Answer:
DNA contains genes that can be read to create messenger RNA that directs the ribosome to build certain proteins as needed by specific cells or situations.
Explanation:
DNA is a nucleic acid that contains in its structure a specific sequence of nucleotides, whose quantity and order determine the genetic information of an individual. A chromosome consists of a DNA molecule, and each fragment of this molecule constitutes genes with specific instructions for determining structural and functional characteristics.
Transcription is the process by which DNA can be read and transcribed into messenger RNA (mRNA), a molecule that carries the genetic code to the ribosomes for protein synthesis, in a process called translation.
When a cell needs to synthesize a specific protein, transcription and translation mechanisms occur so that the protein can be synthesized.
