The basic building block of DNA is called a NUCLEOTIDE. A nucleotide is made up of one sugar molecule, one phosphate molecule and one of the four bases. Here is the structural formula for the four nucleotides of DNA. Note that the purine bases (adenine and guanine) have a double ring structure while the pyrimidine bases (thymine and cytosine) have only a single ring.
Medium. To prepare a medium steak on the grill, cook to an internal temperature of 160 degrees Fahrenheit. When you press the steak, it should feel slightly firm with a pink center and a grayish burn on the outside. As a general rule, cook a 1-inch steak to medium by leaving it on the grill for 2 to 3 minutes per side.ell Done. A well-done steak needs an internal temperature of 170 degrees Fahrenheit. To reach this internal temperature, you need to leave the steak on the grill for 4 to 5 minutes per side for a 1-inch steak or 8 to 9 minutes for a steak measuring 1 3/4 inches.
Here are some baby back ribs cooking on my gas grill. If you are cooking your ribs on a covered grill, then you need to use indirect heat, and monitor the temperature of your grill very closely. Get the grill stabilized at the correct temperature of 225Â° F (about 105Â° C) before putting the ribs on it.he trick to great ribs is to cook them very slowly with the BBQ sauce on them. You can do this in an oven, just set the temperature to 225Â° F (about 107Â° C). I occasionally use an electric smoker, which cooks at about 200 to 225 degrees Fahrenheit. I've also used this method on my gas grill and in my oven.
