Double stranded rna vs dna- A DNA or RNA vaccine has the same goal as traditional vaccines, but they work slightly differently Instead of injecting a weakened form of a virus or bacteria into the body, DNA and RNA vaccines use part of the virus' own genes to stimulate an immune responseDoublestranded DNA and RNA, and DNA/RNA hybrids form naturally in cells between two nucleic acid strands containing complementary sequences However, these doublestranded nucleic acid structures need to be separated for DNA replication, RNA transcription, RNA processing, and DNA

2 DNA vs RNA Doublestranded Sugar = deoxyribose Thymine (no Uracil) Stays in nucleus One type Same copy in the cell all the time Singlestranded Sugar = ribose Uracil (instead of Thymine) In nucleus & cytoplasm 3 types mRNA, tRNA, rRNA Disposable copies Gene is made up of DNA or RNA;SsDNA vs dsDNA – A Comparison Table The DNA molecules are not always double stranded helical structures, sometimes they occur in single stranded form called ssDNA In 1959 Robert Sinsheimer discovered a unique bacteriophage called φX 174 (which infect Escherichia coli) with single stranded DNA as its genetic material

Genetics is the study of inheritance The genetic makeup of an organism is transmitted via DNA replication The DNA can either be singlestranded or doublestranded The core difference between singlestranded DNA and doublestranded DNA is that singlestranded DNA has a star shape while doublestranded DNA has a linear formDoubleStranded RNA Production of doublestranded RNA (dsRNA) is a part of the coxsackievirus replication cycle It has been shown that dsRNA is able to directly stimulate a dsRNctivated protein kinase (PKR) A major substrate of PKR is the α subunit of the eukaryotic translation initiation factor 2 (eIF2α)There are two differences that distinguish DNA from RNA (a) RNA contains the sugar ribose, while DNA contains the slightly different sugar deoxyribose (a type of ribose that lacks one oxygen atom), and (b) RNA has the nucleobase uracil while DNA contains thymine

And (3) RNA contains uracil in place of thymineRNA is different from DNA is three ways (1) the sugar in RNA is ribose not dioxyribose; The RNA controls the formation of proteins needed by the virus to coat the viral DNA This coating of viral DNA is known as a capsid The capsids accumulate inside the cell until the cell reaches capacity and bursts open, releasing

DNA stands for deoxyribonucleic acid, which is a molecule that contains most of the genetic instructions of the body DNA viruses can be generally divided into three categories adenoviruses, poxviruses, and inoviruses Once the doublestranded DNA is injected into the host cell, it will enter the nucleus of the cell, where the viral DNA can possibly be integrated with the host cell's DNAQuestion 4 SURVEY 45 seconds Q Watson and Crick were the first to suggest that DNA is _____ answer choices a short molecule the shape of a double helix aAfter all, RNA is supposed to be a copy of DNA However, there are a few differences between the two molecules The biggest difference is in their shape DNA is a twostranded molecule in the form of a double helix RNA, on the other hand, is a singlestranded molecule

DNA molecules are much more stable because they are double stranded throughout their length and enzymes are normally present in the nucleus to repair damage to DNA;Another major difference between DNA and RNA is that DNA is usually found in a doublestranded form in cells, while RNA is typically found in a singlestranded form The lack of a paired strand allows RNA to fold into complex, threedimensional structures while DNA can not do this RNA folding is typically mediated by the same type interactions DNA DNA is doublestranded and it exhibits a doublehelix structure RNA RNA is usually singlestrand, sometimes it forms secondary and tertiary structures Preferred Conformation DNA DNA prefers Bform RNA RNA prefers Aform Function DNA DNA carries the genetic information necessary for the development, functioning, and reproduction
