2011年5月27日 · To my mind DNA is information in the same way that any constituent molecule of a chemical reaction is information. DNA is a molecule that facilitates specific chemical reactions that result in the working of a biological system. To bring in notions of code/information/language is only useful for analogy.

2015年2月26日 · Dna Information In summary, the conversation revolves around a creationist claiming that no DNA can be added to a genome and asking for help in finding experiments or sources that prove this. However, it is not true as genetic engineering is based on the addition of DNA to a genome, such as through the use of Green Fluorescent Protein.

2015年6月19日 · A gene is a set of bases in one strand of the DNA which encodes the information necessary to construct a useful protein. The opposite DNA strand is it's exact complement in terms of encoding but does not construct anything useful It serves the purpose only of replicating it's complimentary and active gene, ( which is necessary for replication).

2008年12月18日 · The DNA encodes the information needed to create a brain. It is the brain (neuron structure) which is responsible for causing certain types of behavior. DNA is considered the 'code' responsible for creating the 'hardware' of the brain, and that code has in it, the information needed to create the proper neuron structure.

2013年11月9日 · In summary, DNA profiling is a process of analyzing genetic material to identify a person. It is used to convict criminals, to determine the identity of a deceased person, and to identify a person who has been kidnapped. However, DNA profiling is not always reliable, and it is possible for two people to have the same DNA even if they are unrelated.

2023年1月10日 · For DNA sequences, it quantifies the variability in the sequence composition, providing insights into the complexity and information content of the genetic material. High entropy indicates a more diverse sequence, while low entropy …

2015年10月6日 · Genetic structure means something specific, I'm not sure what you mean by it here. If you're asking if DNA is the only way to encode genes the answer is no, there are other molecules that can do the job, RNA viruses don't use DNA for example, but in nature DNA is vastly more ubiquitous because it has favourable chemical properties like being stable over much longer time scales.

2012年3月21日 · Homework Statement The length of DNA helix occupied by one nucleotide pair is 3.4 A (angstrom). A human has 10^14 cells and each human cell has about 6.4 x 10^9 nucleotide pairs of DNA. What is the length of double helix that could be formed from this amount of DNA in a human individual...

2016年7月18日 · What kind of information can you get from looking at a stretched-out molecule? You certainly cannot get sequence information, because the resolution is not nearly good enough. You can, however, look at the large-scale structures, which current sequencing techniques cannot access because they have to stitch together tiny strands of DNA.

2004年5月29日 · To begin, we can use the given information to calculate the change in length of the DNA molecule when it becomes charged. We know that the original length of the molecule is 2.17μm and it compresses 1.00% when charged, so the change in …
