Making DNA models can be informative, fun, and in this case tasty. Here you will learn how to construct aDNA modelusing candy. But first, what isDNA? DNA, likeRNA, is a type of macromolecule known as anucleic acidthat contains the genetic information for the reproduction of life. DNA i...
method of producing by the method according to recombinant proteins present in the subunits of two or more in nature; generally, obtained by ligation of DNA fragments of discrete two or more than Amplification of any chimeric DNA molecules are, and can be applied to the expression to be ...

How does DNA code for proteins in a cell? What is the role of DNA in transmitting genetic information? How does the structure of DNA allow cells to replicate? How is genetic information encoded in a DNA molecule? How does the structure of DNA determine our characteristics?
Students build three-dimensional models in order to understand the structure of DNA. A flattened DNA molecule looks like a ladder. The legs of the ladder consist of an alternating pattern of ribose sugars and phosphates. The rungs of the ladder consist of nucleotide base pairs. A single rung...
Watching DNA polymerase η make a phosphodiester bond. Nature 487, 196–201 (2012). A breakthrough in studying phosphodiester bond formation was achieved with the use of a revised method of time-resolved X-ray crystallography. Monitoring this reaction revealed the role of a third metal ion in ...
One strand of the DNA molecule runs 5' to 3'. The other strand runs 3' to 5'. This makes the two strands what? What molecules make up the rungs of the DNA structure? How many nucleotides define one codon for one amino acid?
Germ cells are the only cells in the body capable of giving rise to a new organism, and this totipotency hinges on their ability to assemble membraneless germ granules. These specialized RNA and protein complexes are hallmarks of germ cells throughout their life cycle: as embryonic germ granules...
Where Do We Get Our DNA? Deoxyribonucleic acid, or DNA, is a molecule containing instructions on how to make a living organism. Its structure and sequence instruct the cell on how to make proteins, which go on to carry out important functions of a cell. Many cells form tissues, many tiss...
DNA is a molecule like a recipe for life and holds all the information your body needs to function. Pretty crazy! Even more amazing is that just a teeny, tiny percent of our DNA actually makes us unique. You may also be surprised to know that some of the DNA in strawberries is also ...
