Document Summary
Cells divide to replace old or damaged cells. Ex: bones are completely new every 10 years. Look up: do animals get smaller bigger on islands, do scars disappear. Diploid parent cells -> diploid daughter cells. Credited to rosalind franklin (helped understand the structure which helps understand function), watson and crick understood dna more after seeing her images, and got the nobel prize Understand function replication and code for protein formation. Timing of evolutionary events by comparing dna of diff organisms, and causes. Sugar and phosphate backbone forming a double helix shape. Sequence of dna bases caring info for synthesizing a polypeptide (proteins) A small segment of dna that synthesize proteins. Dna letters (a,g,c,t) form 3 letter words?- triplets. Acts as words of a recipe for different amino acids, proteins are made of amino acids. Genetic code: most amino acids are coded by more than one triplet.
