Viruses are infectious agents that can only replicate inside the living cells of an organism.
Molecular structure of DNA - Khan Academy
DNA, short for deoxyribonucleic acid, consists of nucleotides forming a double helix structure. Nucleotides contain a phosphate group, deoxyribose sugar, and a nitrogenous base. The bases, adenine, thymine, cytosine, and guanine, pair up through hydrogen bonds, creating the rungs of the DNA ladder.

Transcription is the process of copying a segment of DNA into RNA.

DNA (vídeo) - Khan Academy
O DNA, ou ácido desoxirribonucleico, é a base molecular da herança genética, sendo descoberto em meados de 1800 e compreendido em 1953 com a estrutura de dupla hélice. Composto por uma cadeiade açúcar-fosfato e pares de bases (adenina-timina, guanina-citosina), o DNA armazena informações genéticas, replica-se e expressa traços.
