In addition, polyploidy occurs in some tissues of animals that are otherwise diploid, such as human muscle tissues.[1] This is known as endopolyploidy. Species whose cells do not have nuclei, that is, Prokaryotes, may be polyploid organisms, as seen in the large bacterium Epulopiscium fishelsoni [1].
In other words, with whole cuts of meat it is the external temp, not the internal temp, that must exceed 160 degrees Fahrenheit. Normal cooking methods â sauteing, grilling, roasting, braising, etc. â raise surface temperatures far above 160 degrees Fahrenheit.
The meat is tender, juicy, and flavorful. Because of the increased concern with harmful bacteria that may be present in beef, medium-rare (145ÂºF on a meat thermometer, using updated guidelines) is the minimum degree of doneness that is recommended. Internal Temperature. of Beef Cooked Medium-Rare.
