RNA hybrid in biosynthesis is a double-stranded polynucleic acid in which one strand is DNA and the other strand is the complementary RNA; formed during transcription and during multiplication of oncogenic RNA viruses. One of several forms that can be assumed by a double helix. A-DNA is stable in dehydrated conditions.
Double-Stranded Polynucleic Acids
A nuclease (a nucleate oligonucleotidohydrolase) that forms oligonucleotides ending in 5'-phosphates from RNA and DNA; hydrolyzes both double-stranded and single-stranded polynucleic acids. This form is less common than the dominant form found under physiological conditions -- beta-dna.
RNA hybrid is a double-stranded polynucleic acids in which one strand is DNA and the other strand is the complementary RNA; formed during transcription and during multiplication of oncogenic RNA viruses.This form is also assumed by DNA-RNA hybrid helices and by regions of double-stranded RNA. It is a right-handed helix and is a more compact form than beta-DNA.
