HIV does not use transcriptase to make double-stranded RNA; rather, it uses reverse transcriptase to convert its single-stranded RNA genome into double-stranded DNA. This DNA is then integrated into the host cell's genome. The host's cellular machinery subsequently transcribes this DNA back into RNA, which can be translated into viral proteins or packaged into new virions. Thus, HIV primarily involves DNA synthesis rather than direct double-stranded RNA formation.
What else can I help you with?
Is it true or false that hiv uses reverse transcriptase to make ds RNA copies of its DNA genome?
False. HIV uses reverse transcriptase to make single-stranded RNA copies of its RNA genome.
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.
Which polynucleotide is single stranded?
Ribonucleic acid (RNA) is the polynucleotide that is typically single-stranded. Unlike DNA, which is double-stranded and forms a double helix, RNA can exist in various forms, including messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA), all of which are single-stranded. This single-stranded structure allows RNA to perform diverse functions in cellular processes, including protein synthesis and regulation.
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,
Is it true or false that hiv uses reverse transcriptase to make ds RNA copies of its DNA genome?
False. HIV uses reverse transcriptase to make single-stranded RNA copies of its RNA genome.
What does reverse transcriptase use from DNA?
Reverse transcriptase use mRNA to form DNA. mRNA
Retroviruses such as HIV contains what enzyme that enables DNA to be synthesized from rna?
Retroviruses such as HIV contain the enzyme called reverse transcriptase, which enables the synthesis of DNA from RNA. This DNA integrates into the host cell genome, allowing the virus to replicate and persist in the host.
Is RNA double stranded or single stranded?
RNA is typically single-stranded, unlike DNA which is double-stranded.
Is DNA or RNA double stranded?
DNA is double stranded, while RNA is typically single stranded.
Is RNA double or single stranded?
RNA is typically single-stranded, unlike DNA which is double-stranded.
Is RNA a double-stranded molecule?
No, RNA is a single-stranded molecule.
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.
Is DNA or RNA single-stranded?
RNA is typically single-stranded, while DNA is double-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 it true that both DNA and RNA are double-stranded molecules?
No, DNA is typically double-stranded, while RNA is usually single-stranded.
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.
