ribosomes ?
The structure levels of a protein are primary (sequence of amino acids), secondary (alpha helices and beta sheets), tertiary (overall 3D shape of the protein), and quaternary (interactions between multiple protein subunits). Each level of structure is critical for the protein to perform its specific function.
ribosomes
Ribosomes have a small granular structure and are responsible for protein synthesis in cells. They are made of RNA and proteins and can be found in the cytoplasm or attached to the endoplasmic reticulum.
The small dot-like structure inside the nucleus is the nucleolus. It is responsible for producing ribosomes, which are essential for protein synthesis. The nucleolus is not surrounded by a membrane and can often be seen as a distinct structure within the nucleus.
The ribosomes are the part of the cell that are in charge of building proteins. This process is called Protein Biosynthesis. Inside ribosomes, the appropriate molecules join to form protein chains.
The ribosome translates the mRNA into protein.

Ribosomes have a small granular structure and are responsible for protein synthesis in cells. They are made of RNA and proteins and can be found in the cytoplasm or attached to the endoplasmic reticulum.
The primary structure is the formation of the amino acid sequence within a protein. It can be deduced in a laboratory by hydrolyzing the protein into small peptide chains, dehydrolyzing the protein into small peptide chains, determining their amino acid sequences, and then overlapping the sequences of small fragments created with different agents to reconstruct the whole polypeptide.
Small non-polar molecules may pass through a a semipermeable membrane but others require a protein channel.
