Molecular Biologists By: Amanda, Elizabeth, and Abby
All living things are generally the same in the way that they are built • They all begin as single cells that reproduce • They come to a certain life span and get old and die • All plants and animals inherit genes from their parents • Hemoglobin and Myoglobin are found in almost every multi-celled animal
All living things are made up of only 20 kinds of amino acids • The DNA language in each and every living thing is the same.
Four different molecules that support the theory of evolution
Myoglobin and Hemoglobin • Found in mammals, birds, reptiles, amphibians, fish, worms, and mollescs.
Cytochrome • A protein that is involved in energy transfer and its changes are very slow
Fibrinopeptides • Involved in blood clotting and its changes are very fast
