Answer:
There is no scientific evidence to prove that people with schizophrenia ingest dopamine capable of accumulating excess in the body.
Explanation:
Although you did not specify that your question is associated with the origin of schizophrenia in people, we can see that this is the main topic of your question, due to its context. This is because scientists have been striving to find the origin of this disease, in order to be able to combat it in the early stages. Although many scientists believe that the origin of this disease is associated with excessive intake of dopamine, there is not strong enough scientific evidence to show that this is true. Because of this lack of evidence, filmmakers have focused on associating the origin of the disease with the sensitivity of the dopamine receptor and not with the dopain itself.
Answer:
In normal conditions, introns serve following functions in the body of an organism:
1) They contain genes of miRNA which are known as Mirtrons, reverse transcriptase, endonucleases, transposase etc.
2) It is because of presence of introns that alternative splicing of mRNA is possible. The sex determination in drosophila is based on alternative splicing.
Apart from this, alternative splicing can be useful and beneficial in an unforeseen situation such as an environmental problem which is faced by the organism for the first time.
Explanation:
Alternative splicing is an important mechanism because with the help of alternative splicing different type of proteins can be synthesized from the same pre mRNA transcript. In case suddenly the surrounding environment of an organism is changed and the environmental conditions have become extremely harsh due to which organism's life is at stake, in such situation organism may make a different type of protein through alternative splicing which can help the organism in survival.
Default splicing in Drosophila leads to the development of male off-spring while female off-spring is produced as a result of alternative splicing.
Groundwater is the largest available source of freshwater - up to 90%. It supplies drinking water especially to rural areas. They are also used to irrigate crops.
