Document Summary
Understand microevolution: genetic basis of inheritance and biological evolution, population genetics, natural selection, adaptation. Understand macroevolution: speciation, how to read a cladogram, how evolution works on a grand scale, the modern synthesis. Focuses on how evolution works at level of phenotypes, genes and populations. Somatic cells: most cells in body (except sex cells) Cytoplasm: complex mix of membranes, molecules and tiny structures called organelles. Paired rod-shaped structures in cell nucleus containing genes that transmit traits from generation to generation. Deoxyribonucleic acid: nucleic avid used to store genetic information that codes for the synthesis of proteins. Four (structures) bases: adenine (a), gyanine (g), cytosine (c) and thymine (t). Dictate synthesis of proteins that perform a wide variety of functions in the body. Work with structure in cell (ribosomes) that are critical for manufacture of proteins. Transport amino acids to ribosomes for the creation of proteins. Linear sequences of amino acids, building blocks of cells.
