Answer:
CRISPR can also be used to make precise changes such as replacing faulty genes – true genome editing – but this is far more difficult. Customised Cas proteins have been created that do not cut DNA or alter it in any way, but merely turn genes on or off: CRISPRa and CRISPRi respectively.

Btw, i think you meant meteorologists.
Answer: "Decreasing the salt concentration of the solution lowers DNA's melting point (Tm)" is not a true statement
Explanation:
Increasing salt concentration would lower the DNA's melting point (Tm), not otherwise.
For instance:
- In 8M urea (8M means 8 Moles per dm3), Tm is decreased by nearly 20°C.
- 95% formamide at room temperature would completely denature the double stranded DNA.
Thus, higher concentration of salts like urea or formamide lowers Tm, not otherwise
