Ribosomal RNA (rRNA) Definition & Function

Ribosomes are compositionally heterogeneous between species and even within the same cell, as evidenced by the existence of cytoplasmic and mitochondria ribosomes within the same eukaryotic cells. Certain researchers have suggested that heterogeneity in the composition of ribosomal proteins in mammals is important for gene regulation, i.e., the specialized ribosome hypothesis. However, this hypothesis is controversial and the topic of ongoing research. WebThe ribosome units leave the nucleus through the nuclear pores and unite once in the cytoplasm for the purpose of protein synthesis.
