A silent mutation. This is when the new codon will work just as well as the old one without changing the amino acid shape.
Sporadic cancer is cancer by chance, there is no relative with the same type of cancer. Familial Cancer, on the other hand, is a combination of genetic and environmental factors. Hereditary cancer, moreover, happens when a defective gene is passed from parent to child. Breast and ovarian cancer fall under hereditary cancer though it does not mean that if either of the parents have these types of cancer, the offspring will definitely acquire it. If either of the parents has the defective gene for breast or ovarian cancer, the offspring has higher chances of having the aforementioned cancer.
Answer:
The correct answer will be option-C
Explanation:
The beta-pleated sheet is the secondary structure formed by multiple strands of polypeptide in antiparallel, parallel or mixed direction.
The antiparallel strands of the polypeptides are connected to each other through hydrogen bonding between the CO group of one strand to the NH group of another strand.
Since hydrogen bonds stabilize the two strands of polypeptides in beta-pleated sheet, therefore, the hydrogen bond is the correct answer.
