DNA does not synthesize proteins itself, but it acts like a manager, delegating the various
tasks to a team of workers.
When a particular protein is needed by the cell, the nucleotide sequence of the appropriate
segment of a DNA molecule is first copied into another type of nucleic acid - RNA or
ribonucleic acid.
That segment of DNA is called a:
Gene; The resulting RNA copies are then used to direct the synthesis of the protein.
"central dogma"
The flow of genetic information in cells is from:
DNA to RNA to protein.
All cells express their genetic information this way.

Cells copy DNA to RNA in a process called:
Transcription.
Cells use the information in RNA to make protein in a process called:
Translation.
