I would like to ask a question about PNA and Morpholino... I am sorry, I look at their structure images but I still couldn't see anything that can be called similarities. The Morpholino has ring structure which is the same as DNA but PNA has no rings at all... Would you please explain a...

a new study at McMasters University in Toronto has discovered that polution can alter your DNA, the research were done on mice, three categories, the first category lived in the middle of an industrial zone brething in heavily poluted air, the second lived on a farm with clean air, and the third...

Why is the DNA in eukaryotes an open ended string rather than a closed loop?

Mouse "born" without male's DNA! Just kidding :)

Do twins, that split from the same egg (is this maternal?) have the exact same DNA?

Ok, so how does DNA build things? Say, even something as simple as a virus. The virus inserts its DNA or RNA or whatever, and it's coded into proteins. So how does the protein make a shape? Like in that T4 virus that looks like the lunar lander thing, how do the proteins assemble into the...

http://www.Givnology.com/wholy.htm Sure, that's simple. Focus on bringing in lunar nose, then solar nose, and be the DNA microcosm of the universe, surrounded by spiraling energy bands (not snakes!), and finally consumated in the crown where they're "making out." Well at least there is a...

In my less than deep undestanding of the biological sciences I understand there is an Axiom that say that the mechainsim of DNA goes in one direction. The DNA will evolve and change and impose itself on the organism, but the process does not work in reverse. Of course thee was the retrovirus...

How does the sequence of nucleotides in DNA relate to the chemical nature of genes, mutations, and the way genes are inherited?

I would like to know what DNA really is. How is it formed or at what stage in cellular development does it come about. Is it contained within a Gene or is it separate? Is it the determini9ng factor as to a Humans' physical and mental traits? Thanks for helping if possible.

DNA nano-technology is rapidly coming to a point in which applications for mankind will have enormous implications. It now becomes evident that mankind can manipulate DNA that will eventually change the way we live, our health and the world around us...

So,... this strands of DNA is what makes everyone of us unique and they're in every organs, tissues, blood...etc right? When there is an organ transplant, the part(or organ) that you're accepting has its own genetic stature so doesn't the body reject the new part? Once you acquired a new...

What is the World Coming To?

I ran a PCR last week but did not get around to running the AGE until this week, so the PCR product sat for a roughly a week at -4*C. What are the odds that all my DNA is at the bottom or stuck to the sides? A friend of mine just suggested this to me, or I would have vortexed it before running...

I’m interested in current state and progress_point of research in field of using DNA and other Bio materials in developing informational systems (or applying it in some areas/ researches of IT). There’s lot’s of talking going on involving this subject, but no real information. Using google to...

Greetings. I just have a small question about DNA replication correction. My textbook states (might contain errors of translation): Now my question is about locating the place of the DNA error. Locating the place of a wrong nucleotide might seem logical, but how can the enzyme locate the...

Metrics, Dimensions, DNA In order to understand the images processed and viewed in remote sensing it is important to understand where these images are located, as products, and what the scaling for these domains actually constitutes in the multidimensional time-series. Non-locality theory...

What is considered the native form of DNA?

I'm trying to prove that my daughter is my daughter. We just did DNA testing, but either me or my daughter has a mutation in our DNA and the lab is having a hard time coming up with an answer. They said that they are 98.75% sure that I'mno the father, but they won't say I'm the father unless...

Is this possible? If so, must the person being tested have a significant percentage to be identified? I am unsure about one of my great-great grandparents lineage, and would like to know, since census records cannot be found. I have heard about something like this, I believe, something to do...

Can DNA be supercoiled while it is wrapped around Histones? We are often shown in Biology classes electron Photographs of Supercoiled DNA. Would this DNA in the picture be completely free of Histones? Or could the DNA visualised in the picture be supercoiled DNA already in its condensed...

I heard that a methylated cytosine converts into a thymine by the following mechanism: The metC during the replication of DNA is place w/ an A opposite, and after the second replication you get what looks like a C to T transition. But isn't the metC to T transition caused by the...
