There is a somewhat common belief that playing a tone at 528Hz can help to facilitate DNA repair. Examples: The frequency of 528 Hz supposedly has healing effects on DNA. The frequency seems to influence the water molecules that surround the DNA helix. - Souls of Distortion Awakening. These six frequencies, and their related effects, are as ...
Normal viruses infect cells in order to take advantage of cellular mechanisms to reproduce themselves. A class of viruses known as "retroviruses" have a slightly peculiar mechanism to achieve this - they synthesise a special enzyme called "reverse transcriptase", which translates their own RNA into DNA which is incorporated into the host cell's genome.
Sharing 99% of genes is not the same as sharing 99% of DNA. While we may have nearly the same number and type of genes (i.e. rat genes have counterparts in the human genome) it does not mean that these genes are completely identical. They are comparing the number and function of the genes only.They are NOT comparing the actual DNA sequences.
Molecular phylogenetics (i.e. inferring relatedness from DNA sequences) produces results that are consistent with other methods of inferring relatedness among species: morphology, geography, and the fossil record. Therefore, it adds credibility to the only theory that predicts these patterns, evolution from a common ancestor.
Since the advent of cheap DNA tests, several companies have sprung up which will tell you ancestral origins according to your DNA. 23andMe claims, Where in the world are you from? Find out where your DNA comes from around the world. Your DNA can tell you where your ancestors lived more than 500 years ago.
A friend of mine recently took a DNA ancestry test using one of these mail-order services. Sadly he did not provide the name of the company used. According to his results, he has partial Native American ancestry.
So the best estimate is 9.5 × 10 12 cells with chromosomal DNA. According to Lehninger Principles of Biochemistry the length of DNA in a diploid human cell is 2 meters. So the total length of cellular DNA in human is 1.9 × 10 13 meters. This is about 3 times the distance to Pluto, the distance to Pluto averaging 6.1 × 10 12 meters.
The amino-acids constitute the building blocks for many different chemicals made inside the body: in hormones, enzymes, DNA. encoding, RNA. encoding.... they play vital roles in the body's immune system, they constitute the neurotransmitters in the brain, the cortisol which is involved with stress response - in short we know a fair bit about ...
One paper merely notes that 1342 cm-1 and 1571 cm-1 are tell-tale of DNA or RNA. Another explains in somewhat more detail that 1343 cm-1 corresponds to "adenine residue", whereas 1573 cm-1 to "nearly equal contribution from A[denine] and G[uanine]".
Setting aside the issue of whether prions are considered "alive" (which is as much about English definitions as any facts), there is the question of whether they came from RNA/DNA. In ScienceDaily , they reported about a study that looked at the evolutionary origins.
