Solution
Gene expression is the process by which the instructions in our DNA are converted into a functional product, such as a protein. This process involves two main stages: transcription and translation.
In transcription, a segment of DNA is copied into RNA by the enzyme RNA polymerase. This RNA molecule then undergoes a process called splicing, where introns (non-coding regions) are removed and exons (coding regions) are joined together to form a mature messenger RNA (mRNA) molecule.
In translation, the mRNA molecule is read by a ribosome, and the genetic code it carries is used to synthesize a protein. Each set of three nucleotides in the mRNA, known as a codon, corresponds to a specific amino acid. The ribosome reads the codons and adds the corresponding amino acids to the growing protein chain.
Therefore, gene expression is the process that allows the genetic information stored in the DNA to be realized as a functional protein product.
