If RNA is used as a genetic molecule, passing traits from parent to offspring, then it is subject to natural selection.

This only happens in a number of viruses and very few bacteria, though: most organisms use DNA as their genetic molecule.

How could RNA have become involved in the mechanism for protein translation?

natural selection favored RNA molecules that synthesized catalytic proteins


Explain how early RNA molecules might have been able to respond to natural selection?

Early RNA molecules may have varied in their ability to catalyze reactions or replicate themselves, leading to differences in survival and reproduction. Those RNA molecules with beneficial traits would have had a selective advantage, allowing them to increase in frequency within the population over time through natural selection.


What type of polmer is RNA?

RNA is natural polymer.


Why could RNA evolve before DNA?

I think It's because RNA is less complex than DNA.


In eukaryotes all of RNA are transcribed or produced in the?

In eukaryotes, all RNA molecules are transcribed in the nucleus. This includes messenger RNA (mRNA), ribosomal RNA (rRNA), and transfer RNA (tRNA). While some RNA molecules may undergo further processing and modification in the cytoplasm, their initial transcription occurs in the nucleus.


What is SC RNA?

RNA molecules found in the cytosol and rough endoplasmic reticulum associated with proteins that are involved in specific selection and transport of other proteins.


What are the 4 types of natural selection?

The four types of natural selection are stabilizing selection (where the average phenotype is favored), directional selection (where one extreme phenotype is favored), disruptive selection (where both extreme phenotypes are favored), and sexual selection (where traits that increase mating success are favored).


Why don't RNA viruses undergo provirus formation?

RNA viruses typically do not undergo provirus formation because they replicate their RNA genomes directly within the host cell's cytoplasm, rather than integrating into the host's DNA. While some RNA viruses, like retroviruses, can convert their RNA into DNA and integrate into the host genome, most RNA viruses do not possess the necessary reverse transcriptase enzyme and integration machinery. Consequently, they replicate and produce new viral particles without the stable, long-term presence in the host's genetic material that characterizes provirus formation.


Why does influenza have RNA?

Influenza is an RNA virus because its genetic material is made up of RNA. RNA viruses like influenza are able to mutate more rapidly than DNA viruses, which contributes to the virus's ability to evolve quickly and evade host immunity.


Where does the transcription of ribonucleic acid RNA take place in a cell?

Transcription of RNA takes place in the nucleus of a cell. The DNA containing the genetic information is transcribed into RNA by an enzyme called RNA polymerase. Once transcribed, the RNA molecule may undergo further processing before being transported to the cytoplasm for translation.


RNA?

Ribonucleic acid or RNA for short is a DNA in microorganisms that can be accessed by the microorganism once in a while and mutate or evolve whenever the viral agent consumes genes and proves that the virus is a consumer but it is not 100% true that it is alive itself
