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

We have the equation of the line as follows:
y = 0.5x + 79

We want to calculate the melting point (the y value) of DNA  with 50% gc content (the x value).
The gc content represents the value of x in the equation, so to calculate the melting point (y), we will simply substitute the x with 50 in the equation of the line as follows:
melting point = 0.5(50) + 79 = 25 + 79 = 104 degrees

Answer:

0.125

7.50/60=1.25

since there 60 minutes in one hour you would divide the hourly rate by 60.

what trigonometric expression can be used to find the value of x? replace a and b with the correct values.
Margaret [11]

The trigonometric function that can be used to find the value of x is 12 / tan ( 25 ) . The correct values of a and b will be 12 and 25 resp . .

Given :

A right angle triangle , one angle = 25 ° and side opposite given angle = 12 units .

Trigonometric Formula for Tan θ

tan θ = perpendicular / base , tan θ = ( sin θ / cos θ ) , tan θ = ( 1 / cot θ ) .

where θ = 25 , perpendicular = 12 , base = x .

Substituting values in above first formula ,

tan 25 = 12 / x

Therefore , x = 12 / tan ( 25 ) .

Hence , a = 12 and b = 25 .
