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. 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.
Sear the rib roast for 15 minutes at the higher oven temperature (450Â°F), then turn the oven to the lower temperature (325Â° F) for the rest of the cooking time. Every 1/2 hour, baste the cut ends of the roast with the fat accumulated in the roasting pan.
