Answer:
In a series of experiments using human cancer cell lines, scientists at Johns Hopkins Medicine say they have successfully used light as a trigger to make precise cuts in genomic material rapidly, using a molecular scalpel known as CRISPR, and observe how specialized cell proteins repair the exact spot where the gene was cut.
Results of the experiments, published June 11 in Science, not only reveal new details about the DNA repair process, but also are likely, the researchers say, to speed up and aid understanding of the DNA activity that typically causes aging and many cancers.
Explanation:
Xylem vessel, that's the one that transport water and mineral ions up to the plant.
<span>the lacrimal bone helps form the nasolacrimal canal necessary for tear translocation. A depression on the anterior inferior portion of the bone, the lacrimal fossa, houses the membranous lacrimal sac. Tears or lacrimal fluid, from the lacrimal glands, collect in this sac during excessive lacrimation. The fluid then flows through the nasolacrimal duct and into the nasopharynx. This drainage results in what is commonly referred to a runny nose during excessive crying or tear production. Injury or fracture of the lacrimal bone can result in posttraumatic obstruction of the lacrimal pathways</span>
The role is speeding up chemical reactions
Hi friend
