The foundations of molecular genetics were laid in the pre-1956 era by the discovery of DNA, called nuclein, by Miescher in 1867; the demonstration that the pneumococcal transforming factor is DNA by Oswald Avery, Colin MacLeod, and Maclyn McCarty (1944); and the solution of the structure of...

Much of the skeletal structure is taken up by the huge skull, which supports the large ears, tusks, and trunk. The skull contains big cavities that reduce the weight without diminishing the strength. Apart from several other physical differences, Asian elephants differ from African elephants in ...
However, the EDA gene exhibits no specific expression in any tissue in the human GTEx dataset (Fig. S7). We further examined the graph structure of the TNFRSF19 where the significant NRS occurred. Our investigation revealed that this bubble occurred in the fourth intron of the TNFRSF19 gene...
This is the same substance found in nails, hair, claws, and hooves. However, as opposed to deer, which the antelope is often compared to, antelopes keep the same horns for their entire lives instead of shedding them every year. The structure and shape of antelope horns vary widely. Some ...
The wing structure itself does the destroying by tearing apart the bacteria. The wings have nanoscale-sized pillars that trap and slowly kill bacteria by pulling their cells apart. Researchers hope to mimic these on surfaces in public places. Advertisement - Continue Reading Below Atelopus//Getty ...
The slim physique (which provides balance), the specialized hoofs (which can grip irregular surfaces), and the muscular structure all seem to play a vital role in allowing the goat to ascend steep areas without falling. These animals also can leap some 5 feet into the air to reach otherwise...
The structure of their feet and legs means that they are also able to jump distances over 10 meters. Lionhearts weigh about 1,175 grams, which in relation to their body size is significantly smaller than many of the herbivores they hunt. Their heart and lung size mean lions can only ...
