Document Summary
Proteins: constructed from 20 amino acids linked by peptide bonds, form unbranched polymers which fold into precise three dimensional structure, proteins serve as signal molecules and as receptors for signal molecules, receptors covey to the cell that a signal has been received and initiates the cellular response, proteins play structural roles, allow mobility and provide defenses against environmental dangers, proteins serve as catalysts (enzymes) Nucleic acids: are the information keepers of the cell, stores and transfers information, contain instructions for all cellular functions and interactions, they are liner molecules, they are constructed form only four nucleotides, a nucleotide is made up of a 5c sugar, either a deoxyribose or a ribose, attached to a heterocyclic ring structure called a base and at least one phosphoryl group, there are two types of nucleic acid: deoxyribonucleic acid and ribonucleic acid, dna is constructed from four deoxyribonucleotides, differing in their bases; adenine (a), cytosine (c), thymine (t) and guanine (g)
