what is the function of ribosome,?
In biology, the nucleolus is, strictly speaking, a suborganelle of a cell nucleus which is an organelle Nucleolar organizers are special regions on some chromosomes that contain multiple copies of the genes encoding for rRNA the ribosomes which are involved in protein biosynthesis. Following synthesis, the rRNA is attached to the ribosomal subunits in the nucleus before transport through the nuclear pores
into the cytosol.
The function of ribosomes is to synthesize proteins by translating the genetic information from mRNA into amino acid sequences. This process occurs in the cytoplasm of a cell.
Ribosomes consist of two subunits, a large and small subunit, that come together during protein synthesis. The mRNA is fed through the ribosome and the ribosome reads the sequence of nucleotides and assembles the corresponding amino acids to create a polypeptide chain, which will eventually become a protein.
Ribosomes are found in both prokaryotic and eukaryotic cells. In prokaryotes, ribosomes are located in the cytoplasm, while in eukaryotes, they can be found in both the cytoplasm and on the endoplasmic reticulum.
Ribosomes play a crucial role in gene expression by translating the genetic information stored in DNA to create proteins. They are responsible for the formation of the polypeptide chain that makes up a protein, which is essential for the proper functioning of a cell.
In addition to their role in protein synthesis, ribosomes also play a role in regulating gene expression and can be involved in other cellular processes such as DNA repair and apoptosis. They are also involved in the synthesis of non-protein molecules, such as certain types of RNA.
