If the 5’ splice site sequence changed from 5’- GUAAGU-3’ to 5’-GUAUGU-3’, predict the effect of the sequence change on U1 binding and U6 snRNP binding in an in vitro protein– RNA binding assay.

#Unit 3. Fundamental Processes

  1. The mutation will not change binding of U1 and on other hand this will likely enhance binding of the U6 snRNP with the 5’ splice site

  2. The mutation will likely cause an increase in binding of U1 and on other hand this will not change binding of the U6 snRNP with the 5’ splice site

  3. The mutation will likely cause a decrease in binding of U1 and on other hand this will likely enhance binding of the U6 snRNP with the 5’ splice site

  4. The mutation will likely cause a decrease in binding of U1 and on other hand this will not change binding of the U6 snRNP with the 5’ splice site

How can evolution select for phenotypes that postpone reproduction or sexual maturity?” There is often a trade-off between reproduction and maintenance, and in many species reproduction and senescence are closely linked. Recent studies of mice, Caenorhabditis elegans, and Drosophila suggest that there is a conserved genetic pathway that regulates aging and that it can indeed be selected for. This pathway involves the response to insulin and insulin-like growth factors, Name of these transcription factors are
