The transmission of genetic material from one generation to the next is necessary for the survival of a species. which statement describes one property that to ensure the reliable transmission of genetic information in living organisms? question 4 options: a) rna uses a nucleotide base called uracil to distinguish itself from dna. b) a pyrimidine base will only pair with the correct purine base. c) the two strands of a dna molecule cannot be separated. d) translation of mrna to assemble a protein is a reversible process.

Female luna moths (actias luna) attract males by emitting chemical signals that spread through the air. a male hundreds of meters away can detect these molecules and fly toward their source. the sensory organs responsible for this behavior are the comblike antennae visible in the photograph shown here. each filament of an antenna is equipped with thousands of receptor cells that detect the sex attractant. based on what you learned in this chapter, propose a hypothesis to account for the ability of the male moth to detect a specific molecule in the presence of many other molecules in the air. what predictions does your hypothesis make? design an experiment to test one of these predictions.
