Within a double-stranded DNA molecule, adenine forms hydrogen bonds with thymine, and cytosine forms hydrogen bonds with guanine This signifies <u>determining the type of protein produced</u>
DNA's unique structure enables the molecule to copy itself during cell division. The double-helix shape allows for DNA replication and protein synthesis to occur. Each of the two strands in double-stranded DNA acts as a template to produce two new strands.
Replication relies on complementary base pairing, that is the principle explained by Chargaff's rules: adenine (A) always bonds with thymine (T) and cytosine (C) always bonds with guanine (G).

The physiological process occurring in the muscle cells that account for the gradual onset of muscle fatigue is called anaerobic the body is breaking down oxygen after than it can get in.
Answer:
This means that the two separate rocks were once part of one piece of rock. These layers got separated most probably by continental drift as a result of tectonic plate movements. An example of such a fossil is the Mesosaurus, a freshwater crocodile-like reptile, that is found in Southern Africa and Eastern South America continents- that means they were once one land mass.
The environment in these two separate layers would most likely be different. As the layers drift apart from each other , they drift across latitudes that are determinants of climate in a region. Therefore, even the organisms in these two rock layers will evolve differently (even though they will share a common ancestor) in adaptation to respective environments – this is called allopatric speciation.
