Which of the following is not true regarding the denaturation and reannealing of double-stranded DNA molecules? Which of the fol

lowing is not true regarding the denaturation and reannealing of double-stranded DNA molecules? Decreasing the salt concentration of the solution lowers DNA's melting point (Tm). Increasing the G-C content of DNA raises its melting point (Tm). Single-stranded DNAs can only anneal to one another if they are 100% identical in nucleotide sequence. Melting point (Tm) is the temperature at which the DNA is one-half double-stranded and one-half single-stranded. DNA is more likely to denature when exposed to a high pH.

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

Energy is the ability to do work which is stored in the body inform of ATP (adenosine triphosphate). ATP is comprised of a base Adenine, a ribose sugar (5 carbon sugar) and three phosphate groups. when a bond is broken energy is released and when a bond is formed energy is stored. ATP is used by cells as a source of energy such that ATP can easily release or store energy by breaking the chemical bonds and reforming the bonds between its phosphate group. The correct answer is c, phosphate- phosphate bond
