RNA Transcriptionany proteins play dual roles, and these are referred to as bifunctional (bifRNAs). Every single gene is transcribed into several copies of mRNA, and each mRNA molecule is capable of generating identical copies of a single protein. The amount of a protein synthesized from a gene is regulated during transcription and translation.作者: 真繁榮 時間: 2025-3-24 22:20 作者: 尾隨 時間: 2025-3-25 00:30
