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.
Synthesis. All RNA molecules are created by transcription, or making a copy of DNA. The protein that makes a copy of DNA is RNA polymerase. This protein is an enzyme that can read DNA and make an RNA copy. Transcription starts when the RNA polymerase enzyme binds DNA at a specific location called a promoter.
