Satellite DNAs (satDNAs) are abundant repetitive sequences in eukaryotic genomes, traditionally associated with heterochromatic regions and regarded as "junk DNA" due to their rapid evolution and apparent lack of function. However, recent evidence suggests that some satDNAs can remain conserved over millions of years, either because they fulfill functional roles or simply by chance. This …
Eukaryotic genomes are mainly composed by a heterogeneous collection of repetitive DNA sequences, in which their functions, mostly, are not exactly known. Within this group, satellite DNAs (satDNAs) are unique tandemly repeated sequences that preferentially occupy heterochromatic regions. Historically, distinct techniques were applied to the characterization of particular satDNAs, like en…
Sex determination (SD) is a fundamental process in organisms, yet it remains to be fully elucidated in certain groups. Fish have become a model organism of interest for investigating sex determination mechanisms because of their high diversity, ranging from monofactorial to multifactorial systems. While sex determination is often genetically determined, there exist systems that cannot be …
Satellite DNAs (satDNAs) are abundant repetitive sequences in eukaryotic genomes, traditionally associated with heterochromatic regions and once considered "junk DNA" due to their rapid evolution and apparent lack of function. However, recent evidence suggests that some satDNAs may be conserved over millions of years, either because they play functional roles or by chance. This undergradu…
Satellite DNAs (satDNAs) are tandemly organized repetitive elements that constitute a significant fraction of the genetic material in eukaryotes, usually located in heterochromatic regions. Despite their significant abundance, these sequences do not exhibit a defined general function and were considered "junk DNA" for some time. With the popularization of high-throughput DNA sequencing me…
B chromosomes are supernumerary genomic elements found in eukaryotes, whose biology remains poorly understood. Previous studies have hinted at an association between these chromosomes and the sex of individuals in Psalidodon paranae, a fish species commonly known as "lambari," showing a significant difference in B chromosome frequency between sexes. Preliminary genomic analyses in this sp…
The identification of species through molecular tools such as COI (Cytochrome Oxidase I) is extremely important when the morphology of the organism is not sufficient for its identification. Sea cucumbers belong to the phylum Echinodermata and the class Holothuroidea, representing one of the most important marine resources among invertebrates, having great ecological importance, as they ar…
The As51 satellite DNA (satDNA), characterized over two decades ago, stands out as the primary chromosomal marker in species of the genera Astyanax and Psalidodon, extensively mapped across various species/populations. As a typical satDNA, this sequence accumulates in heterochromatic regions and often displays interpopulation variations in the number of chromosomal sites. Additionally, co…
