RNA - Wikipedia
Ribonucleic acid (RNA) is a polymeric molecule essential in various biological roles in coding, decoding, regulation and expression of genes.RNA and DNA are nucleic acids, and, along with lipids, proteins and carbohydrates, constitute the four major macromolecules essential for all known forms of life.Like DNA, RNA is assembled as a chain of nucleotides, but unlike DNA it is more often found ...
Ribonucleic acid supplement | iHealth Directory
Ribonucleic acid supplement. If you’ve taken any type of science class, you are familiar with (at least the terms) DNA and RNA. For simplicity’s sake, let’s review: DNA and RNA are nucleic acids that are found in the cytoplasm of every single cell in the body.
Small interfering RNA - Wikipedia
Small interfering RNA (siRNA), sometimes known as short interfering RNA or silencing RNA, is a class of double-stranded RNA molecules, 20-25 base pairs in length, similar to miRNA, and operating within the RNA interference (RNAi) pathway. It interferes with the expression of specific genes with complementary nucleotide sequences by degrading mRNA after transcription, preventing translation
Rna | Definition of Rna at Dictionary.com
Rna definition, ribonucleic acid: any of a class of single-stranded molecules transcribed from DNA in the cell nucleus or in the mitochondrion or chloroplast, containing along the strand a linear sequence of nucleotide bases that is complementary to the DNA strand from which it is transcribed: the composition of the RNA molecule is identical with that of DNA except for the substitution of the ...

Polycistronic mRNA Definition - Protein Synthesis
Polycistronic vs Monocistronic. Polycistronic mRNA refers to a messenger RNA which encodes two or more proteins. Polycistronic messenger RNAs participates in the process of protein synthesis (translation) in prokaryotes. Many bacterial mRNAs are fully functional in their primary composition transcripts meaning that they do not require any posttranscriptional modifications.
