Answer:
CRISPR Used To Edit Genes Inside A Patient With A Rare Form Of Blindness
and what CRISPR is is s a family of DNA sequences found in the genomes of prokaryotic organisms such as bacteria and archaea.[2] These sequences are derived from DNA fragments of bacteriophages that had previously infected the prokaryote. They are used to detect and destroy DNA from similar bacteriophages during subsequent infections. Hence these sequences play a key role in the antiviral (i.e. anti-phage) defense system of prokaryotes.[2]

The CRISPR-Cas system is a prokaryotic immune system that confers resistance to foreign genetic elements such as those present within plasmids and phages[4][5][6] and provides a form of acquired immunity. RNA harboring the spacer sequence helps Cas (CRISPR-associated) proteins recognize and cut foreign pathogenic DNA. Other RNA-guided Cas proteins cut foreign RNA.[7] CRISPR are found in approximately 50% of sequenced bacterial genomes and nearly 90% of sequenced archaea.

One of the most common conflict between human and machines that have arisen in the past and is still present up to today is the substitution of the machine to the jobs that could have been the source of income for the human beings.
Early diagnosis of childhood cancer is often difficult because the signs and symptoms are SIMILAR TO THOSE OF OTHER CHILDHOOD DISEASES.
Doctors generally find it difficult to diagnosis cancer i children because the accompany symptoms for the disease is quite similar to those of other diseases that children experience. Cancer in children usually occur very rapidly and its diagnosis in most cases typically occur at the late stage.
Shrublands are a unique biome named for the many aromatic, semi-woody shrubs that thrive there. For instance, xeric, or desert scrublands, are hot and dry, with little rainfall.
