Fingerprints
Your name is your identity. It gives you access to your bank account, social security number, and gives everyone else a way to know you, even in a crowd of people! In the same way that your name gives you a way to be recognized, fingerprints can provide a clue to your identity. They are crucial to understanding your genetics. The little lines reveal hints to your genes, and even can let you glimpse your DNA! It seems impossible, but it’s true. Fingerprints can identify you as easily as your name. First, it is complex to understand how fingerprints are formed. They are “friction ridges” (Rainis 18). Our fingerprints have tiny holes that release sweat (Rainis 18). Although it may sound odd, even your fingertips release sweat! Chalk it up to biology. Sweat can’t just accumulate there, so it has to get out. When this sweat is released, it mixes with oils on your fingers. By touching something, you leave oils there in the shape of your fingerprint patterns (Rainis 18). In both crime-solving T.V. shows and in real life, these imprints can be used to solve a murder, kidnapping, or other …show more content…
Every human has twenty-three chromosomes in their body (Funk and Wagnalls New World Encyclopedia). We all have anywhere from twenty thousand to twenty five thousand genes in our body, and these determine certain traits (Funk and Wagnalls New World Encyclopedia). Even though our DNA is shared with our parents with our parents and siblings, “All humans except for identical twins have unique DNA that can be used to identify them,” (geneticsthetech.org). Our genetics are similar, but they all are a bit different, with the notable exception of identical twins. Genetics are predetermined, yet they impact every part of our bodies and our health. By studying genetics, we can better understand human
