Question

What do viral genomes look like compared to those of living organisms? Why is their genome so small?

What do prokaryotic genomes look like compared to those of eukaryotes? (review the five points in the powerpoint discussion)

Why is there such a strong correlation between genome size and gene number among prokaryotes?

What is a plasmid and what role do they play in bacterial genome evolution? Horizontal Gene Transfer

What does gene order tell us about the frequency of genome rearrangement in prokaryotes?

Codon Usage Bias, GC Content Bias, Review the causation for both of these.

How can GC content bias help us to identify instances of HGT?

What do eukaryotic genomes look like compared to those of prokaryotes?

Transposable Elements, What is their role in the evolution of eukaryotic genomes: gene disruption, chromosome shuffling

Isochore, Introns, What is the adaptive advantage of having introns?

How common is recombination in eukaryotic genomes generally? Is this consistent across the genome?

What is different about the telomeres and centromeres compared to other parts of chromosomes?

Explanation / Answer

Thanks for the question

A virus has either DNA or RNA and is called a DNA virus or RNA virus

The viral genome is always single or double stranded and is obviouslt smaller due to the morphological variance from living organisms

A majority of viruses have RNA genomes

Although their genome is small, it doesnt mean they are weak. They have the capability to destroy the homeostasis and functioning of a living organisms million times bigger than their size. Therefore underestimating the power of virus by its size would erronously fatal.

An apple base culture can trigger an introduction and exponential growth of the virus enough to destroy any living organism. Many laboratories and research facilities have had to shut down their entire operations just by one such error. Labs which were publishing journals after journals, were suddenly not able to even write a single page of sense. The light had been shut off and taken away from the labs. If a single culture medium with virus can bring so much destruction, then we can imagine their catostrophei. Why such a disastrous criminal waste of resources and massive educational advancemental efforts are prematurely killed is a symbol of the strenghth of the virus. Some even equate it it bio terrorism of the fight for control and dominance, universally. An example is the viral small pox which although eliminated, if re released can wipe out entire human race!!

Many lives and everything they bring along have brutally ended with viruses. It is no laughing matter. Nobody can play with or withstand natures fury. Size does not matter here. It s the power of destruction they bring along that s the issue. It can change personalities, nature, traits, types, cause reversal of matter, can turn health into sickness, introduce suffering, break bones, cause rapid aging, bring end of life, cause mental illness, suicidal ideation and basically doom. thats the power of a virus with a wrong culture medium.

Thanks
