RNA Genetics

With over 20 years experience in custom synthesis for the biomedical research communities, BSI has developed the expertise to deliver custom synthesized RNA with quality that meets all your RNAi, siRNA, shRNA and other RNA projects.

Ribonucleic acid (RNA)

Ribonucleic acid (RNA) is a nucleic acid and consists of a long chain of nucleotide units. Each nucleotide consists of a nitrogenous base, a ribose sugar, and a phosphate. RNA is very similar to DNA, but differs in a few important structural details: in the cell RNA is usually single stranded, while DNA is usually double stranded.

Unmodified RNA

Over 100 different chemical types of modifications have been identified in thousands of sites in tRNAs, rRNAs, mRNAs, small nuclear RNAs, and other RNAs. Some modifications are highly conserved, while others are more specialized.


Genetics (from Ancient Greek γενετικός genetikos, “genitive” and that from γένεσις genesis, “origin”), a discipline of biology, is the science of heredity and variation in living organisms. The fact that living things inherit traits from their parents has been used since prehistoric times to improve crop plants and animals through selective breeding. However, the modern science of genetics, which seeks to understand the process of inheritance, only began with the work of Gregor Mendel in the mid-nineteenth century.

Hi all,

Ribonucleic acid or RNA is one of the three major macromolecules along with DNA and proteins that are essential for all known forms of life. Some RNA molecules play an active role in cells by catalyzing biological reactions, controlling gene expression and communicating responses to cellular signals. Thanks!
