Gene expression is the process by which the information encoded in DNA is translated into functional proteins. It begins with transcription, where a specific segment of DNA is copied into messenger RNA (mRNA) by RNA polymerase. The mRNA then undergoes processing, including splicing and the addition of a 5' cap and poly-A tail, before being transported out of the nucleus into the cytoplasm. Finally, during translation, ribosomes read the mRNA sequence and synthesize a corresponding protein by linking together the appropriate amino acids in a specific order.

Shorter and can you dumb it down a little bit.
Gene expression is how cells turn DNA into proteins. It starts with transcription, where a section of DNA is copied into messenger RNA (mRNA). This mRNA then moves out of the cell nucleus and is translated by ribosomes into proteins, which are made by linking amino acids together based on the mRNA's instructions.
