What Are Ribosomes? - Definition, Structure and its Functions

WebBased on the diversity of ribosomal RNA sequences, one can explore the structure of the microbiome in terms of presence and relative abundance. The conventional approach involves cloning full-length genes after PCR (with primers amplifying the target gene from a wide range of micro-organisms), followed by sequencing. Universally conserved secondary structural elements in rRNA among different species show that these sequences are some of the oldest discovered. They serve critical roles in forming the catalytic sites of translation of mRNA. During translation of mRNA, rRNA functions to bind both mRNA and tRNA to facilitate the process of translating mRNA's codon sequence into amino acids. rRNA init… WebA ribosome is basically a very complicated but elegant micro-‘machine’ for producing proteins.
