Classification of viruses is based on all of the following excepta type of nucleic acid.

. D host infectede strandedness of nucleic. NF-κB nuclear factor κB. All these pathogens with the exception of retroviruses encode a specialized enzyme called RNA-dependent RNA polymerase RdRP which catalyze phosphodiester-bond formation between ribonucleotides NTPs in an RNA template-dependent manner.

RNA viruses replicate their genomes using virally encoded RNA-dependent RNA polymerase RdRp. Explain the viral reproductive cycle. First week only 499.

Up to 24 cash back 14. Unlike most organisms some viruses store their genetic information as RNA rather than DNA. RNA viruses encode a unique class of RNA-dependent RNA polymerases RdRPs to carry out their fully RNA-based genome replication and transcription.

Most RNA viruses carry which of the following enzymes. Biology questions and answers. As of May 2020 all known RNA viruses encoding an RNA-directed RNA polymerase are believed to form a monophyletic group known as the realm Riboviria.

This is a confusing way of saying that the enzyme reads RNA to produce RNA. Most RNA viruses carry which of the following enzymes. Pba Question 1 4 out of 4 points Most RNA viruses carry which of the following enzymes.

Like living organisms viruses have a need to express their DNA. A retrovirus is a virus whose genes are encoded in RNA and using an enzyme called reverse transcriptase replicates itself by first reverse-coding its genes into the DNA of the cells it infects. The majority of such RNA viruses fall into the kingdom Orthornavirae and the rest have a positioning not yet defined.

Double-stranded RNA viruses carry their own RNA synthesizing enzymes within their virions. O Lysozyme O RNA dependent RNA polymerase O DNA-dependent DNA polymerase O Reverse transcriptase ATP synthase Question 14 3 pts The definition of lysogeny is olysis of the host cell due to a phage. First a virus enters the cell and is uncoated releasing viral DNA and capsid proteins.

A researcher proposing to categorize viruses in the tree of life would need to. The genome a copy of the genome copy genome and mRNAs. 21 Most RNA viruses carry which of the following enzymes.

Retrovirus is the single-stranded RNA viruses which replicate through a DNA intermediate and therefore requires the RNA-dependent DNA polymerase or reverse transcriptase. To replicate their genomes RNA viruses use virally encoded RNA polymerases that can use RNA as a template. Viruses are not yet considered an organism because they dont have cell membranes organelles and do not carry out vital life functions although they do have a form of DNA or similar RNA.

The viral genome genetic material has the instructions aka genes to take over the host cell and to build new copies of itself. Most emerging and re-emerging human and animal viral diseases are associated with RNA viruses. The viral RNA-dependent RNA polymerase acts as both a transcriptase to transcribe mRNA as well as a replicase to replicate the RNA genome.

1 Which virus type does not need any of its own enzymesa double stranded DNA viruses b negative stranded RNA viruses c positive stranded RNA viruses d retroviruses 2 The protein coat that protects the viral nucleic acid is called _____a an envelope b a membrane c a capsule d a capsid 3 Plus strand RNA _____a can integrate into the hosts chromosome. C RNA dependent RNA polymerase. A DNA-dependent DNA polymerase B RNA-dependent RNA polymerase C reverse transcriptase D ATP synthase E lysozyme Answer.

During replication of the viral genome RdRp. Solution for why do negative -strand RNA viruses carry an active RdRp enzyme within the virus particle. Next host enzymes replicate the viral genome.

How do most RNA viruses replicate their genome. They have genomes that act as complementary strands from which messenger RNA mRNA is synthesized by the viral enzyme RNA-dependent RNA polymerase RdRp. Viral polymerases are the enzymes which play an important role in the viral genome transcription and replication.

Classification of viruses is based on all of the following excepta type of nucleic acid. Question 2 4 out of 4 points Host specificity of a virus is due to interactions between viral and cellular surface molecules. Once inside a cell the enzymes transcribe one of the RNA strands of the dsRNA genome to ssRNA within the virion which upon release into the cytoplasm through channels in the virion is translated by the host cell machinery.

Most RNA viruses carry which of the following enzymes. Start your trial now. A DNA-dependent DNA polymerase.

Pararetroviruse Class VII is DNA viruses which carry out reverse transcription. Most RNA viruses carry which of the following enzymes. Which of the following is the transcription factors are involved in HIV-1 transcription.

For the rotavirus the viral nucleocapsid remains intact in the cytoplasm with replication events occurring inside allowing the dsRNA to remain protected. Ophage DNA Is Incorporated into host cell DNA o attachment of a phage to a cell the period. Some viruses even have an RNA-dependent RNA polymerase.

Reverse transcriptase encodes DNA from the strand of RNA which. Most viruses carry very little within their capsid and envelope if they have one and the majority of their insides is genetic material made of either strands of deoxyribonucleic acid DNA or ribonucleic acid RNA. The RNA genome is the template for synthesis of additional RNA strands.

RNA dependent RNA polymerase. A Lysozyme BATP synthase C Reverse transcriptase D DNA-dependent DNA polymerase E RNA-dependent RNA polymerase. Question 13 3 pts Most RNA viruses carry which of the following enzymes.

DNA-dependent DNA polymerase RNA-dependent. Although the chemical nature of nucleotide addition is essentially shared by all nucleic acid polymerases the structural and mechanistic details taken by each polymerase class differ to various extents. Like other viruses retroviruses need to use the cellular machinery of the organisms they infect to make copies of themselves.

When classes IV and VI viruses infect cells only the Class IV genomes can function as mRNA. Negative-strand RNA viruses ssRNA viruses are a group of related viruses that have negative-sense single-stranded genomes made of ribonucleic acid. For the rotavirus the viral nucleocapsid remains intact in the cytoplasm with replication events occurring inside allowing the dsRNA to remain protected.

RNA dependent RNA polymerase.
