Changes in the DNA are reflected in the protein product. There is a correlation between what happens to the genetic sequence and the resulting protein sequence.
Blocks to bases, DNA Has Four Units.
Erwin Chargaff found that in DNA, the ratios of adenine (A) to thymine (T) and guanine (G) to cytosine (C) are equal. This parity is obvious in the final DNA structure.
A single nucleotide polymorphism, or SNP, occurs when two individuals in the population differ by a single letter in the DNA sequence.
Because it contains the directions for assembling the components of the cell, DNA is often thought of as the "instruction book" for assembling life.
