Alteration In The''Genes'

There are many problems that can cause alteration in the''genes''that would faltal.por mutation that is the importance of the genetic code is well and that just would not cause Downsyndrome or muscular dystrophy as damaging for humans to live with it.

The mutations occur in DNA and in the germ line cells when periods are duplicated in S (DNA synthesis) thatoccurs when a division is going to happen cellular There are three main types of mutations by changing bases'' ''These mutations concern only a triplet, and affect only one aminoacid. Depending on which amino acid is, the mutation is more or less important, for example if an amino acid that contributes to the active site of an enzyme would be "monumental." Onthe emergence of a STOP codon is another possibility that may arise from a STOP codon mutation where none existed before, then formed a truncated protein. Mutation is more severe themore the principle is and by deletion or duplication of bases in the 1st case is missing a base, since then it changes the reading frame.

 The genetic code is very importantbecause if it is some kind of disruption could be fatal to humans. This would result in muscular dystrophy, Down syndrome, Down syndrome among others. This it is quite common thisoccurs when the baby or animal cells produce an extra chromosome is 47 instead of 46.This causes the abnormal phenotype has features that have mental retardation. Muscular dystrophies aregenetic, are caused by defective genes. Genes direct the production of proteins that make up cells (in this case, muscle) and are required for essential functions of his life. Thisabnormal protein causes the muscles to weaken and atrophy. Unable to function correctly by the abnormal protein, muscle cells die and are replaced by fat and connective tissue.
