WHAT HAPPENS WHEN PARTS OF THE GENE CHANGE?
- Mutations can occur in coding and non-coding regions of genes.
- Several types of mutations are known, such as insertions and deletions of DNA fragments, called INDELs, and point mutations, occurring only at one nucleotide.
- When these variations occur in at least 1% of the population, they are called polymorphisms or, more specifically, SNPs - Single Nucleotide Polymorphism.
- The identification of SNPs in each individual is of extreme importance since it is known they are involved in disease susceptibility.
- In January 2008, an international project - 1000 Genomes Project – was launched, aiming to identify genetic variability in the genomes of 1000 individuals.
- In this activity, we propose you identify the known genetic variability for the opsin gene, responsible for capturing the red color, and the consequences
these changes have on the perception of color.
