WebApr 30, 2024 · The chromosome functions are given below They control the physiological behavior of an organism with the help of genes present in them. We know each chromosome is made up of DNA and this DNA by replication gives rise to messenger RNA (mRNA) which carries the genetic information in the form of code. WebRNA DNA polymerase is an enzyme that makes copies of the DNA sequence into RNA. Initiate transcription by recruiting and assisting RNA Polymerase, which muddles the promoter region. Transcription factors attach to the gene's promoter region to begin transcription. The promoter region marks the start of the gene's transcription process.
