Replication errors result in mutations. Sometimes these mutations are not carried forward into the next cell division. If the change is deleterious, then cell death or the inability to successfully replicate could result.
The effect of a mutation may not be seen. An example would be if the error occurs in a non-coding region (genes code for protein products).Scientists can look at the mutation rate in these non-coding regions to determine how distantly related organisms are.
A single, or point, mutation within a gene may not cause any difference in protein product because the genetic code is degenerate. Each codon consists of three nucleotides. A codon codes for either an amino acid (building block of a protein) or a start or stop signal. There are 16 amino acids yet 64 combinations are possible with 3 nucleotides in 3 codon sets. Therefore multiple combinations code for the same amino acid. For example: Glycine is coded for by GGU, GGC, GGA, and GGG.
Even if the mutation results in a change in the amino acid produced, there may not be a phenotypic change because the final protein product may not be substantially different.

The result is called a mutation, and the gene will be carried on for generations. Some mutations are so big that the animal evolves, a type of mutation that allows animals with that charateristic to live.

Mutations; however not all mutations will affect the phenotypic expression and replication of the genetic material also involves a corrective mechanism

gene mutations(point mutations or frameshift mutations)point mutations includes substitution which does not create dramatic affect among the overall reading pattern, but frameshift mutations like insertion or deletion do.mutations that cause dram tic change are most likely harmful resulting in defective proteins/gene activity. they can cause cancer and a variety of genetic disorders

AS FAR AS POSSIBLE THE DNA-POLYMERASE 3 ENZYME OF THE DNA REPLICATION PROCESS DOES 3'TO 5' EXONUCLEASE ACTIVITY- MEANS IT REMOVES THE ERROR REGIONS.
BESIDES THIS IF THE ERROR STILL CONTINUE THEN IT RESULTS IN MUTATIONS WHICH CAUSE CANCER AND MANY OTHER DISEASE LIKE TURNERS SYNDROME , TRISOMY 31, TRISOMY XXX ETC.
THEY CAN ALSO BE LETHAL OR LIFE TAKING.
