Summary
Centrosome-associated RNA (cnRNA) has been definitively proven to exist, prompting new research into its functions and origins. The presence of DNA in centrosomes remains uncertain, but cnRNA
Area of Science:
- Cell Biology
- Molecular Biology
- Genetics
Background:
- The presence of nucleic acids within centrosomes has been debated for decades.
- Previous reviews concluded no evidence for centrosomal DNA, but RNA remained a possibility.
- The question of centrosomal DNA remains unresolved, with inconclusive evidence.
Purpose of the Study:
- To investigate the functions and origins of centrosome-associated RNA (cnRNA).
- To explore cnRNA's potential role in mitotic center replication and spindle assembly.
- To consider if cnRNA represents a remnant genome from symbiogenesis.
Main Methods:
- Revisiting historical research lines on centrosome-associated nucleic acids.
- Analyzing existing evidence for centrosomal DNA and RNA.
- Formulating new research questions based on established findings.
Main Results:
- The existence of RNA at the centrosome has been conclusively demonstrated.
- Evidence for DNA within the centrosome remains inconclusive and contradictory.
- Historical data on centrosomal nucleic acids requires re-evaluation.
Conclusions:
- Centrosome-associated RNA (cnRNA) is a confirmed cellular component.
- Further research is needed to elucidate the functions and origins of cnRNA.
- The role of cnRNA in cell division and its evolutionary history are key areas for future study.

02:30Histone Variants at the Centromere
Histone variants are the histone proteins with structural and sequence variations. These variants may be regarded as “mutant” forms that replace their canonical histone counterparts in the nucleosomes. Specific post-translational modifications on the histone variants enable further chromatin complexity and regulate tissue-specific gene expression. The most common histone variants are from histone H2A, H2B, and linker histone H1 families. However, several variants of histone H3 variants are also...
01:13Centrioles and Centrosomes
Most animal cells comprise a pair of centrioles together called a centrosome. The cell duplicates its centrosome and contains two centrosomes side-by-side, which begin to move apart during the prophase. As the centrosomes migrate to two different sides of the cell, microtubules start extending from each centrosome toward the other end. The mitotic spindle is composed of the centrosomes and their emerging microtubules.

02:25Centrosome Duplication
The primary microtubule organizing center (MTOC) in animal cells is the centrosome. A centrosome has two cylindrical centrioles at its core. Each centriole consists of nine sets of three microtubules held together by proteins. The centrioles are positioned at right angles to each other and surrounded by a shapeless protein cloud called the pericentriolar matrix, or pericentriolar material (PCM).
To ensure that each daughter cell receives a centrosome after cell division, centrosome duplication...

02:53Ribosomal RNA Synthesis
Ribosome synthesis is a highly complex and coordinated process involving more than 200 assembly factors. The synthesis and processing of ribosomal components occurs not only in the nucleolus but also in the nucleoplasm and the cytoplasm of eukaryotic cells.
Ribosome biogenesis begins with the synthesis of 5S and 45S pre-rRNAs by distinct RNA polymerases. The primary transcripts are extensively processed and modified before they are bound and folded by ribosomal proteins and assembly factors,...

02:57piRNA - Piwi-interacting RNAs
PIWI-interacting RNAs, or piRNAs, are the most abundant short non-coding RNAs. More than 20,000 genes have been found in humans that code for piRNAs while only 2000 genes have been found for miRNAs. piRNAs can act at the transcriptional and post-transcriptional levels and have a vital role in silencing transposable elements present in germ cells. They are also involved in epigenetic silencing and activation. Previously, they were thought to function only in germ cells but new evidence suggests...
