<h2>Nonsense Mutation</h2>
Explanation:
- Mutations are changes in a cell's DNA sequence. When a mutation happens in the coding sequence of a gene, the resulting protein is changed
- 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.Half-baked proteins that result from nonsense mutations are often nonfunctional or defective.
- The DNA sequence of the coding region of a gene is transcribed into a messenger RNA molecule, whose sequence is in turn read and decoded by the ribosome and transfers RNAs during translation.
- The sequence of a messenger RNA is read in groups of three nucleotides called codons. Each possible combination of the three RNA nucleotides (A, G, C and U) codes for an amino acid, translation start or translation stop. What you're looking at on screen is a table that shows what each codon means to the ribosome and transfer RNAs.
A. is the answer. Antibiotics kill bacteria which are living, but since viruses aren’t living, antibiotics will not work.
The Fluid Mosaic Model states that membranes are composed of a Phospholipid Bilayer with various protein molecules floating around within it. The 'Fluid' part represents how some parts of the membrane can move around freely, if they are not attached to other parts of the cell.
