Detailed explanation-1: -Deoxyribonucleic acid (abbreviated DNA) is the molecule that carries genetic information for the development and functioning of an organism. DNA is made of two linked strands that wind around each other to resemble a twisted ladder-a shape known as a double helix.
Detailed explanation-2: -Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA).
Detailed explanation-3: -The type of RNA that contains the information for making a protein is called messenger RNA (mRNA) because it carries the information, or message, from the DNA out of the nucleus into the cytoplasm.
Detailed explanation-4: -DNA stores biological information in sequences of four bases of nucleic acid-adenine (A), thymine (T), cytosine (C) and guanine (G)-which are strung along ribbons of sugar-phosphate molecules in the shape of a double helix.
Detailed explanation-5: -mRNA molecules carry the genetic information needed to make proteins. They carry the information from the DNA in the nucleus of the cell to the cytoplasm where the proteins are made. Also called messenger RNA.
