In 2016, you paid $600 interest on a car loan. During 2016, you used the car 60% for business and 40% for personal purposes. You are claiming actual expenses on the car. You can only deduct $360 (60% Ã $600) for 2016 on Schedule C or C-EZ. The remaining interest of $240 is a nondeductible personal expense.
A nonsense mutation is a point mutation that introduces a premature stop codon into the part of the gene that encodes a protein. A stop codon is like a period at the end of a sentence: it instructs the ribosome to stop making the protein.
Nonsense Mutation. Gene mutation where a base-pair change in the DNA changes an mRNA codon for an amino acid to a stop codon. Instead of changing outcome, new mRNA codon is nonsense and codes for nothing. Causes premature chain termination.ase-Pair Substitution Mutation. Involves a change in the DNA such that one base pair is replaced by another. Can result in no change to protein, insignificant change, noticeable change.
