    Explanation:
    • CRISPR-Cas9 technology behaves like a cut-and-paste mechanism on DNA strands that contain genetic information. A DNA strand, when broken, has a natural tendency to repair itself. Scientists intervene during this auto-repair process, supplying the desired sequence of genetic codes that binds itself with the broken DNA strand
    • Recently, Emmanuelle Charpentier of France and Jennifer A Doudna of the USA have been awarded the 2020 Nobel Prize in Chemistry for developing CRISPR/Cas9 genetic scissors, one of gene technology’s sharpest tools. It is for the first time a Nobel science prize has gone to a women-only team.

    Hence both statements are correct.
