Dr. Khorana and his colleagues synthesized an RNA molecule with repeating sequence of UGN bases (UG UG UG UG UG UG). IT produced a tetrapeptide with alternating sequence of cysteine and valine. It proves that codons for cysteine and valine are :

Nucleic acids are the biopolymers in which the repeating structural monomeric units is a nucleotide. The nucleotides structural monomeric unit is a nucleotide. The nucleotides consist of three components, a pentose sugar (D-(0)-" ribose or 2 - deoxy "-D-(-)-"ribose, heterocyclic base") , (purines i.e., adenine and guanine and pyrididines i.e., thymine, cytosine and uracil) and phosphoric acid. Sugar - base constitutes nucleosides. the two types of nucleic acids are DNA and RNA. Nucleic acids play significant role in replication and protein synthesis. If one of hte strands of DNA has the following sequence of bases in the 5' - 3' direction. 5'-A-G-T-C-A-A-G-3' Which base is closest to the 5' - end in the compementary strand?
