Figure 1. DNA is made up of a series of monomers called nucleotides. Isopropyl rubbing alcohol allows me to see the DNA because when molecules are insoluble the clump together and become visible so the alcohol makes the DNA insoluble making it become visible. Genes, along with other parts of our DNA that turn genes on and off, hold information for how our body develops and functions.

For the genes DNA to subsequently influence an inherited trait, the stored genetic information in the DNA in most cases is first transferred to a closely related nuclei acid, RNA or ribonucleic acid. While you may know of the double-helix structure of DNA, you can't see that structure with the naked eye. The authors pay attention to genetic basis. endobj %PDF-1.4 % This complementarity between adenine and cytosine nitrogenuos base pairs and between guanine and cytosine nitrogenuos base pase pairs, attracted to one another by hydrogen bonds, is critical to genetic function. Three examples of why scientists might need to indentify DNA are for genetic testing, body identification, and analysis of forensic evidence.

Variants of genes, called alleles, are responsible for differences in hair color, eye color, and earlobe shape. Hypothesis: Of those 60 percent, the proteins encoded by them are roughly 40 percent identical when we compare the amino acid sequence of the human protein to its equivalent in the banana, Brody adds. The two strands are held together by hydrogen bonds between adenine and thymine and between guanine and cytosine.
