Nucleoside analogs interfere with viral replication by being incorporated into viral DNA or RNA during replication, which disrupts the normal functioning of the virus. This disruption prevents the virus from replicating efficiently and ultimately leads to its inhibition.

What is the mode of action of nucleoside and nucleotide analogs?

Nucleoside and nucleotide analogs inhibit viral replication by incorporating into the viral genome during replication. These analogs lack the necessary functional groups for further elongation of the viral genome, leading to termination of viral replication and inhibition of viral protein synthesis. This disruption ultimately stops the virus from spreading and replicating.


Are nucleoside analogs that inhibit DNA synthesis effective against viral diseases?

Yes, nucleoside analogs that inhibit DNA synthesis are effective against viral diseases because they can interfere with viral replication by disrupting the synthesis of viral DNA. These analogs can be incorporated into viral DNA, causing errors in replication and ultimately inhibiting viral replication and spread within the body.


Difference between nucleoside reverse trancriptase inhibitor and non nucleoside reverse transcriptase inhibitor?

They have a different mode of action in inhibiting the transcription of the viral DNA. The NRTI is actually a nucleoside that incorporates into the viral DNA but it does not have a 3-hydroxyl group so it inhibits and halts the continued growth of the viral DNA chain. The NNRTI's bind to the reverse transcriptase and inhibit its movement.

What are the differences between nucleoside triphosphate and nucleotide triphosphate, and how do these molecules function in cellular processes?

Nucleoside triphosphate is a molecule consisting of a nucleoside (sugar and nitrogenous base) and three phosphate groups, while nucleotide triphosphate includes a nucleoside, phosphate groups, and additional functional groups. Both molecules serve as energy carriers in cellular processes, providing the energy needed for various biochemical reactions. Nucleoside triphosphates are involved in DNA and RNA synthesis, while nucleotide triphosphates are essential for protein synthesis and cell signaling.


What is included in corticosteroids?

These analogs include glucocorticoids, which are anti-inflammatory agents with a large number of other functions; mineralocorticoids, which control salt and water balance primarily through action on the kidneys; and corticotropins.


What is the difference between nucleoside triphosphate and nucleotide, and how do they function in cellular processes?

Nucleoside triphosphate is a molecule made up of a nucleoside (sugar and base) and three phosphate groups, while a nucleotide is a molecule made up of a nucleoside and one or more phosphate groups. Nucleoside triphosphates serve as energy carriers in cellular processes, providing the energy needed for reactions like DNA replication and protein synthesis. Nucleotides are the building blocks of nucleic acids like DNA and RNA, playing a crucial role in genetic information storage and transfer within cells.


Why can't the human immune system eliminate herpes viruses from neurons?

Current first line treatments for HSV-1 (Herpes Simplex Virus type I, usually in the mouth region) and HSV-2 (Herpes Simplex Virus type II, usually in the genital region) are Acyclovir, Valacyclovir and Famcicolovir. These drugs are nucleoside analogs. Their method of action is to prevent the production or new viral genetic material by inserting themselves into the viral DNA and terminating synthesis. Therefore, they are only functional against stopping the production of new viruses. These drugs cannot kill existing viruses lying dormant in the neuron. Currently no drug exists to kill dormant (non-replicating) HSV-1 or HSV-2 in the body.


What is the difference between a nucleotide and a nucleoside in terms of their structure and function?

A nucleotide consists of a nucleoside (sugar and base) with a phosphate group attached, while a nucleoside is just the sugar and base. Nucleotides are the building blocks of DNA and RNA, carrying genetic information, while nucleosides are involved in energy transfer and cell signaling.

The components of a nucleoside are?

The components of a nucleoside are: A pentose sugar(generally ribose or deoxyribose), and a nitrogenous base which may be Adenine/Guanine/Thymine/Cytosine/Uracil. It becomes a nucleotide on addition of a phosphate group.


Founder of the method of physical action is?

The founder of the Method of Physical Action is Konstantin Stanislavski, a Russian theatre practitioner. This method was part of the later development of his acting system, where he emphasized that purposeful physical actions can naturally lead to genuine emotions, rather than starting with emotional recall. It marked a shift from internal to external techniques, helping actors achieve believable performances through physical behavior. nsda.portal.gov.bd/
