MCQ
The following ratio is generally constant for a given species:
- A
$\frac{ \text{T + C} }{ \text{G + A} }$
- B
$\frac{ \text{G + C} }{ \text{A + T} }$
- C
$\frac{ \text{A + C} }{ \text{T + G} }$
- D
$\frac{ \text{A + G} }{ \text{C + T} }$
$\frac{ \text{T + C} }{ \text{G + A} }$
$\frac{ \text{G + C} }{ \text{A + T} }$
$\frac{ \text{A + C} }{ \text{T + G} }$
$\frac{ \text{A + G} }{ \text{C + T} }$
Explanation:
The ratio of the sum of the adenine plus thymine bases to the sum of the guanine plus cytosine bases in a DNA molecule is called as $\frac{ \text{G + C} }{ \text{A + T} }$ ratio. Generally, $\frac{ \text{G + C} }{ \text{A + T} }$ ratio is constant for a given species. This ratio differs from species to species. However, it is constant for a given species. Species living in high temperature have high $\frac{ \text{G + C} }{ \text{A + T} }$ ratio as it gives stability due to triple hydrogen bond between Guanine and Cytosine.
