Abstract:
Review and analysis of the experiments with Wastar rats in microgravity onboard "Cosmos" biosatellites allows to conclude that adaptive potentials of mammals in space flights lasting up to 1/50 th of their life span are enough for rapid elimination of microgravity-induced metabolic and structural alterations on return to Earth, for maintenance of adequate reactions to acute and chronic stressors in the post-flight period, for normal reproductive function and life span. Consideration is given to individual differences in body responses to the micro-g environment.

Transcription
Transcription is the process of synthesizing RNA from a DNA sequence by RNA polymerase. It is the first step in producing a protein from a gene sequence. Additionally, many other proteins and regulatory sequences are involved in the proper synthesis of messenger RNA (mRNA). Regulation of transcription is responsible for the differentiation of all the different types of cells and often for the proper cellular response to environmental signals.
