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.
Silent mutations - are caused by a point mutation & have no effect of the function because they code for the same amino acid. Missense mutations - are caused by a point mutation & result in a different amino acid to be placed in the protein. Nonsense mutations - a caused by a point mutation & cause a stop where there should not be one. Frameshift mutations - are caused by an insertion or deletion of a nucleotide causing the reading frame to shift & the protein to be too long or too short.
