However and RNA
However, because eukaryotic DNA has introns, and prokaryotes lack the machinery for removing introns from transcribed RNA, to make this approach work, all intron sequences must be removed from eukaryotic DNA prior to transferring it into the host.
However, different types of introns were identified through the examination of intron structure by DNA sequence analysis, together with genetic and biochemical analysis of RNA splicing reactions.
However, it is now well-established that some introns themselves encode specific proteins or can be further processed after splicing to generate noncoding RNA molecules.
However, the HIV-encoded reverse transcriptase has own ribonuclease activity that degrades the viral RNA during the synthesis of cDNA, as well as DNA-dependent DNA polymerase activity that copies the sense cDNA strand into an antisense DNA to form a double-stranded DNA intermediate.
However, it is notable that, in ribosomal RNA, many of the post-transcriptional modifications occur in highly functional regions, such as the peptidyl transferase center and the subunit interface, implying that they are important for normal function.
However, the enzyme discovered by Ochoa ( polynucleotide phosphorylase ) was later shown to be responsible for RNA degradation, not RNA synthesis.
However RNA is less stable.
However, retroviruses function differently-their RNA is reverse-transcribed into DNA, which is integrated into the host cell's genome ( when it becomes a provirus ), and then undergoes the usual transcription and translational processes to express the genes carried by the virus.
