All genes regardless of the type of organism are made of the same basic building blocks called nucleic acids. These nucleic acids combine to form long strands know as deoxyribonucleic acid (DNA). There are four different types of DNA adenine (A), cytosine (C), thymine (T), Guanine (G) ...
Lipids, saccharides, and amino acids may combine with molecules of its own class to form either polymers (molecules formed by successively covalently attaching smaller molecules), such as polysaccharides and proteins, or supramolecular assemblies (organized arrangements of molecules that are in contact ...
biomolecule, also called biological molecule, any of numerous substances that are producedby cells and living organisms. Biomolecules have a wide range of sizes and structures and perform a vast array of functions. The four major types of biomolecules are carbohydrates, lipids, nucleic acids, and ...
Proteins form when monomers called amino acids combine. Amino acids contain a carboxylic and an amino group on either end of the molecule. The carboxylic group of one amino acid combines with the amino group of another, forming a peptide bond. Several amino acids join together to form polypepti...
Sometimes, the reactions are multiplexed to combine in one reaction the analysis of several DNA or RNA targets, and the nucleic acid processing or analysis may involve multiplexing of two or three enzymatic processes in one reaction. Furthermore, DNA and RNA enzymatic reactions frequently utilize ...
First, several challenges remain in the use of immunotherapy for cancer, such as poor immune cell infiltration, insufficient co-activation signals, and negative regulation of immune checkpoints. Combine soluble immune checkpoints with immunotherapy might improve anti-tumor immunity. Recent studies mostly...
It is also conceivable to combine the embodiments outlined in FIG. 1 and immobilize both the target nucleic acid molecule and the nucleic acid polymerizing enzyme proximate to each other. The sequencing process of the present invention can be used to determine the sequence of any nucleic acid ...
Quantum dots are nano-sized chunks of crystal, each containing hundreds to thousands of semiconductoratoms. When viewed through an electron microscope they look like dots. As with real atoms, when you combine artificial atoms together, they create a new (artificial) molecule with unique properties ...
