The twisted ladder metaphorA DNA molecule is often likened to a spiral (or twisted) ladder. In this analogy, the rungs of the ladder are the base pairs (A-T and G-C). The sides of the ladder are the sugar-phosphate backbones of the two strands.This refers to B form DNA. molecule of DNA is double-stranded. The molecule has the shape of a double helix, typically right handed (B form DNA).
FRESH PORK: Safe Cooking Chart. Cook all raw pork steaks, chops, and roasts to a minimum internal temperature of 145 Â°F as measured with a food thermometer before removing meat from the heat source. For safety and quality, allow meat to rest for at least three minutes before carving or consuming.
For beef and pork, you will want to cook it to an internal temperature of 155 degrees Farenheit. Test the temp at the thickest part of the meat. Me personally, I would preheat the oven to 250 degrees and put it in 3 hours before you are ready to serve. Keep an eye on it though. They will cook the same if they are similar in size.....beef roast and pork roast cook in the same way generally.
