Examples of polymers that contain repeating units known as nucleotides are:
How to calculate number of base pairs in a dna fragment
There are four main groups of organic macromolecules that are often present and are central to life in all lifeforms on Earth, from the tiniest bacterium to the largest sperm whale. Carbohydrates, lipids (or fats), proteins, and nucleic acids are all examples. All of the major macromolecule groups have one thing in common: they are massive polymers made up of small repeating monomer subunits. You learned about life’s polymers and their building block structures in Chapter 6, as shown in Figure 11.1. Remember that the nucleotide bases are the monomer units for building nucleic acids like DNA and RNA, while amino acids, sugar residues, and fatty acids or acetyl groups are the monomers for proteins, carbohydrates, and lipids.
The aim of this chapter is to provide an overview of the structure and function of these macromolecules. The major macromolecules are kept together by the same chemical linkages that you studied in Chapters 9 and 10, and they rely heavily on dehydration synthesis and hydrolysis for their formation and breakdown.
Introduction to biological molecules: monomers & polymers
Over the last decade, a great deal of knowledge about intrinsically conducting polymers, also known as “synthetic metals,” has been written. The idea that these new materials combine the physical and chemical properties of plastics with the electrical, mechanical, magnetic, and optical properties of metals or semiconductors is what piques people’s attention. (1) As a commercial material, poly (vinyl chloride) (PVC) is extremely useful. In terms of total global production volume, it is second only to polyolefins among thermoplastics. Despite its molecular instability against heat, which is far more pronounced than that of any of its major competitors, it has managed to achieve this status. This challenge has been solved to a large extent technologically, because otherwise, PVC use would never have achieved its current level. A number of patents filed separately in 1928 by Carbide and Carbon Chemical Corporation, Dupont, and IG Farben disclosed commercial interest in PVC.
Science for kids – what is dna ?
Nucleic acids, like many biological molecules, are polymers, which are long molecules made up of repeating units. The nucleotide is the repeating unit of nucleic acids. A five-carbon sugar, a nitrogen-containing base, and a phosphate group make up a nucleotide. Deoxyribonucleic acid (DNA) and ribonucleic acid (RNA), the two most common types of nucleic acids, have slightly different sugars in their nucleotides and a different collection of four bases that their nucleotides may include.
The ionization of the phosphate groups, which gives nucleic acids a strong net negative charge, is critical to electrophoresis. The charge to mass ratio of two different nucleic acid molecules would be very similar since each nucleotide is ionized.
Each nucleotide’s phosphate groups have a negative formal charge. The charge to mass ratio of different nucleic acid molecules is almost equal since each nucleotide has the same charge. Negatively charged nucleic acid molecules move toward the positive pole due to electric force.

The invention discloses methods for producing recombinant proteins with repeating units. Methods for producing degenerate polynucleotides encoding said recombinant proteins are also disclosed. Polypeptides and polynucleotides provided by the current invention’s methods are also disclosed.
This discovery is related to recombinant DNA technology, and more specifically, to methods for producing recombinant polynucleotide sequences and recombinant proteins with recurring sequences. The invention describes methods for producing polynucleotides and/or proteins with tandem repeats of short sequences in which complementary polynucleotides anneal and serve as primers, allowing the 3′ ends of complementary polynucleotides to be extended to generate long tandem repeat sequences.
The ability to generate recombinant proteins, especially therapeutic proteins, has been one of the most significant advances in molecular biology. Expression vectors can be used to introduce recombinant polynucleotides encoding the desired proteins into any number of host cells, which would then generate the desired protein. This method is particularly useful for the development of short peptides that do not require extensive post-translational modification for biological activity.
