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.

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.
Preheat oven to 210Â°C. Place pork on a rack over a roasting dish and put in oven. Roast for 15 minutes. Reduce temperature to 150Â°C and continue cooking for 45 minutes per 500g. To check pork is cooked, pierce the thickest part with a knife: if the juices run clear, the pork is cooked.
