Retroposons are repetitive DNA fragments which are inserted into chromosomes after they had been reverse transcribed from any RNA molecule. Difference between retroposons and retrotransposons [ edit ]
Rodentology is a branch of mammalogy for the study of rodents by a rodentologist. [1] The scientific group of rodents would include, but is not limited to, mice, rats, squirrels, etc. From the perspective of zoology , it investigates the behaviour, biology and classification of various rodent species.
LTR retrotransposons have direct long terminal repeats that range from ~100 bp to over 5 kb in size. LTR retrotransposons are further sub-classified into the Ty1-copia-like (Pseudoviridae), Ty3-like (Metaviridae, formally referred to as Gypsy-like, a name that is being considered for retirement [4]), and BEL-Pao-like (Belpaoviridae) groups based on both their degree of sequence similarity and ...
Caviomorpha is the rodent parvorder that unites all New World hystricognaths.It is supported by both fossil and molecular evidence. The Caviomorpha was for a time considered to be a separate order outside the Rodentia, but is now accepted as a genuine part of the rodents.

A tuco-tuco is a neotropical rodent in the family Ctenomyidae. [1] [2] Tuco-tucos belong to the only living genus of the family Ctenomyidae, Ctenomys, but they include approximately 60 different species. The common name, "tuco-tuco", comes from the "tuc-tuc" sound they make while they dig their burrows.
The rodent was first described based on material collected from the Barrancas de San Gregorio, Uruguay, a series of sea cliffs in the San José Department by Kiyú beach.The enormous fossils, catalogue number 28.VI.65.1 SPV-FHC, comprise a left mandibular (lower jaw) fragment which preserves the bottom part of the incisor, the premolar, the first two molars, a cavity corresponding to the third ...
