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.

7. Adenine (A), Guanine, Cytosine and Thymine are the four nitrogenous bases in DNA.

8. In DNA Cytosine always forms hydrogen bonds with guanine.

9. The sequence of nucleotides carries the genetic information of an organism.

10. The process of replication produces a new copy of an organism's genetic information which is passed on to a new cell.

11. The double-coiled shape of DNA is called a double helix

Explanation:

There are four nitrogenous bases in the DNA of an organism. Two of the bases are pyrimidines eg: Thymine and cytosine while 2 of the bases are purine  bases namely adenine and guanine. The purine of one strand forms a hydrogen bond with pyrimidine of the parallel strand of DNA.

The bases are present in nucleoplasm as dNMPs and in DNA they are present as dNTPs (deoxyribonucleotide triphosphate). During replication, these dNMPS keeps on bonding with other dNMPs in the presence of ATP and as DNA Polymerase, ligase topoisomerase etc. These nucleotides form the DNA strands and they are responsible for coding proteins. The sequence of DNA is also termed as gene.

The double helix structure of DNA was given by Watson and Crick. Each strand has an alternative backbone of sugar and phosphate group. The four bases bonds with glycosidic and phosphodiester bonds with sugar and phosphoric acid.
