Detailed explanation-1: -The Alu sequence is known to occur about 1 million times in the human genome: it is the most frequent SINE.
Detailed explanation-2: -Scientists can compare the DNA of two organisms; the more similar the DNA, the more closely related the organisms.
Detailed explanation-3: -Human and chimp DNA is so similar because the two species are so closely related. Humans, chimps and bonobos descended from a single ancestor species that lived six or seven million years ago.
Detailed explanation-4: -The components that make up the genetic code are common to all organisms! Same NUCLEOTIDES, same BACKBONE same BASE-PAIRS, same HYDROGEN BONDS! The instructions for making proteins (and traits) are in the sequence of nucleotides!
