what is structure of ribozymes
Answers
The ribosome (/ˈraɪbəˌsoʊm, -boʊ-/[1]) is a complex molecular machine, found within all living cells, that serves as the site of biological protein synthesis (translation). Ribosomes link amino acids together in the order specified by messenger RNA (mRNA) molecules. Ribosomes consist of two major components: the small ribosomal subunits, which read the RNA, and the large subunits, which join amino acids to form a polypeptide chain. Each subunit comprises one or more ribosomal RNA (rRNA) molecules and a variety of ribosomal proteins (r-protein or rProtein[2][3][4]). The ribosomes and associated molecules are also known as the translational apparatus.

Components of a typical animal cell:
Nucleolus
Nucleus
Ribosome (little dots)
Vesicle
Rough endoplasmic reticulum
Golgi apparatus (or "Golgi body")
Cytoskeleton
Smooth endoplasmic reticulum
Mitochondrion
Vacuole
Cytosol (fluid that contains organelles, comprising the cytoplasm)
Lysosome
Centrosome
Cell membrane
Figure 1: Ribosomes assemble polymeric protein molecules whose sequence is controlled by the sequence of messenger RNA molecules. This is required by all living cells and associated viruses.
