Can nonfunctional mrna be repaired
WebA mutation causing an addition or a deletion of one base pair resulted in the production of a nonfunctional mutant protein. The sequences of the normal and mutant proteins are given below. Was this mutation caused by an insertion or a deletion? Write the codons in the coding sequence of mRNA. If more than one codon is possible just write one. WebIf the DNA can be repaired, p53 activates other genes to fix the damage. If the DNA cannot be repaired, this protein prevents the cell from dividing and signals it to undergo apoptosis. By stopping cells with mutated or damaged DNA from dividing, p53 helps prevent the development of tumors.
