Slight differences in the color of feathers in
birds are the result of mutations. Mutation is process that occurs through a
long period of time. It is a process in which the genes’ structures changes
thus altering the physical characteristics and behaviors of species. This
results into variant forms that may be transmitted to the next generations of
species. Mutation is caused by an alteration of single base units in DNA, or
the deletion, insertion, or rearrangement of larger sections of the genes or
chromosomes. </span>

Our fingerprints are like our own dna that makes up our identity. Our fingerprints are like a serial code which can be scanned like the iPhone.
The mass is increased as two things are added together so the two masses of the two substances are added together.
DNA is composed of nucleotides, which are composed of three parts:
1. A five carbon carbohydrate (pentose)
Pentose is classified as a monosaccharide (simple carbohydrate), and its molecular formula is represented by 
. They are water soluble molecules with sweet taste. Monosaccharides may have from three carbon atoms (trioses) to six (hexoses). In DNA is present pentose (5 carbon atoms)
2. A nitrogenous base
Nitrogenous bases are ring-shaped compounds that contain nitrogen in their molecular structure. They are classified into two groups: purines and pyrimidines
The purine bases are adenine (A) and guanine (G). They are larger and contain more than one ring in their structure,.
The pyrimidines, cytosine (C), uracil (U) and thymine (T), are smaller and composed of a single ring.
3. One or more phosphate groups
A phosphate consists of a trivalent anion that contains one phosphorus atom and four oxygen atoms. Its molecular formula is expressed by 
.
