Ribosomal RNA (or rRNA) has a specific function. Ribosomes are made of ribosomal proteins and ribosomal RNA. Ribosomal RNA makes up about 60 percent of the ribosome's mass. They usually are composed of a large subunit and a small subunit. The subunits are synthesized in the nucleus by the...
**Ribosomes** are important for all living cells because they build proteins. Depending on the type of cell, any given cell contains between several thousand and a few million ribosomes. Since they are the protein-synthesizing machines of the cell, cells that require lots of proteins simply h...
A cell's genome contains the instructions for all the proteins the cell needs to function properly. However, the cell only makes proteins when copies of the gene for that protein are made, from the master copy instructions. These copies are messenger ribonucleic acids (mRNA), and ribosomes re...
2.1 Ribosomes Bacterial ribosomes are of 70S type and quite smaller than eukaryotic 80S types. They are made up of 2 subunits, the 50S, and 30S. Their main role is to synthesize bacterial proteins and enzymes. They are target sites for different antibiotics like erythromycin, macrolides, amino...

Question: What is the role of the nucleus in cell division? The Nucleus: In eukaryotic cells, the nucleus holds the DNA. DNA is arranged in long strands, each being called a chromosome. The normal human nucleus has 46 chromosomes. These chromosomes are identical in each cell, thanks to the...

The quaternary structure of RNA comes into play within certain macromolecules like theribosome, which builds proteins in the cell. Ribosomes are composed of multiple RNA chains, and the interactions between these chains must be precise and tightly regulated for the ribosome to function properly. In...
