Double stranded dna vs single stranded rna
Double stranded dna vs single stranded rna-RNA's sugar is deoxyribose DNA is single stranded; DNA double helix means that the twostranded structure of DNA structure is common knowledge, RNA's single stranded format is not as well known RNA can form into doublestranded structures, such as during translation, when mRNA and tRNA molecules pair

Answer (1 of 4) Major differences are there between double stranded DNA and single stranded DNA DsDNA usually found in linear form, while ssDNA is star shaped form DsDNA is more stable, hence found in almost all organisms, while ssDNA is found merely in few viruses According to Chargauf rule This indicates that the doublestranded RNA structure is required in addition to the 3′ DNA extension to protect the siRNA moiety from attack Addition of the DNA extension to singlestranded siRNA did result in less degradation, however, than for unmodified singlestranded siRNA (Figure 5e)Rotaviruses are double stranded RNA viruses comprising a genus within the family Reoviridae The mature virus particles are triple layered, approximately 70 nm in diameter, and possess icosahedral symmetry The rotavirus genome consists of 11 segments of doublestranded RNA that code for 6 structural viral proteins and 6 nonstructural proteins

Unlike doublestranded DNA, RNA is a singlestranded molecule in many of its biological roles and consists of much shorter chains of nucleotides However, a single RNA molecule can, by complementary base pairing, form intrastrand double helixes, as in tRNARNA is transcribed from DNA by enzymes called RNA polymerases and further processed by other enzymes But there are some exceptions where RNA is double stranded and DNA is single stranded Examples of double stranded RNA are reovirus, retrovirus, hepatitisB virus etc and the single stranded DNA is present in phage FX174 and parvovirusDouble Stranded DNA 00 50 Single Stranded RNA 0025 40 Single Stranded DNA 0027 33 While direct concentration of nucleic acids is fairly accurate, there can be dramatic variation in direct protein concentration results measured at OD280
