Ribosomal DNA - an overview | ScienceDirect Topics
Ribosomal DNA (rDNA) codes for the rRNAs used in the production of ribosomes, the sites of cellular protein synthesis. In most eukaryotes, ribosomal DNA consists of tandemly repeated arrays of four or five genes located at the nucleolus organizer region (NOR) of one or …
Ribosome - Definition, Function and Structure - Biology Dictionary
Apr 28, 2017 · A ribosome is a complex cellular mechanism used to translate genetic code into chains of amino acids. Long chains of amino acids fold and function as proteins in cells.
2.4D: Ribosomes - Biology LibreTexts
Aug 31, 2023 · Ribosomes are composed of ribosomal RNA (rRNA) and protein. Prokaryotic cells have three types of rRNA: 16S rRNA, 23S rRNA, and 5S rRNA. Like transfer RNA (tRNA), rRNAs use intrastrand H-bonding between complementary nucleotide bases to …
The function and synthesis of ribosomes - Nature
Jul 1, 2001 · Ribosomes consist of two subunits: one subunit (30S in bacteria and archaea, 40S in eukaryotes) decodes the mRNA, reading off the triplets of nucleotide that correspond to each amino acid; the...
First discovered, long out of sight, finally visible: ribosomal DNA
One such element is ribosomal DNA (rDNA), the highly conserved genomic region that encodes rRNAs. Genomic structure and content of the rDNA are variable in both prokarya and eukarya, posing interesting questions about the biology of rDNA.
