Can nonfunctional mrna be repaired
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. WebFigure 6.8 (a) The role of p53 is to monitor DNA. If damage is detected, p53 triggers repair mechanisms. If repairs are unsuccessful, p53 signals apoptosis. (b) A cell with an abnormal p53 protein cannot repair damaged DNA and cannot signal apoptosis. Cells with abnormal p53 can become cancerous. (credit: modification of work by Thierry Soussi)

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.
WebNational Center for Biotechnology Information snapshot 100WebBefore the mRNA leaves the nucleus, it is given two protective “caps” that prevent the ends of the strand from degrading during its journey. 5′ and 3′ exonucleases can degrade unprotected RNAs. The 5′ cap, which is placed on the 5′ end of the mRNA, is usually composed of a methylated guanosine triphosphate molecule (GTP).
