Summary Introduction
To review:
The SNP (single
Introduction:
The SNPs are the biological markers used to identify the particular genes. Generally, they are not found in the genes or coding regions. They are usually found in the regions between the genes. A friend working in a research laboratory has discovered a tight association between an SNP allele and the disease she is studying. She inferred that this means the SNP allele must be the mutation that causes the disease.

Your first task though is to convince yourself that is true. The best way to do that is to start close to home. Find something in your house that is a product obtained directly from an invertebrate or only due to an invertebrate’s actions. Describe the product, its function and utility, as well as any human manufactured alternatives. Be sure to highlight the advantages of obtaining this directly from nature. Keep in mind, a product can be something you use, wear, eat, or enjoy for its visual appeal.arrow_forward
