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
DNA contains sugar deoxyribose, while RNA contains sugar ribose,
DNA is a double-stranded molecule, while RNA is a single-stranded molecule.
The State of California uses a mechanism known as "NOTS" to rehabilitate chronic violators of driving laws.
