Document Summary
Ant100 - lecture 3 - principles of evolution. Genetic basis of inheritance and biological evolution. Focuses on how evolution works at level of phenotypes, genes and populations. Most cells in body except sex cells. Complex mix of membranes, molecules and tiny structures called organelles. Contains hereditary material, known as chromosomes: paired rod-shaped structures in cell nucleus containing genes that transmit traits from generation to generation. Nucleic acid used to store genetic information that codes for the synthesis of proteins. Four hydrogen-bonded bases: adenine (a), guanine (g), cytosine (c), thymine (t) A and t bond together; c and g bond together. Thymine is replaced by base uracil (u) Dictates synthesis of proteins that perform a wide variety of functions in the body. Works with structures in cell (ribosomes) that are critical for manufacture of proteins. Transports amino acids to ribosomes for the creation of proteins. Linear sequences of amino acids; building blocks of cells.
