"Genes contain the information that is required to express a particular trait." Explain.

(N/A) Genes are segments of $DNA$ that carry the genetic information required for the synthesis of specific proteins or enzymes.
According to the central dogma of molecular biology, the expression of a trait occurs through the following steps:
$1$. Transcription: The genetic information stored in the $DNA$ (gene) is transcribed into $mRNA$.
$2$. Translation: The $mRNA$ is then translated into a specific protein or enzyme.
$3$. Trait Expression: The synthesized protein may directly function as a structural component or trait, or the enzyme may catalyze a reaction on a specific substrate to produce a product, which ultimately manifests as a particular phenotypic trait.
