This question is both easy and hard to answer: DNA and its (known) functions have been described in scientific literature, textbooks and databases for the last few decades, but because this is a enormous amount of data there is no single source or collection that could comprehensively catalog all this information. Information on genomes and genes has been ...

The answer is complicated. In the early days of molecular phylogenetics, it was extremely difficult to demonstrate whether chimps or gorillas are our closest relatives. This is because the common ancestor of chimps and humans lived between 5 and 8 million years ago, and the common ancestor of gorillas and humans (and chimps) lived around the same time, just ...

Mutation in DNA can be beneficial, harmful, or may have no effect. This is dependent on the gene location where this mutation has occurred. Various genes linked to cancer are: Tumor suppressor genes: These genes regulate cell growth by keeping check on cell division, repairing mismatched DNA and regulating cell death. Mutation in this type of gene leads ...

When you look in the mirror, you see yourself. That puts you in the company of animals like dolphins, elephants, chimpanzees, and magpies, all of whom have shown the ability to recognize their own reflections. The mirror test is often used as a way of measuring whether animals possess self-awareness. Some fish have recently passed the test, which has left ...

Are there specific genes for self-consciousness that makes a particular animal conscious ? The mechanism of self-consciousness in the brain (in the cortex) is separate from the formation of the brain which is separate from the genetic control of the brain development. You want an answer for the genetic control of the brain development (cell differentiation, ...

DNA is considered to be the blueprint from which any organism can be created It's the main blueprint, true, but in order for DNA to be functional it needs a complex composition of proteins, ions, membranes, sugars etc.. You know, all your cells have the same DNA, yet they all are different! A friend of mine, a leading expert in stem cell manipulation, is ...

Nothing! If DNA is one way of doing life–which is not well defined–it has shown that in all its forms it has been creating organisms with some form of intelligence. If you can accept that there can be different levels of consciousness and intelligence, then it may almost be easier to ask which organisms have zero consciousness? Here's a video showing that ...

While we likely do not know exactly what constitutes consciousness, we can likely surmise that other organisms are conscious (or at least show what we might call self-awareness), and we can probably agree that the brain (or at least a nervous system) is an organ critical to developing and maintaining consciousness in an organism. The Hox family of genes (and ...

I interpret your question to ask this: Can DNA origami be used as scaffolds for the guided assembly of other non-DNA structures? Yes. From what I've read, two- and three-dimensional DNA structures can be used for nanoparticle assembly and as a nucleation factor in the crystallization of proteins and minerals. You can find these examples and more in a ...

Well, the evolutionary reason is the one you mentioned: the thermostability of Taq allowed its bacterium to colonize high-temperature environments. That, however, does not say anything about the molecular reasons for this difference. I found this very good answer on Quora. The end of the post has several references for its claims. Long story short, the ...
