Answer:

Explanation:

Deoxyribonucleic acid (DNA) is hereditary molecule found almost in every cell. Although it is very stable molecule but changes known as mutations may occur in this molecules. Deamination is also a type of mutation.

Deamination:

In deamination amino group is removed from Cytosine and produces uracil in DNA. This rate of conversion occurs about 100 bases per cell per day.

Sequence given in question is

... TACT... .

....ATGA...

After deamination the given sequence becomes

... TAUT... .

....ATAA...

Consider three molecules, named X, Y, and Z. When added to a beaker of water they undergo spontaneous reactions. When X is added
harina [27]

Both X and Z will increase in order.

Option D.

<h3><u>Explanation:</u></h3>

Here in the question we can see that all the three compounds X Y and Z are in equilibrium as they are put in a water beaker containing water. This phenomenon is Called chemical equilibrium when the substances that are isomers to each other actually forms in water and their relative concentration remains in a particular ratio according to their stability.

Here in the question, the solution contains X Y and Z in equilibrium. But if more Y is added in the solution, firstly the equilibrium constant for X and Y will get disrupted because X will get low in amount with respect to Y. So some Y will get converted to X. Similarly, when Z will also face the same problem and some Y will get converted to Z. Hence the amounts of both X and Y will increase along with Y.
