Document Summary

Genetic basis of inheritance and biological evolution. Focuses on how evolution works at the level of phenotypes, genes, and population. Somatic cells: most cells in body (except sex cells) Cytoplasm: complex mix of membranes, molecules, and organelles. Nucleus: contains hereditary material, known as chromosomes. Paired rod-shaped structures in cell nucleus containing genes that transmit traits from generation to generation. In the nucleus-take shape of an x. Nucleic acid used to store genetic information that codes for synthesis of proteins. Four bases: adenine (a) guanine (g) cytosine (c) thymine (t) Sugar phosphate backbone (structurally stable), hydrogen-bonded bases (not structurally stable) T binds with a, g with c. Dictate synthesis of proteins that perform a wide variety of functions in body. Work with structures in cell (ribosomes) that are critical for manufacture in proteins. Transport amino acids to ribosomes for the creation of proteins. Linear sequences of amino acids; building blocks of cells.
