Chapter 24, Problem 1P
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).
Expert Solution & Answer
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
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.

In your answer, apply at least one ethical theory in support of your position.arrow_forwardYou aim to test the hypothesis that the Tbx4 and Tbx5 genes inhibit each other's expression during limb development. With access to chicken embryos and viruses capable of overexpressing Tbx4 and Tbx5, describe an experiment to investigate whether these genes suppress each other's expression in the limb buds. What results would you expect if they do repress each other? What results would you expect if they do not repress each other?arrow_forwardYou decide to delete Fgf4 and Fgf8 specifically in the limb bud. Explain why you would not knock out these genes in the entire embryo instead.arrow_forward

The technician suspected that they had may have made an error in the protocol – what is the most likely explanation? The cell membranes are more resistant than normal. An isotonic solution had been added instead of water. A solution of 0.1 M NaCl had been added instead of water. Not enough water had been added to the red blood cell pellet. The man had sickle-cell anaemia.arrow_forwardA sample of blood was taken from the above individual and prepared for haemoglobin analysis.
