There is no difference in base pairing between different kinds of organisms. Humans, animals and bacteria all share the same fundamental mechanisms as they all use DNA. Which bases can pair is determined by the chemistry of the individual bases. The bases in DNA form the following hydrogen bonds when they are paired: If you would try to combine other ...

No — typical DNA extraction will not preserve information about the biochemical state of the cell. During the process of DNA extraction, proteins are removed and DNA from a population of cells gets precipitated. Then you dissolve the DNA. In this process native conformational state cannot be preserved. However there are techniques (see this post) that ...

I have read that cohesin is one of such enzymes, but works as a transcription factor by binding specific DNA motifs. Cohesin binding is not motif dependent (like transcription factors) and is also dynamic. Though sequence may have a role it is, just as in the case of nucleosomes, mostly the overall composition rather than a sequence based motif: ...

The structure allows for the DNA to be tightly packed into chromosomes. It also provides an extremely stable backbone with the negatively charged phosphates pointing to the outside of the molecule. This charge aids in the attachment of other molecules to the strand of DNA. DNA double helix allows it to be stable and it won't easily destroyed.

Wobble pairing is just a phenomenon and not a hard and fast rule. There are some justifications for why it should exist and that is why it is still called a hypothesis. And this statement is not true:"the base on the third position of the codon and that on the anticodon need not be complementary". The anticodon residue corresponding to the third residue of ...

The most important role of this peculiar double helix structure of DNA is to facilitate replication....in preparation of cell division each of the 2 strands acts as a template thus facilitating precise copying of genes....in the Nature(1953), Watson & Crick also suggested that " It has not escaped our notice that the specific pairing we have postulated ...

An embryo is called a fetus at a more advanced stage of development and up until birth or hatching. In humans, this is from the eighth week of gestation. However, animals which develop in eggs outside the mother's body are usually referred to as embryos throughout development; e.g. one would refer to a chick embryo, not a "chick fetus" even at ...

I hope you might edit your question to give examples of such comparative injuries. I'm trying hard to imagine an example of this phenomenon, but I can't. The human body doesn't have a tripwire, or a lower limit of injury under which it will not respond. Normally the body mounts appropriate defenses against all injuries from the very minor, like a paper cut, ...

As far as I know there are ongoing efforts to find genes that affect forensically relevant traits e.g. facial characteristics and fingerprint pattern type/ridge count, and it's definitely a topic of interest to some law enforcement agencies. However as previously mentioned, there are many factors that could influence complex traits, including in utero ...
