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.

Nonsense mutation. Definition. noun. A form of point mutation resulting in a nonsense codon that does not code for an amino acid and leads to a protein product that is early truncated. Supplement. In nonsense mutations, the protein product from a sequence of DNA with a nonsense mutation is prematurely truncated, incomplete and often nonfunctional.Genetic disease ...upplement. In nonsense mutations, the protein product from a sequence of DNA with a nonsense mutation is prematurely truncated, incomplete and often nonfunctional. Genetic disease such as Duchenne muscular dystrophy is caused by a nonsense mutation in gene responsible for a specific protein, for example, dystrophin.
