These chunks of information are the genes. Information in the gene, which is just a small part of DNA, is copied into a molecule called messenger ribonucleic acid (mRNA). RNA makes a template for protein synthesis. RNA then uses this information to direct the creation of the proteins that do the cell’s work. The process by which information from DNA is copied into RNA begins when the double-stranded DNA “unzips,” forming two single strands. One of these strands serves as a “template,” or model, for the synthesis of the RNA.
Everyday things that take planning become difficult. The individual may begin to lose track of the steps involved in playing a game or making a telephone call.

Depression symptoms; someone with AD may have rapid mood swings that go from calm to tears to anger for no apparent reason. At times, everyone feels sad, but typically a reason for the sadness is apparent.
The RNA created by transcription is called messenger RNA because it carries this information from the cell nucleus, where DNA is found, to the cytoplasm, where protein synthesis takes place. Remember that DNA holds the blueprint of heredity, but does not directly participate in doing the work. The work of making proteins, the building blocks of life, is done by RNA. DNA is made up of subunits called nucleotides, which consist of a nitrogen- containing base, a phosphate molecule, and a sugar molecule.
