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 ...
Recombinant DNA (rDNA) molecules are DNA molecules formed by laboratory methods of genetic recombination (such as molecular cloning) that bring together genetic material from multiple sources, creating sequences that would not otherwise be found in the genome.
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.
Nutritional epigenetics is a science that studies the effects of nutrition on gene expression and chromatin accessibility. [ 1 ] [ 2 ] It is a subcategory of nutritional genomics that focuses on the effects of bioactive food components on epigenetic events.
Nutritional science (also nutrition science, sometimes short nutrition, dated trophology [1]) is the science that studies the physiological process of nutrition (primarily human nutrition), interpreting the nutrients and other substances in food in relation to maintenance, growth, reproduction, health and disease of an organism.
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.
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 ...
Nicotinamide adenine dinucleotide consists of two nucleosides joined by pyrophosphate.The nucleosides each contain a ribose ring, one with adenine attached to the first carbon atom (the 1' position) (adenosine diphosphate ribose) and the other with nicotinamide at this position.
