Question

explain why people who inherit one mutated allele of the BRCA1 gene have higher likelihood of developing cancer

Answer 1

Explanation:

The cancer risk caused by BRCA1 and BRCA2 mutations are inherited in a dominant fashion even though usually only one mutated allele is directly inherited. This is because people with the mutation are likely to acquire a second mutation, leading to dominant expression of the cancer.

Answer 2

The reason why people who inherit one mutated allele of the BRC A1 gene have higher likelihood of developing cancer is:

● The genes BRCA1 and BRCA2 are engaged with cell development, cell division, and the fix of harm to DNA.

● Transformations or mutations in the BRCA genes can cause DNA harm in cells to go unrepaired, which builds the opportunity that an individual will build up certain sorts of disease like cancer

● A BRCA transformation happens when the DNA that makes up the genes gets harmed here and there.

● At the point when a BRCA gene is transformed, it might never again be successful at fixing broken DNA and assisting with forestalling bosom malignant growth.
