Summary
Human centromeres exhibit significant genetic variation and novel structures, challenging current sequencing methods. Evolutionary analysis reveals rapid turnover of centromeric DNA sequences across species.
Area of Science:
- Genomics
- Evolutionary Biology
- Molecular Genetics
Background:
- Centromeres are crucial for chromosome segregation but are challenging to study due to repetitive sequences.
- Understanding centromeric variation is key to comprehending genome stability and evolution.
Conclusions:
- Human centromeres display substantial genetic and structural diversity, impacting genomic analysis.
- Novel alpha-satellite HORs have a monophyletic origin, allowing estimation of amplification and mutation rates.
- Centromeric evolution is characterized by rapid sequence turnover and species-specific adaptations.

4.4K
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...

02:40Chromosome Structure
22.9K
A functional eukaryotic chromosome must contain three elements: a centromere, telomeres, and numerous origins of replication.
The centromere is a DNA sequence that links sister chromatids. This is also where kinetochores, protein complexes to which spindle microtubules attach, are constructed after the chromosome is replicated. The kinetochores allow the spindle microtubules to move the chromosomes within the cell during cell division.
Telomeres consist of non-coding repetitive nucleotide...

3.3K
John H. Renwick first coined the term “synteny” in 1971, which refers to the genes present on the same chromosomes, even if they are not genetically linked. The species with common ancestry tend to show conserved syntenic regions. Therefore, the concept of synteny is nowadays used to describe the evolutionary relationship between species.

02:25Centrosome Duplication
4.1K
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).

01:13Centrioles and Centrosomes
2.8K
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.
