The _electroencephalogram (EEG)_ is a device that takes advantage of the changing magnetic fields produced by the electrical activity of the brain to produce a record of neural activity in the awake brain.
C) DNA
Inside the nucleus, DNA and proteins together form chromosomes.
Wings would be different in human and pigeons.
RNA synthesis depends on RNA polymerases (RNAPs). This is the enzyme
that faciliates copying a sequence of DNA which is the first step
leading to gene expression. This multi-step process is important for
researchers to understand especially in relations to studying how
genetics influence disease processes.
