transcriptions

Transcription is the biological process where a cell copies a segment of DNA into RNA, specifically messenger RNA (mRNA). This mRNA then carries the genetic instructions from the DNA in the nucleus to the cell's protein-making machinery in the cytoplasm. Think of it as copying a relevant chapter from a manual so it can be read elsewhere. Transcription is essential for gene expression, enabling cells to produce the specific proteins needed for growth, repair, and various functions. It’s a fundamental step in turning genetic information stored in DNA into functional proteins within living organisms.
