<span>Spilled oil can harm living things because its chemical constituents are poisonous. This can affect organisms both from internal exposure to oil through ingestion or inhalation and from external exposure through skin and eye irritation. Oil can also smother some small species of fish or invertebrates and coat feathers and fur, reducing birds' and mammals' ability to maintain their body temperatures.</span>

Why does a deletion mutation usually cause more defects during protein synthesis than a point mutation?
BARSIC [14]
Answer: B

WHY?
Deletion mutation may cause a shift of base sequence, causing the reading frames for base sequence to change during translation. This may affect the type of amino acid it the original base sequence codes for, resulting in a change in amino acid sequence in the polypeptide translated. Therefore, affecting the whole protein itself. There may be wrong amino acids that prevents vital bonds like disulfide bridges to form, resulting in a huge change in 3 dimensional conformation of the protein. A point mutation may result in a gene sequence being edited. However, only the target sequence is being mutated. The rest of the gene sequences are left untouched. Therefore, the impact is localised. This ensures that even though a few wrong amino acids may be in the polyleptide, most of the bonds that are crucial for the correct 3 dimensional conformation is still present, therefore, lesser defects will be resulted due to point mutation as compared to deletion mutation.

When one gene is able to modify the effect of a second gene, the phenomenon is known as:
Ksju [112]

The phenomenon where one gene can modify the effect on the second gene is known as epistasis.

In genetics, epistasis is a phenomenon in which the effect of a gene mutation is determined by the presence or absence of mutations in one or more other genes, which are referred to as modifier genes. To put it another way, the genetic background in which the mutation appears determines its effect. It has long been acknowledged that epistasis, or interactions between genes, is fundamental to comprehending both the structure and function of genetic pathways and the evolutionary dynamics of complex genetic systems.
