26 Functions of proteins and their synthesis 5

26 protein? Is there such a protein? Is it a 26S proteasome?

The 26S proteasome is widely distributed in the cytosol and nucleus of eukaryotic cells, mainly composed of the 20S core complex (CP) and the 19S regulatory particle (RP), which is responsible for the degradation of most proteins in the cell and plays a key regulatory role in almost all life activities. The assembly of the 26S proteasome is a very complex and highly organized process, in which different molecular chaperones, such as PAC1-4, UMP1, P27, P28, and S5B, are involved in recognition and regulation to ensure efficient and accurate proteasome assembly.

DNA or DNA

The genetic material of most organisms is DNA, and a few are RNA. If it's a high school problem, it's okay to just consider DNA as genetic material. There are gene fragments on DNA that control protein synthesis.

Nucleic acid. Nucleic acids are the genetic material of all living things, which can control heredity, variation and protein biosynthesis.

DNA Repository.

mRNA Messenger, Shipping Information.

tRNA carries nucleic acids and mRNA recognition.

rRNA forms ribosomes.

Nucleic acids play a key role in protein synthesis, mainly in the following aspects:

1. The sequence of the protein is determined by mRNA. The primary sequence information of a protein is determined by the sequence information of mRNA (messenger RNA) (ribonucleic acid), while the sequence information of mRNA is determined by DNA (gene of the protein).

Second, the factory of protein synthesis is ribosomes, and the main component of ribosomes is RNA (ribosomal RNA).

3. During translation, during protein elongation, the loading or introduction of amino acids is carried and introduced by TRNA.

Fourth, the level of regulation. Protein synthesis is a regulated process, on the one hand, during transcription, there are some cis-element regulation at the DNA level, such as enhancers, promoters, repressors, terminators, etc., which regulate the transcription of genes, and then regulate protein synthesis. On the other hand, at the RNA level, it is regulated by irna, microRNA, etc., whether these small RNAs can degrade mature mRNA and therefore regulate protein synthesis.

Nucleic acids direct protein synthesis through transcription, translation.

Enzymes all reduce the activation energy of reactants, and here it promotes the synthesis of amino acids into polypeptides.

rRNA is a component of ribosomes Ribosomal proteins are mostly basic proteins Positively charged under physiological pH conditions Therefore, they can bind to negatively charged RNAs under physiological pH conditions and transcate into stable ribosomes Ribosomes are the site of translation in protein synthesis The tRNA carries amino acids and binds to the codons on the mRNA Peptide bonds are formed on the ribosomes and are linked into proteins.

··· Is the transshipment called tRNA good felling?

RNA is the component that makes up ribosomes, and it is the nucleolus that is involved in ribosome synthesis.

rRNA is transmuter RNA.

Responsible for transporting amino acids during the translation process...

The mRNA is transcribed from the DNA template, and the mRNA is translated into the protein.

DNA controls protein synthesis.

RNA also has the role of an enzyme.

Like proteins, RNA can act as an enzyme to catalyze reactions and replicate itself.

Summarize high school textbooks:

1.There are a few enzymes that are RNA, so some RNA catalyze;

It has the effect of transporting amino acids;

is a constituent of ribosomes;

It has the function of transmitting genetic information;

5.Some RNA viruses undergo reverse transcription in the host cell and can replicate RNA.

Yes, the smooth endoplasmic reticulum synthetic protein is mainly used in the cell, and the rough endoplasmic reticulum synthetic protein is mainly used outside the cell.

The site of protein synthesis can only be ribosome, but the transport of secreted proteins requires the processing of endoplasmic reticulum.

The endoplasmic reticulum is the site of the synthesis of lipids.

No ribosome is the site for the synthesis of proteins.

However, endoplasmic reticulum has the role of processing and transporting proteins.
