Detailed explanation-1: -During the process of transcription, the information stored in a gene’s DNA is passed to a similar molecule called RNA (ribonucleic acid) in the cell nucleus. Both RNA and DNA are made up of a chain of building blocks called nucleotides, but they have slightly different chemical properties.

Detailed explanation-2: -Deoxyribonucleic acid (DNA) is a molecule that contains the biological instructions that make each species unique. DNA, along with the instructions it contains, is passed from adult organisms to their offspring during reproduction.

Detailed explanation-3: -DNA (deoxyribonucleic acid) is the carrier of genetic information in a cell. DNA stores genetic information. This genetic information is copied and transmitted from the parent cell to the daughter cells during the process of cell division.

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: -DNA encodes information through the order, or sequence, of the nucleotides along each strand. Each base-A, C, T, or G-can be considered as a letter in a four-letter alphabet that spells out biological messages in the chemical structure of the DNA.
