Molecular breeding is the application of molecular biology tools, often in plant breeding [1] [2] and animal breeding. [3] [4] In the broad sense, molecular breeding can be defined as the use of genetic manipulation performed at the level of DNA to improve traits of interest in plants and animals, and it may also include genetic engineering or gene manipulation, molecular marker-assisted ...
DNA shuffling by molecular breeding was first reported in 1994 by Willem P.C. Stemmer. [1] [7] He started by fragmenting the β-lactamase gene that had been amplified with the polymerase chain reaction (PCR) by using DNase I, which randomly cleaves DNA.
Plant breeding can be performed using many different techniques, ranging from the selection of the most desirable plants for propagation, to methods that make use of knowledge of genetics and chromosomes, to more complex molecular techniques. Genes in a plant are what determine what type of qualitative or quantitative traits it will have.

[1]: 1 Various techniques were developed to aid in breeding and selection. Hybridization was one way rapid changes in an organism's genetic makeup could be introduced. Crop hybridization most likely first occurred when humans began growing genetically distinct individuals of related species in close proximity.
America’s top investors have achieved double-digit returns for years, sometimes decades. Following these top investors is a great strategy for two reasons.
The molecular structure of DNA. Bases pair through the arrangement of hydrogen bonding between the strands. The molecular basis for genes is deoxyribonucleic acid (DNA). DNA is composed of deoxyribose (sugar molecule), a phosphate group, and a base (amine group). There are four types of bases: adenine (A), cytosine (C), guanine (G), and thymine ...
