A gene editing technology called CRISPR-Cas9 uses cellular machinery to change the cell's genetic material. How might this techn
ology be useful in treating diseases like cancer? A. CRISPR-Cas9 could act as an antioxidant in a person's cells, removing toxins that might otherwise damage DNA. B. CRISPR-Cas9 could remove from patients the genetic mutations that cause a specific cancer before the cancer begins. C. CRISPR-Cas9 could remove any DNA damage caused by smoking. D. CRISPR-Cas9 could be a substitute for chemotherapy
CRISPR-Cas9 is a gene-editing mechanism that is harnessed from bacteria’s immune system used to cut apart foreign genetic material such as that of bacteriophages. CRISPR-Ca9 has a guide sequence that is used to identify the target sequence. The Cas9 enzyme cuts this target DNA and is replaced with the required piece.
In cancer treatment, the mutated DNA can be replaced, this way, with the wild type.
Vitamin a stays accumulated in your system and so only a concern if Greg is vitamin a deficient but he is probably getting other sources of vit a in his diet as well
