Explanation:
A synapse is the junction between two neurons (or neuron and effector) where the nerve impulse is transmitted from the presynaptic neuron to the postsynaptic neuron, usually via neurotransmitters. Axon carries impulses away from the cell body, dendrites receive signals, soma is the cell body. Synaptic transmission can be chemical or electrical.

Explanation:
Alexandre Yersin, a Swiss-French bacteriologist, discovered Yersinia pestis in 1894 during the Hong Kong plague epidemic. Koch discovered TB, Pasteur developed vaccines.

Explanation:
Restriction endonucleases are molecular scissors that recognize and cut DNA at specific, highly specific palindromic nucleotide sequences, creating fragments with sticky or blunt ends. DNA ligase is an enzyme that catalyzes the formation of phosphodiester bonds between adjacent DNA fragments, effectively joining or 'pasting' them together, crucial in recombinant DNA technology. PCR (Polymerase Chain Reaction) is used to exponentially amplify specific DNA segments, not to sequence them; DNA sequencing is a separate technique. Thus, statements 1 and 2 are correct.
