Amutation that knocked out the proofreading function of dna polymerase would result in see section 15.5 ( page 330) . a mutation that knocked out the proofreading function of dna polymerase would result in see section 15.5 ( page 330) . complete failure of dna replication no discernible effect on dna synthesis a lower-than-normal rate of dna synthesis errors a higher-than-normal rate of dna synthesis errors

A mutation is a spontaneous random sudden change that occurs in the genetic make up of an organisms, my be in the DNA or in the gene. In this case a mutation that knocked out proofreading function of DNA polymerase would result in a higher than normal rate of DNA synthesis error. Without the proofreading function, incorrect or the wrong nucleotides would be inserted about once every 100,000 bases instead of once every 10,000,000 bases which is the normal rate. 

The infrared (ir) and the ultraviolet(uv) represent the two extremities of the visible spectrum (400-700nm). while ir represents electromagnetic radiation with wavelengths longer than those of visible light, uv represents wavelengths shorter than visible light
