A full moon appears white to us on earth because it A) emits white light B) reflects the light from earth C) reflects the light
mars1129 [50]

Answer:

C) Reflects the light from the sun

Explanation:

Moon does not emit its own light. The moonlight is primarily the sunlight that is being reflected form the surface of moon. The moon is actually quite black so only a little amount of sunlight is reflected back.

We see colour due to the presence of cones in our retina. When we look at the moon, the light coming from moon does not have enough intensity to excite or cone cells and thus only rod cell are get excited. As the rods can't sense colours so the moon appears white.

<h2>CRISPR/Cas9</h2>

Explanation:

CRISPR can be used to reintroduce dystrophin back into the KO mouse

  • CRISPR stands for Clustered Regularly Interspaced Short Palindromic Repeats and is used to for gene editing
  • CRISPR/Cas-mediated genome editing has been shown to permanently correct DMD mutations and restore dystrophin function in mouse models
  • Germline editing by injecting zygotes with CRISPR/Cas9 editing component was first done in mdx mice by correcting the mutated exon 23
  • Postnatal editing of mdx mice was then achieved using recombinant adeno-associated virus to deliver CRISPR/Cas9 genome editing components and correct the dystrophin gene by skipping or deleting the mutated exon 23 in vivo
  • Germline and postnatal CRISPR/Cas9 editing approaches both successfully restored dystrophin function in the mice and same technique can be used for KO mouse model
