Question 2 4 out of 4 points Host specificity of a virus is due to interactions between viral and cellular surface molecules.

. The best characterized conventional RNA-capping system is that exemplified by the dsDNA virus vaccinia virus which expresses a multifunctional mRNA cap-synthesizing enzyme D1 containing RTPase. 6 What is the correct sequence of the steps in the virus reproduction process. 2 What is the correct order for the stages of a lytic replication cycle.

4 Which of these enzymes is necessary for the replication of a strand RNA virus. First week only 499. Because their host cells have dsDNA genomes viruses with RNA genomes cannot rely on host cell enzymes for genome replication or mRNA synthesis.

To carry oxygen round. RNA is found in every cell in the body and plays an important role in the flow of genetic information. This viral DNA then migrates to.

Most RNA viruses carry which of the following enzymes. The cell uses RNA for a number of different tasks one of which is called messenger RNA or mRNA. Mechanisms of Genome Transcription and Replication.

Question 13 3 pts Most RNA viruses carry which of the following enzymes. Classification of viruses is based on all of the following excepta type of nucleic acid. For the rotavirus the viral nucleocapsid remains intact in the cytoplasm with replication events occurring inside allowing the dsRNA to remain protected.

Asked Mar 24 2017 in Biology Microbiology by FindaCure. Next to the common cold influenza or the flu is perhaps the most familiar respiratory infection in the world. They have genomes that act as complementary strands from which messenger RNA mRNA is synthesized by the viral enzyme RNA-dependent RNA polymerase RdRp.

During replication of RNA viruses there are at least three types of RNA that must be synthesized. A DNA-dependent DNA polymerase B RNA-dependent RNA polymerase C reverse transcriptase D ATP synthase E lysozyme Answer. Negative-strand RNA viruses ssRNA viruses are a group of related viruses that have negative-sense single-stranded genomes made of ribonucleic acid.

B shape of virusc size of virus. 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. RNA or ribonucleic acid is a nucleic acid that is similar in structure to DNA but different in subtle ways.

RNA viruses replicate their genomes using virally encoded RNA-dependent RNA polymerase RdRp. RNase P a ribonuclease that generates tRNA molecules from larger precursor RNAs was one of the first ribozymes to be discovered. The RNA genome is the template for synthesis of additional RNA strands.

Asked Aug 9 2019 in Biology Microbiology by AlienX. 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. When the virus enters a host cell a viral enzyme reverse transcriptase converts that single-stranded RNA into double-stranded DNA.

The genome a copy of the genome copy genome and mRNAs. Latesha Elopre MD MSPH 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. Ophage DNA Is Incorporated into host cell DNA o attachment of a.

3 What enzyme do most RNA viruses carry. In the United States alone approximately 25 to 50 million people contract influenza each year. The symptoms of the flu are similar to those of the common cold but tend to be more severe.

RNA dependent RNA polymerase. RNA viruses require their own supply of certain enzymes becauseA host cells rapidly destroy the virusesB host cells lack enzymes that can replicate the viral genomeC these enzymes translate viral mRNA into proteinsD these enzymes penetrate host cell membranes. A Lysozyme BATP synthase C Reverse transcriptase D DNA-dependent DNA polymerase E RNA-dependent RNA polymerase.

D host infectede strandedness of nucleic. Solution for why do negative -strand RNA viruses carry an active RdRp enzyme within the virus particle. Like other viruses retroviruses need to use the cellular machinery of the organisms they infect to make copies of themselves.

MRNA rRNA and tRNA. Many factors contribute to the high mutation rates in RNA viruses including the instability of RNA and the poor proof reading activity in the enzymes that replicate RNA. Start your trial now.

And that is the nucleic acid information molecule that transfers information from the genome into proteins by translation. R olling c ircle r eplication RCR is important to circular ssDNA genome replication eg ΦX174 phage and. RNA dependent RNA polymerase.

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. Pba Question 1 4 out of 4 points Most RNA viruses carry which of the following enzymes. The viral RNA-dependent RNA polymerase acts as both a transcriptase to transcribe mRNA as well as a replicase to replicate the RNA genome.
