Efforts to understand how proteins are encoded began after DNA's structure was discovered in 1953. The key discoverers, English biophysicist Francis Crick and American biologist James Watson, working together at the Cavendish Laboratory of the University of Cambridge, hypothesied that information flows from DNA and that there is a link between DNA and proteins.

The resulting viral DNA is then imported into the cell nucleus and integrated into the cellular DNA by a virally encoded enzyme, integrase, and host co-factors. [18] Once integrated, the virus may become latent , allowing the virus and its host cell to avoid detection by the immune system, for an indeterminate amount of time. [ 19 ]
Mutations are not entirely random, nor do they occur at the same frequency everywhere in the genome. Certain regions of an organism's genome will be more or less likely to undergo mutation depending on the presence of DNA repair mechanisms and other mutation biases.
Lamarck argued, as part of his theory of heredity, that a blacksmith's sons inherit the strong muscles he acquires from his work. [1]Lamarckism, also known as Lamarckian inheritance or neo-Lamarckism, [2] is the notion that an organism can pass on to its offspring physical characteristics that the parent organism acquired through use or disuse during its lifetime.
Cardiovascular disease (CVD) is any disease involving the heart or blood vessels. [3] CVDs constitute a class of diseases that includes: coronary artery diseases (e.g. angina, heart attack), heart failure, hypertensive heart disease, rheumatic heart disease, cardiomyopathy, arrhythmia, congenital heart disease, valvular heart disease, carditis, aortic aneurysms, peripheral artery disease ...
