Question

Prompt

The 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?

For each increase of

x

1

t (x)

increases by approximately

\frac{2}{5}

A DNA molecule with a GC content of

0%

has an estimated melting temperature between

6 0^{\circ} C

and

6 5^{\circ} C

A DNA molecule with a GC content of

95%

has an estimated melting temperature between

10 0^{\circ} C

and

10 5^{\circ} C

A DNA molecule with a GC content of

98%

has an estimated melting temperature between

8 0^{\circ} C

and

9 0^{\circ} C
