which recent discovery led to a new understanding of how genetic mutations increase the risk of cancer?\ndouble helix structure of dna\nbrca1 and brca2 genes\nnucleic acid monomers\nformation of tumor suppressor proteins
Answer
Brief Explanations:
- The double helix structure of DNA was discovered in 1953. While fundamental to genetics, it's not a recent discovery relevant to the question about recent understanding of genetic mutations and cancer risk.
- Nucleic acid monomers are basic units of nucleic acids (like DNA and RNA). Knowledge of them is foundational but not a recent discovery tied to the specific context of genetic mutations and cancer risk in the question.
- The formation of tumor - suppressor proteins is a general biological process. It doesn't represent a recent discovery that specifically led to a new understanding of how genetic mutations increase cancer risk.
- BRCA1 and BRCA2 genes were more recently (in the context of the other options) associated with cancer risk. Mutations in these genes are known to significantly increase the risk of breast, ovarian, and other cancers. This discovery provided new insights into how specific genetic mutations contribute to cancer risk.
Answer:
BRCA1 and BRCA2 genes
