Answer:
Mutations in introns create alternative splicing site which in turn make mRNA with reduced or no translation.
Explanation:
Introns regulate the splicing of heterogenous RNA during post transcriptional modifications as well as affect the stability of mature mRNA. The stable mRNA is more likely to be translated into proteins. So, introns also regulate the translation of mRNA.
In human beta thalassemia, mutations in intron create alternative splicing sites which in turn affect the formation of beta globin chain of hemoglobin. Lack of beta globin chain reduces the amount of functional hemoglobin and causes anemia.
An exoskeleton made of chitin, jointed appendages and well developed sensory structures are characteristics that classify the Daphnia magna observed in lab as a member of the Crustacea.
Daphnia Magna is a small planktonic organism that belongs to the subclass Phyllopoda. It inhabits a variety of freshwater environments. Most common it is found in the northern hemisphere, and in South Africa.
Answer: i think the answer is b. To activate gene expression; the level of gene expression increases because repressors are not able to bind to the enhancer without the control element.
