Question

Genetics: What is the importance of controlling gene expression in the molecular pathway from DNA to RNA to Protein in Eukaryotic cells?

Answer 1

One of the most important things in central dogma is the regulation of the pathways because if the regulation doesn't take place then it leads to uncontrolled growth and that leads to cancer. All the steps are important starting from DNA to MRNA that is transcription and this is the most important because mrna is the substrate for protein production. If mRNA is made in more amount then more protein is made. So, Mi RNA cells use for destruction of extra mrna. If proteins especially cell cycle proteins are not regulated then cell cycle is disturbed and lead to cancer.
