Document Summary
Genomes: where the genetic record of life is contained. Can tell us about demographic history as well as natural selection. Proto-languages: languages that can be traced back to one ancestral point. English, french, german, russian, and sanskrit = indo-european. Diploid genome- all humans are diploids, two copies of the genome in each of our somatic cells (somatic cells make up the tissue) Nucleotides: the fundamental building blocks in which dna is encoded. Mitochondria: where dna is also found in specialized organelles. Nuclear genome is wrapped around a chromatin, mitochondrial dna is not bound by proteins. Dna= deoxyribonucleic acid carries instructions for making the components of the cell provides a means for this set of instructions to be passed onto the daughter cell when the cell divides. Four varieties of nucleotides in dna called bases: adenine, guanine, cytosine, and. Each base is joined to a sugar molecule (deoxyribose) Each deoxyribose has a phosphate group attached to it.
