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 architecture by AMD; Reformed Druids of North America, an American Neo-Druidic organization
The rDNA transcription tracts have low rate of polymorphism among species, which allows interspecific comparison to elucidate phylogenetic relationship using only a few specimens. Coding regions of rDNA are highly conserved among species but ITS regions are variable due to insertions, deletions, and point mutations.
The Miller-Keane Encyclopedia & Dictionary of Medicine, Nursing, and Allied Health is written for use by students and health care providers including medics, nurses, and paramedics. The entries are alphabetical and compiled with multidisciplinary collaboration.
In 2007 the concept of the default mode was criticized as not being useful for understanding brain function, on the grounds that a simpler hypothesis is that a resting brain actually does more processing than a brain doing certain "demanding" tasks, and that there is no special significance to the intrinsic activity of the resting brain.

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.

18S ribosomal RNA (abbreviated 18S rRNA) is a part of the ribosomal RNA in eukaryotes.It is a component of the Eukaryotic small ribosomal subunit (40S) and the cytosolic homologue of both the 12S rRNA in mitochondria and the 16S rRNA in plastids and prokaryotes.
Not only does STR analysis use less of a sample to analyze DNA, but it also is a part of a larger process called Polymerase Chain Reaction (PCR). PCR is a process that can be used to quickly reproduce up to a billion copies of a singular segment of DNA.
