Evolutionary insights in Amazonian turtles (Testudines, Podocnemididae): co-location of 5S rDNA and U2 snRNA and wide distribution of Tc1/Mariner [PDF]
Eukaryotic genomes exhibit substantial accumulation of repetitive DNA sequences. These sequences can participate in chromosomal reorganization events and undergo molecular cooption to interfere with the function and evolution of genomes.

Laparoscopic Anatomy of the Coelomic Cavity Organs in Female Red-Eared Slider (<i>Trachemys scripta Elegans</i>). [PDF]
Background: Turtles are one of the oldest reptiles and have evolved about 200 million years ago. One of them is the red‐eared slider (Trachemys scripta). These freshwater turtles are native to the southern United States and northern Mexico. However, they have become popular pets in Iran and many countries around the world. Due to being non‐native, they
