Is DNA and RNA double-standard?
No, DNA is usually double-stranded, consisting of two strands that are complementary to each other. RNA, on the other hand, is usually single-stranded. There are exceptions to this, such as certain viral RNA genomes that can be double-stranded.
Is influenza a viral infection?
No, influenza is a negatively stranded RNA virus belonging to the orthomxyoviridae family. Retroviruses are also RNA viruses but convert the RNA to DNA once inside the cell, with reverse transcriptase.
Is influenza single strand or double strand RNA?
It is single stranded RNA. Importantly, it is also a segmented genome that allows it to have large genetic diversity.
Is RNA found in a double stranded state in the cyoplasm?
It depends what you mean by double stranded. If you mean two separate RNA strands, perfectly complementary to one another and existing as a basepaired structure in the cytoplasm, then no. Double stranded RNA like that only occurs in some types of viruses (and cells infected by them... so I guess the cytoplasm of a cell infected by a double stranded virus might have a lot of this kind of double stranded RNA). However, if you mean double stranded in the sense of a single RNA molecule folding back on itself and basepairing with itself - forming stem loops and more complicated structures - that kind of RNA double-strandedness is extremely common. All tRNA's and rRNA's for example exhibit this kind of double-strandedness. Nucleic acids are unstable in single stranded states and will spontaneously fold back on themselves if there is no other strand to basepair with. Nucleic acids are inherently unstable in a single stranded state. Thus,
Does Virus contain both DNA and RNA?
Infuenza Virus Contain Both DNA and RNA. No other Virus show such characteristics.
Retroviruses such as HIV contains what enzyme that enables DNA to be synthesized from rna?
by using reverse transcriptase to help produce double stranded DNA from viral RNA
What is MMLV Reverse Transcriptase?
MMLV Reverse Transcriptase is a recombinant DNA polymerase which synthesizes a complementary DNA strand from single-stranded RNA, DNA, or an RNA.
Is trna double stranded or single stranded?
tRNA, or transfer RNA, is a single stranded molecule. The only double stranded RNA is dsRNA, or double stranded RNA. They are typically found in viruses.
How many strands is RNA made of?
in humans there is one strand of RNA, hence the name single-stranded RNA. However, in some viruses (such as HIV), there are double-stranded RNA made by the enzyme transcriptase.
Is DNA or RNA triple stranded?
DNA is generally double stranded and RNA is single stranded.
Hiv is a virus affecting RNA or DNA?
HIV affects the DNA of the host cell by incorporating the double stranded DNA synthesized from reverse transcriptase as a provirus into the cell's DNA. These proviral genes are then transcribed into RNA molecules.
Is DNA and RNA double-standard?
No, DNA is usually double-stranded, consisting of two strands that are complementary to each other. RNA, on the other hand, is usually single-stranded. There are exceptions to this, such as certain viral RNA genomes that can be double-stranded.
What is a description of the structure of DNA and RNA?
DNA is double stranded whereas RNA is single stranded . They are different in their functioning as well .
Is the RNA made up of double strand of nucleotides?
NO, RNA is almost always single stranded. The only exception is in certain viruses that contain double-stranded RNA.
RNA is single stranded?
mRNA, or messenger RNA is single stranded, and so are transfer RNA, snRNA, hnRNA, and ribosomal RNA. The exception are some viral RNA's, that can be double stranded. Remember that despite having Uracil instead of Thymine, RNA can base pair anyway, just like in the case of the beforementioned RNA-viruses.
What is ssRNA-RT viruses?
These are the retro single-stranded RNA. These viruses make DNA from RNA using an enzyme called reverse transcriptase. One of the most famous example of the ssRNA-RT virus is the HIV virus.
What is the major difference between normal DNA double helix and RNA double helix?
The term double helix refers to the structure formed by double-stranded molecules of nucleic acids. Only DNA forms a double helix because RNA is only single-stranded.
