Which is more infectious DNA VIRUS OR RNA VIRUS??

EXPLAIN​

Oncolytic virus immunotherapy utilizes natural or genetically altered DNA and RNA viruses to infect tumor cells and prevent them from initiating cancer immune evasion.1 DNA viruses such as adenoviruses and poxviruses are more likely to be double-stranded whereas most RNA viruses are single-stranded. Once the virus is injected into the host cell, it is targeted towards the nucleus allowing the viral DNA to integrate with the host cell's genome and hijack the host cell's polymerase enzymes to replicate the virus. DNA viruses like the poxvirus are packaged with their polymerase machinery so they can replicate in the host cytoplasm directly. RNA viruses infect cells by injecting RNA into the cytoplasm of the host cells to transcribe and replicate viral proteins. RNA viruses also include retroviruses which use reverse transcriptase to create DNA from RNA templates. This newly transcribed DNA can now be packaged and incorporated into the host genome so that subsequent cell division by the cell produces cells with the viral DNA integrated. Unlike DNA viruses which must always transcribe viral DNA into RNA to synthesize proteins, RNA can skip the transcription process. Furthermore, some RNA molecules can act as mRNA being translated directly into protein. This includes positive-strand RNA viruses which are distinct from negative-strand RNA viruses, which require the added step of mRNA transcription before they can be translated to proteins.

transcription is a process in which information is rewritten. it is something our cells must do, in a more specialized and narrowly defined way. in biology, transcription is the process of copying out the dna sequence of a gene in the similar alphabet of rna. it needs to happen in the nucleus because that's where the dna is. dna is always inside the nucleus unless the cell is dividing.

transcription is the first step in gene expression, which involves copying a gene's dna sequence to make an rna molecule. transcription is performed by rna polymerases. it has three stages: initiation, elongation, and termination. rna molecules must be processed after transcription in eukaryotes.

explanation:

long version:

the protein synthesis consists two processes which are, transcription and translation. transcription takes place in the nucleus. it uses dna as a template to make an rna molecule. rna then leaves the nucleus and goes to a ribosome in the cytoplasm, where translation occurs. transcription is the first part of the central dogma of molecular biology: dna → rna. it is the transfer of genetic instructions in dna to messenger rna (mrna). during transcription, a strand of mrna is made that is complementary to a strand of dna.  

these three stages are:

  initiation: in which   is the beginning of transcription.occuring when the enzyme rna polymerase binds to a region of a gene called the promoter. this signals the dna to unwind so the enzyme can ‘‘read’’ the bases in one of the dna strands. the enzyme is now ready to make a strand of mrna with a complementary sequence of bases.

    elongation: in which is the addition of nucleotides to the mrna strand. rna polymerase reads the unwound dna strand and builds the mrna molecule, using complementary base pairs. there is a brief time during this process when the newly formed rna is bound to the unwound dna. during this process, an adenine (a) in the dna binds to an uracil (u) in the rna.

    termination: in which is the ending of transcription, and occurs when rna polymerase crosses a stop (termination) sequence in the gene. the mrna strand is complete, and it detaches from dna.
