Summary
Experiments using optical and magnetic tweezers reveal how stretching individual DNA molecules affects their structure. This research also examines how DNA polymerase synthesizes complementary chains when the DNA template is stretched.
Area of Science:
- Biophysics
- Molecular Biology
- Genetics
Context:
- Single-molecule experiments represent a novel trend in biophysical studies.
- Optical and magnetic tweezers allow precise force application to individual DNA molecules.
Purpose:
- To assess the structural transitions of the DNA double helix under applied external force.
- To investigate the impact of DNA stretching on DNA polymerase activity.
Summary:
- Experiments utilized optical and magnetic tweezers to apply force to single DNA molecules, observing structural changes in the DNA double helix.
- The study presents recent data on how the rate of DNA synthesis by DNA polymerase is influenced by the stretching of the DNA template.
Impact:

The DNA Helix
Overview
DNA as a Genetic Template
Two structural features of the DNA molecule provide a basis for the mechanisms of heredity: the four nucleotide bases and its double-stranded nature. The Watson-Crick model of double-helical DNA structure, proposed in 1952, drew heavily upon the X-ray crystallography work of researchers Rosalind Franklin and Maurice Wilkins. Watson, Crick, and Wilkins jointly received the Nobel Prize in Physiology or Medicine for their work in 1962. Franklin was, controversially, excluded from the prize for...
DNA Topoisomerases
Topoisomerases are enzymes that relax overwound DNA molecules during various cell processes, including DNA replication and transcription. These enzymes regulate positive and negative DNA supercoiling without changing the nucleotide sequence. DNA overwinding in a clockwise direction results in positively supercoiled DNA, whereas underwinding in a counterclockwise direction produces negatively supercoiled DNA.

The DNA Helix
Deoxyribonucleic acid, or DNA, is the genetic material responsible for passing traits from generation to generation in all organisms and most viruses. DNA is composed of two strands of nucleotides that wind around each other to form a spring-like structure called a double helix. However, the double helix is not perfectly symmetrical. Instead, there are regularly occurring grooves in the structure. The major groove occurs where the sugar-phosphate backbones are relatively far apart. This space...

Nucleic Acid Structure
The pentose sugar in DNA is deoxyribose, while in RNA the pentose sugar is ribose. The difference between the sugars is the presence of the hydroxyl group on the ribose's second carbon and a hydrogen on the deoxyribose's second carbon. The phosphate residue attaches to the hydroxyl group of the 5′ carbon of one sugar and the hydroxyl group of the 3′ carbon of the sugar of the next nucleotide, which forms a 5′ to 3′ phosphodiester linkage.
