I would say its between A and D, Hope it helps.
Answer:
- They are made of denser objects, which can condense at relatively high temperatures;
- They are made of heavier elements, which have a stronger gravitational attraction to the Sun;
<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
Answer:
Autoregulation
Explanation:
When the activities of a cell, tissue, organ, or system change automatically due to environmental variation, the homeostatic mechanism that operates is called autoregulation.
Autoregulation is a method of controlling the local blood circulation. It is characterized as an organ's inherent capacity to sustain a standard blood flow, given changes in the pressure of the perfusion.
