Best Answer: First of all to the guy above me, DNA is deoxyribonucleic acid, so it cant be made of itself. Next off, the rungs are made of bases. The bases are Adenine, Guanine, Cytosine, and Thymine. The sides are made up of a sugar molecule and a phosphate.Together the base, sugar, and phosphates make up a nucleotide, which is the subunit of DNA.n the carbon labeled #1 on the deoxyribose sugar, you have the base added to it. These bases form the rungs of the DNA molecule. Adenine, Thymine, Cytosine and Guanine are the four possible bases. There are two different types of bases, purines and pyrimidines.
Sweet Potatoes, often called âyamsâ, are a dicot (a plant having two embryonic seed leaves) and are from the Convolvulacea or morning glory family. Yams. Yams are closely related to lilies and grasses. Native to Africa and Asia, yams vary in size from that of a small potato to a record 130 pounds (as of 1999).
Yams are the source of the chemical diosgenin, a precursor of progesterone, cortisone, and other medically important steroids. The collection of plants for the production of diosgenin is licensed in several parts of the world. The true yam is about 20 percent starch and as a food is very similar to a potato.True yams (Dioscorea spp., Dioscoreaceae) are the third most important tropical root crop after cassava (Manihot esculenta, Euphorbiaceae) and sweet potato (Ipomoea batatas, Convolvulaceae).he water yam is a species from south-eastern Asia that is commonly cultivated. The Chinese yam, or Chinese potato, also known as cinnamon vine, is cultivated as an ornamental climbing vine but is also an important food plant; its thick tubers reach a length of about 1 m (3 ft).
