Document Summary
***quiz on nervous system, immune system, and genetics wednesday 3/29*** Review for final: four main types of biological molecules- nucleic acids (are dna and rna), Lipids (cell membrane, energy, cushioning, insulation), proteins (molecular machines), and. Rna= just a piece of dna with recipes for one single protein. Many scientists collaborated in the discovery of dnas structure. The nucleotide sequence in one strand therefore determines the sequence in the other strand and the two strands are complementary. A gene is a sequence of dna that encodes a specific protein. Ex: making brownies is a simple analogy to protein production. Cookbook= chromosome with multiple genes, brownie recipe= rna copy of one gene, ingredients= amino acids, and final product of brownies being done= protein. Dna and rna almost the same, dna stores rna and protein encoding information, transfers information to next generation of cells, while rna carries protein encoding information; helps make proteins; catalyzes some reactions.
