DNA. DNA (or deoxyribonucleic acid) is the molecule that carries the genetic information in all cellular forms of life and some viruses. It belongs to a class of molecules called the nucleic acids, which are polynucleotides-that is, long chains of nucleotides.Each nucleotide consists of three components:NA (or deoxyribonucleic acid) is the molecule that carries the genetic information in all cellular forms of life and some viruses.

1 Approximate cooking times and required temperature based on a 4 to 6 pound rib eye roast in a 350 degrees F oven: 2  RARE (140 degrees F): 18 to 20 minutes per pound.3  MEDIUM RARE (145 degrees F): 20 to 22 minutes per pound. 4  MEDIUM (160 degrees F): 20 to 24 minutes per pound.

3 Preheat your oven to 500Â°F (or the highest temp your oven reaches less than 500Â°F). Pat the roast dry with paper towels (pre-salting should have made the roast release some moisture), and sprinkle the roast all over with salt and pepper. 4 Place the roast fat side up and rib bones down in a roasting pan.Insert a meat thermometer into the thickest part of the roast, making sure that the thermometer isn't touching a bone. 5 After browning the roast at a 500Â°F temperature in the oven for 15 minutes, reduce the oven temperature to 325Â°F.tâs called a standing rib roast because to cook it, you position the roast majestically on its rib bones in the roasting pan. Beautifully marbled with fat, this roast is rich, juicy, and tenderâa feast for the eyes and the belly. Itâs also very easy to cook.
