First, single nucleotide polymorphisms (or pronounced “snips”) are a variation in DNA sequences that occurs when one nucleotide, such as A, T or C, in a genome, differs between members or paired human chromosomes. SNPs must be less common than 1% of the population. SNPs could be the substitution of C with G in nucleotide sequencing AACGAT. This produces the sequence: AACCAT.
SNPs within genes can lead to different variants and alleles. This problem has one striking feature: SNPs occur both in noncoding regions of the genome and genes that are specifically in exons, introns, or both. Research shows that SNPs are found in approximately 10% of the human genome.
The second aspect to consider is the source for polymorphisms. Point mutations, which are changes in one nucleotide of the genome that create SNPs, are normal. One nucleotide can be replaced by another, while others may deleverage or add a single nucleotide. Single nucleotide Polymorphisms refer to variations in one nucleotide within a particular locus. They typically have two allles. SNPs are used to identify the functions of genes. This is where single nucleotide Polymorphisms (SNPs) can be extremely helpful. These SNPs can be used for tagging specific genotypes. SNPs are used to tag specific regions in DNA. It can also be used to locate genes on chromosomes. It is often found in non-coding areas that are near the genome. However, this could also be the part that contains single nucleotide mutations. It is not within the gene. It is not in the gene itself. For example, Alzheimer’s disease has the APOE genetic that encodes apolipoprotein E. (ApoE). There will be three variants of this gene if two SNPs occur in the same gene. These variants will be APOE??2,?3 or?4, and produce the proteins E3 and E4. Each variant has a different degree of Alzheimer’s susceptibility.
There are many hidden dangers in our world today, such as cancer. SNPs found in disease-related genes have been increasingly used as candidate candidates for finding causative variations. SNPs do not have any impact on development or health. These genentic differences are important for the study of human health.
SNPs are a way to predict a person’s reaction to drugs, susceptibility or risk of developing certain diseases. SNPs are also useful in tracking the family’s inheritance of certain diseases genes. Future research will identify SNPs that are associated with complex diseases like heart disease, diabetes, or cancer.
