Question

The human genome has been sequenced. Explain the significance of finding a miss se mutation in a conserved region of a gene. Explain whether & how the significance would change if you found a nonsense mutation in this region. Explain whether & how the significance would change if you found a missense mutation in an un observed region. The human genome has been sequenced. Explain the significance of finding a miss se mutation in a conserved region of a gene. Explain whether & how the significance would change if you found a nonsense mutation in this region. Explain whether & how the significance would change if you found a missense mutation in an un observed region.

Explanation / Answer

Mutation can occure at any segment of DNA, missense mutation is a point mutation in which a single nucleotide change results in a different amino acid.This amino acid substitution may have no effect or it may change the protein function.

Example: If missense mutation occures in the conserved region of a gene, (gene which is resposible for eye ball colour as black), the colour may changed into blue.

Nonsense Mutation: A nonsense mutation is a point mutation in a sequence of DNA that results in a premature stop codon, or a nonsense codon in the transcribed mRNA, and in a truncated, incomplete, and usually nonfunctional protein product. if nonsense mutation occures in the conserved region of a gene, (gene which is resposible for eye ball colour as black), it may caused colourless eyeballs or may caused blindness also.
