Summary Introduction

To determine:

The chemical composition of the genetic material.

Introduction:

The genetic information stored in the cell organelles (mitochondria and nuclei) that decides the development of an organism is called genetic material. The genetic material is also called DNA (deoxyribonucleic acid).

Explanation of Solution

The DNA molecule is highly coiled and incorporated in the nucleus of the eukaryotic cells and in the prokaryotic cells. The DNA floats in the cytoplasm in the form of a circle. The subunit of the DNA molecule is called nucleotide.

The nucleotide consists of a sugar molecule, attached by a phosphate group, which further is attached to a base. The four bases present in a DNA molecule are Adenine (A), Guanine (G), Cytosine (C), and Thymine (T).

The purines are the major bases present in the DNA, which includes Adenine and Guanine. The pyrimidines are the bases present in the DNA, which includes Cytosine and Thymine. The number of the bases (pyrimidine) is equal to the number of bases (purine).

Also, the adenine is equal to the thymine in number and guanine is equal to the cytosine in number. The sugar molecule present in the DNA molecule is a deoxyribose sugar (five-carbon sugar). The sugar molecule is attached to the nitrogenous base and that is called nucleoside. In the DNA molecule, the bases are assembled on each other, thus forming a helical structure.

Conclusion

The genetic material is composed of many monomers, called nucleotides. The nucleotide consists of nitrogenous bases, deoxyribose sugar, and a phosphate group. The nucleotides are arranged to form a long chain of genetic material known as DNA.
