RDNA or rDNA may stand for: ribosomal DNA, DNA sequence that codes for ribosomal RNA; recombinant DNA, DNA molecules; RDNA (microarchitecture), Radeon DNA, a GPU ...
In the large rDNA array, polymorphisms between rDNA repeat units are very low, indicating that rDNA tandem arrays are evolving through concerted evolution. [6] However, the mechanism of concerted evolution is imperfect, such that polymorphisms between repeats within an individual can occur at significant levels and may confound phylogenetic ...
Recombinant DNA is the general name for a piece of DNA that has been created by combining two or more fragments from different sources. Recombinant DNA is possible because DNA molecules from all organisms share the same chemical structure, differing only in the nucleotide sequence.

The 45S rDNA is organized into 5 clusters (each has 30–40 repeats) on chromosomes 13, 14, 15, 21, and 22. These are transcribed by RNA polymerase I . The DNA for the 5S subunit occurs in tandem arrays (~200–300 true 5S genes and many dispersed pseudogenes), the largest one on the chromosome 1q41-42. 5S rRNA is transcribed by RNA polymerase ...
The decrease in circular rDNA and the degradation of the amplified rDNA population in early embryo development indicated that the small circular molecules are homologous to the rDNA gene cluster, meaning that an abundance of rDNA sequences are not prone to generating circular chromosomes from random events like breakage of ligation. [15]
In biochemistry, a ribonucleotide is a nucleotide containing ribose as its pentose component. It is considered a molecular precursor of nucleic acids.Nucleotides are the basic building blocks of DNA and RNA.
