Answer:
is a principle of geology that states that the geologic feature which cuts another is the younger of the two features. It is a relative dating technique in geology.
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.
According to the activation-synthesis theory of dreaming, the source of a dream is neuronal firing in the lower brain stem. It is also known as the medulla oblongata or just medulla. It is essential in processes like blood pressure and heart rate. Also, it is responsible in a number of reflexes in the body or the involuntary actions like coughing, sneezing and vomiting. It is said to contain cells that would turn REM on and off. From recent research, it is the part of the brain that is the origin of the electrical impulses where dreams are results. It is connected to other parts of the brain which controls memory, movement, hearing and vision.
