What are the four bases that make up the rings of the DNA ladder?
DNA is made up of deoxyribose, phosphate, and nitrogen bases (adenine, thymine, cytosine, and guanine). The rungs of the ladder are made of two bases joined together with either two or three weak hydrogen bonds.
What are the rungs of the RNA ladder made of?
DNA ladder is made up of a phosphate group, 5-carbon sugar, and nitrogen bases. 5-carbon sugar is deoxiribose in DNA. these nitrogen bases are adenine, guanine, thymine, and cytosine. in these nitrogen bases, adenine bonds with thymine, and guanine bonds with cytosin. In this DNA ladder, the phosphate group and 5-carbon sugar act as two sides of the ladder and the middle of the ladder is nitrogen pair bases.-SALMA ABRAHIM(:
