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 is a. pyrimidine. Structure of RNA. Some RNAs are essentially completely single stranded (mRNAs for instance). Some RNAs have some double stranded regions (rRNAs & tRNAs). IN RNA, G BASE PAIRS WITH C AND A BASE PAIRS WITH U (URACIL).
