Q:During viral R/DNA replication, do viruses take advantage of the cell's ordinary error checking mechanisms?

I think it depends on the virus. Many virus contain their own DNA / RNA polymerases that they use to replicate. Retroviruses for example have reverse transcriptase which synthesizes DNA from RNA, something that is not used by anything else. Not being proofread is what has allowed viruses to thrive, because it causes mutations that host organisms have to adapt to. Notice how there's a new flu shot every year? That's caused by antigenic drift.

Q:Please read this article and tell me

Well, it starts out lying about Lenski's long term E. coli evolution experiment. Being able to metabolize citrate is not a minor change. Being citrate negative is in the very definition of E. coli. The dishonest streak continues. They fully admit the group previously showed how it could have easily evolved from the proposed ancestral receptor. The reverse being unlikely doesn't affect a thing, since it didn't evolve in reverse. This is typical Evolution News and Views. They cannot directly challenge the overwhelming evidence supporting common descent, so they lie and distort data constantly. Edit: To be brief, for the receptor to evolve back to its ancestral state, first five separate mutations would have to happen. Each mutation kills the receptor, so genetic drift alone would be responsible. Once these five mutations are made, then the receptor could mutate to the functional ancestral form. This makes it very, very, very unlikely, but still technically possible. While interesting, this means little. The same group discovered only a few mutations are needed to switch from the ancestral to the modern form. Once there those five mutations each make its new function better, so there was a selective pressure for them, but they also locked away from the older state.

Q:List four fundamental differences between bacterial and eukaryotic transcription machinery.?

Bacterial - RNAp is only of 1 type and has 5 subunits. - Sigma factor does the promoter recognition. - alphaCTD is not involved in the RNAp control, but instead binds UP elements - Poly(A) tail is not added to the RNA produced. - No introns are present, hence no splicing machinery. - GTFs are absent. - The process is relatively simple. Eucaryotes - RNAp is of more than 4 types and has about 12 subunits. - TFIIB and many other factors do the promoter recognition. - CTD of RNAp plays important role in regulation and elongation and many other processes. - Poly(A) tail is added to the RNA produced. - Splicing machinery is present due to need for intron splicing - GTFs are present. - The process is relatively very complex.

Q:I'm looking for a small lathe to place in my barn.

With the way the economy is today and with manufacturing companies going under you might be able to find a cheap machine at a local auction in your city. The market is flooded with a bunch of cheap machines that you can probably pick up at a cheap price. If you cant find a machine at an auction search the internet for a used machinery dealer. I’ve used JS Peters Machinery Sales in the past and they have done a decent job.

Q:I wanna go into the woodwool or wood shredder manufacturing...plz tell where the machinery can b bought from? second hand m/c will also work........thnx a tonnn

No body knows. Try google or craigslist or OKorder.

Q:title says it alllWill it ever be possible for scientists to physically stop a earthquake with any machinery or something like that

An earthquake is the moving of the tectonic plates. So you'd need some huge machinery to stop it.

Q:I want to sign up for a construction machinery rental company! What should I do? Steps? How much do you charge for a year?

Registered company general search process: (the administrative department for Industry and Commerce), bank (bank), capital verification (accounting firm) to apply for a business license (the administrative department for Industry and Commerce) to apply for organization code certificate (Department of quality and technical supervision) to apply for tax registration certificate (tax authorities)

Q:How do the proteins of the transcription machinery access DNA that is tightly associated in chromatin?

Chromatin is tightly condensed to chromosomes only during mitotic/meiotic phases and not all the time. In your body, right now there are several cells which are not dividing and hence the DNA is freely available coiled around histone proteins. Transcription machinery access DNA by unwinding DNA from histones (histone deacetylases) initially. Later DNA gyrase unwinds the coiled DNA (like zip open) where the transcription machinery acts.

Q:what are the methods to depreciate machineries ?

In addition to the above you can depreciate based on usage, either in hours or another appropriate form of measurement such as widgets processed. Cars can be depreciated based on miles driven.
