Concept explainers

It is an organic molecule made up of three basic components- a nitrogenous base, phosphate,and pentose sugar. The nucleotides are important for metabolic reactions andthe formation of DNA (deoxyribonucleic acid) and RNA (ribonucleic acid).

Nucleic Acids

Nucleic acids are essential biomolecules present in prokaryotic and eukaryotic cells and viruses. They carry the genetic information for the synthesis of proteins and cellular replication. The nucleic acids are of two types: deoxyribonucleic acid (DNA) a…

Textbook Question

Chapter 1, Problem 6P

RNA shares with proteins the ability to fold into complex three-dimensional shapes. As a result, RNA molecules can, like protein molecules, catalyze biochemical reactions (that is, both kinds of molecules can act as enzymes, or biological catalysts). These statements are not true of DNA. Why can some RNA molecules act as enzymes whereas DNA molecules cannot? (Hint: Most RNA molecules consist of a single strand of nucleotides while most DNA molecules are double helixes made of two strands of nucleotides.)

PCBs and River Otters: Otters in Washington State’s Green-Duwamish River have high levels of polychlorinated biphenyls (PCBs) in their livers. PCBs can bind to the estrogen receptors in animals and disrupt the endocrine system of these otters. The PCBs seem to increase the estrogen to androgen ratio, skewing the ratio toward too much estrogen. How would increased estrogen affect the river otter population? Based on your reading of the materials in this unit, what factors can affect fertility in humans? Explain how each of the factors affecting human fertility that you described can disrupt the human endocrine system to affect reproduction.
