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.
If using a gas grill, first brush the grill with vegetable oil to prevent sticking, preheat on high for 10-15 minutes with the lid down. This method of cooking works best with steaks that are 1 inch or thicker. Scrape the grill clean with a grill brush, leave one side on high and adjust the other side to medium heat.or example a 1 inch steak grilled to medium-rare would be 4-5 minutes on each side after the initial searing on high heat. Remove the steaks from the grill, tent with foil and let rest for 5 minutes, this helps to redistribute and retain more juices when sliced and promote a more even color throughout the meat.
