Russian tortoise, Steppe tortoise, Afghanistan tortoise, Four-toed tortoise and even Russian box turtle. It is found in Afghanistan, Northern Pakistan, Northern and Eastern Iran, North Western China and the Soviet territory Kazakhstan. Most Russian Tortoises found in the pet trade are from the territory of Uzbekistan.Its habitats are dry open landscapes.It is most commonly found in sand and clay deserts with sparse grasses and bushes. Russian tortoises are rarely found in dense grassy areas or cultivated fields (Paraskiv,1956; Kuzmin, 2001).ost Russian Tortoises found in the pet trade are from the territory of Uzbekistan.

During transcription, the enzyme RNA polymerase (green) uses DNA as a template to produce a pre-mRNA transcript (pink). The pre-mRNA is processed to form a mature mRNA molecule that can be translated to build the protein molecule (polypeptide) encoded by the original gene. Â© 2013 Nature Education All rights reserved.
Transcription is the process by which DNA is copied (transcribed) to mRNA, which carries the information needed for protein synthesis. Transcription takes place in two broad steps. First, pre-messenger RNA is formed, with the involvement of RNA polymerase enzymes.ranscription is the process by which DNA is copied (transcribed) to mRNA, which carries the information needed for protein synthesis.
