The bases of rna
WebMessenger RNA is always single stranded. It contains mostly the bases adenine, guanine, cytosine and uracil. The sequence of bases in mRNA molecules is complementary to the bases that constitute the genetic code. In messenger RNA, no base pairing takes place. In fact base pairing in the mRNA destroys its biological activity. WebThe building blocks of DNA are called nucleotides. There are four different types of nucleotide. The part of a nucleotide that can make it different from others is called the …

A base is an acid because it is a nitrogenous base. The phosphate group is not found in RNA. However, the two different bases are related. DNA and RNA are polynucleotides, which are long chain-like molecules made up of different types of nucleotides.
