The color wheel is made up of three different types of colors - Primary, Secondary, and Tertiary. The primary colors are red, yellow, and blue. They are called primary for a couple of reasons. First, no two colors can be mixed to create a primary color.
RNA contains uracil and DNA Thymine. RNA has five bases, but DNA only four. DNA contains a deoxyribose sugar, but RNA contains ribose sugar. DNA is a double strand of nucleotides, but RNA a single strand.
uracil one of four types of nitrogenous bases found in RNA, having the single-ring structure of a class known as PYRIMIDINES. Formula: C4H4N2O2. See Fig. 310 . Uracil always forms complementary pairs with a base called adenine in DNA (during TRANSCRIPTION) or RNA (during TRANSLATION). uÂ·raÂ·cil (yÅ«r'Ä-sil)
