The basic unit of macro-evolution is SPECIE.
Macro-evolution refers to the theory of evolution in which changes that occur at or above the level of specie recognizes the need to better understand the patterns and processes which operate at the specie and higher levels within a hierarchical framework. Macro evolution is an evolutionary phenomenon, which can include any of the following: origination of new designs, large scale events such as extinction, broad trend and major transitions.

Makes a complimentary DNA strand from an RNA template. The process is known as reverse transcription as transcription involves DNA to RNA.

Muscle and nerve cells both contain the complete genome of the organism contained within their DNA. This means that both cells will contain all the same genes including the gene coding for the protein required in the sodium potassium pump. (Note the difference between cellular types and functions is the EXPRESSION of genes is different; all cells share the same genes but do not necessarily express them).
If both cells require the sodium/potassium pump and associated proteins than it is likely the exact same gene. Proteins are created through expression of genes. First the gene (a discrete section of DNA on a chromosome) is transcribed into an RNA message in the nucleus (RNA is similar to DNA and contains just the gene itself. Think of it as a post it note that has been copied from an encyclopedia of genes. Then the RNA is translated into a protein, which is a long chain of amino acids. The particular order and properties of the constituent amino acids that make up the protein cause it to coil up and form a 3 dimensional structure with properties that govern its particular function in the cell. In this case, the protein plays a key role in the sodium potassium pump. Protein synthesis is a fascinating topic and for more information, study up on the central dogma of genetics.
