The chemical stability of abasic RNA compared to abasic DNA


The protein synthesis occurs by means of transcrition (in the nucleus: production of RNA with nitrogenous bases that are complementary to one of the ; thus DNA -> RNA) and translation (in polyribosomes and the both located in the cytoplasm: RNA codes -> specific chains of aminoacids, i.e.

Class III (e.g. paramyxoviruses, rhabdoviruses.) Thegenome is of -ve polarity to the messenger. A virion RNA-dependentRNA transcriptase first transcribes the genomes into separatemonocistronic messengers initiating at a single promoter. Thetranscriptase stops and restarts at each juncture betweendifferent genes.

DNA, Replication, and Protein Synthesis

F. Hepadnaviruses - Hepatitis B virus employs reversetranscription for replication. The genome consists of a partiallydouble-stranded circular DNA with a complete negative strand andan incomplete positive strand. Upon entering the cell, thepositive strand is completed and transcribed. RNA transcripts arein turn reverse-transcribed into DNA by a viral enzyme in severalsteps, following closely the model of retroviruses, including ajump of the nascent positive strand from one direct repeat (DR)to another.

Eukaryotic organisms can have one or two copies of their chromosomes within the cell. When carrying two copies, the organism is said to be when carrying one copy, the organism is said to be When eukaryotic cells replicate their DNA prior to cell division it’s called

E. Poxviruses - The striking feature of poxvirus DNA isthat the two complementary strands are joined. The replicativeintermediates, present in the cytoplasm, are special concatemerscontaining pairs of genomes connected either head to head or tailto tail.

Class I (e.g. picornaviruses, flaviviruses.) The genome,having +ve polarity, itself act as the messenger, specifyinginformation for the synthesis of both structural andnonstructural proteins. The same RNA molecule also initiatereplication that requires the expression of proteins first. Thisformat allows little control over replication e.g. Poliovirus hasno independent mechanism of controlling the numbers of structuralproteins made.

Processes of DNA Replication and Protein Synthesis 2

Next, DNA replication and cell division happen again on these two haploid cells to give four final haploid cells. In complex eukaryotic organisms, these are the cells used for reproduction (egg and sperm), but in eukaryotic microorganisms these are the spores.

Class V (e.g. arenaviruses, phleboviruses.)Arenaviruses have an ambisense genome in that half the genome isof -ve polarity and is transcribed into a messenger by a viriontranscriptase, but the other half, which is of +ve polarity istranscribed twice: first a complete transcript of the genome ismade, then the mRNA is transcribed form this transcript. Thisstrategy is seen in the S (small) segment of the genome ofphleboviruses. Ambisense genomes are unusual for RNA viruses butnot for dsDNA viruses.
