The structure of biomolecules controls their structure properties function and relationships with other biomolecules. One of the most important relationships is between a given biomolecule and water Which of the
following statements is true about the relationship between a given class of biomolecule and water?
O Large carbohydrate polymers will not be soluble or stable in an aqueous solution
O If the outer surface of a protein contains a high density of non-polar amino acids, it can be water soluble
O Since lipid chains are hydrophobic the presence or absence of water does not affect how they group
O Nucleic acids can hydrogen bond, which allows them to base-pair and to non-covalently bond with water

Keeping in mind the life cycle of bacteriophages, consider the following problem: during the reproductive cycle of a temperate bacteriophage, the viral dna inserts into the bacterial chromosome where the resultant prophage behaves much like a trojan horse. it can remain quiescent, or it can become lytic and initiate a burst of progeny viruses. several operons maintain the prophage state by interacting with a repressor that keeps the lytic cycle in check. insults (ultraviolet light, for example) to the bacterial cell lead to a partial breakdown of the repressor, which in turn causes the production of enzymes involved in the lytic cycle. as stated in this simple form, would you consider this system of regulation to be operating under positive or negative control?
