mediumThe function t gives the estimated melting temperature, in degrees Celsius, of a DNA molecule as a function of the percent of guanine-cytosine (GC) content, x, in the DNA molecule. The graph of y=t(x) is shown. According to the graph, which of the following statements is NOT true?
A
For each increase of x by 1, t(x) increases by approximately 52.
B
A DNA molecule with a GC content of 0% has an estimated melting temperature between 60∘C and 65∘C.
C
A DNA molecule with a GC content of 95% has an estimated melting temperature between 100∘C and 105∘C.
D
A DNA molecule with a GC content of 98% has an estimated melting temperature between 80∘C and 90∘C.
