The ribosomal DNA (abbreviated rDNA) consists of a group of ribosomal RNA encoding genes and related regulatory elements, and is widespread in similar configuration in all domains of life.

Ribosomal DNA (rDNA) refers to the genes responsible for encoding ribosomal RNA (rRNA). AI generated definition based on: Brenner's Encyclopedia of Genetics (Second Edition), 2013

The ribosomal DNA (rDNA) consists of multiple tandem arrayed rRNA-coding genes and organizes the nucleolus, a dynamic, phase-separated subnuclear compartment where rRNA synthesis, processing, and ribosome assembly takes place.

2025年1月25日 · Ribosomes are macromolecular machines found in all living cells that synthesize proteins by translating messenger RNA (mRNA). Located in the cytoplasm, ribosomes either float freely or attach to the endoplasmic reticulum in eukaryotic cells.Structurally, they consist of ribosomal RNA (rRNA) and proteins, forming two subunits: a smaller subunit for reading …

RNA molecules differ from DNA molecules in several important ways: They are single stranded rather than double stranded; their sugar component is a ribose rather than a deoxyribose; and they...

2019年5月20日 · Ribosomal DNA, or ribosomal deoxyribonucleic acid (rDNA), is the DNA that encodes ribosomal proteins that form ribosomes. This rDNA makes up a relatively small portion of human DNA, but its role is crucial for several processes.

In human cells, ribosomal DNA (rDNA) is arranged in ten clusters of multiple tandem repeats. These clusters are known as Nucleolus Organizing Regions (NORs) and situated on the short arms of the acrocentric chromosomes (#13, #14, #15, #21, #22).

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.

2022年3月8日 · With the advent of long-read sequencing, previously unresolvable genomic elements are being revisited in an effort to generate fully complete reference genomes. One such element is ribosomal DNA (rDNA), the highly conserved genomic region that encodes rRNAs.

2024年7月31日 · The ribosomal DNA (rDNA) constitutes a remarkably conserved DNA sequence within species, located in the area of the nucleolus, and responsible for coding three major types of rRNAs (18S, 5.8S and 28S).
