2 answers:
The melting point of DNA with 50% GC content = 104 °C
<h3>Further explanation</h3>DNA has a base pair of bonds between adenine and thymine and guanine and cytosine. These bonds are hydrogen bonds.
Three hydrogen bonds between guanine-cytosine and two hydrogen bonds adenine-thymine make denaturation of DNA by heating it requires greater heat energy.
The amount of guanine and cytosine in the DNA molecule (the GC content) is directly proportional to the melting point, the temperature at which DNA is denatured
If we plot between the melting point of DNA (y-axis) and the percentage of the GC content (x-axis) we will get a straight line equation
From the equation of the line (y = 0.5x + 79), with GC content 50%, we enter the GC value as x so we get the DNA melting point as y
y = 0.5.50 + 79
y = 104 °C
