Answer:
c) It introduces a premature stop codon into the mRNA
Explanation:
Nonsense mutation is a type of point mutation (single nucleotide base is changed) which leads to premature stop codon. Stop codons are also called nonsense codons and that is way this type of mutation is called nonsense mutation. As a consequence, synthesized protein is incomplete and shorter than it should be (truncated protein), usually nonfunctional.
 
        
             
        
        
        
Answer:
Infection of a bacterium by a bacteriophage with subsequent production of more phage particles and lysis, or dissolution, of the cell. The viruses responsible are commonly called virulent phages. Lytic infection is one of the two major bacteriophage–bacterium relationships. 
Lysogeny, or the lysogenic cycle, is one of two cycles of viral reproduction. Lysogeny is characterized by integration of the bacteriophage nucleic acid into the host bacterium's genome or formation of a circular replicon in the bacterial cytoplasm.

Answer:
B
Explanation:
Neurotransmitters such as acetylcholine, epinephrine are important at a neuron-neuron junction called synapses. When an impulse reaches the end of one neuron, at the synapse, it causes the release of neurotransmitters from synaptic vesicle that diffuse across the synapse and when they bind to their reports on the other end. An impulse is then generated on the subsequent neuron that travels down the axon to the next synapse.
