With the advent of technology, researchers have been able to focus their attention on the messengers of the brain, neurotransmitters. Researchers can introduce agonists to alter the activity level of a neurotransmitter in order to analyze the effects of introducing a substance that decreases the activity of a neurotransmitter.
Answer:
It transmits genetic information to the next generation
Explanation:
DNA stores information on how the cell should be made and ‘run’. This is why it is critical that its integrity is well preserved. Otherwise, mutations on DNA can be lethal to the cell. In higher cells, DNA is protected in the nucleolus. To pass down the genetic information, DNA is replicated by DNA polymerases and then during cell division, either copy of the pair goes to each of the two daughter cells.
