semiconservative model of DNA replication.
Similarities
An isotope of an element is one that has more than the average number of neutrons for that element.
Transcription and Translation are both processes of protein synthesis in both Eukaryotic and Prokaryotic cells.
Both Eukaryotes and Prokaryotes require RNA polymerase to act on the DNA for transcription.
The end result of transcription and translation in both kinds of cells remain the same.
Each tRNA molecule has a specific anticodon at one end and a corresponding amino acid at the other.
