Explanation
Nucleotides are organic molecules that serve as the monomers, or subunits , of nucleic acids like DNA and RNA . The building blocks of nucleic acids, nucleotides are composed of a nitrogenous base , a five – carbon sugar (ribose or deoxyribose) and at least one phosphate group .
Hence cytocine, Guanine and Adenine will be present in nucleotide . But Tyrosine, is one of the 22 amino acids that are used by cells to synthesize protein. So it is not present in nucleotide.
Translation is the final step on the way from DNA to protien. It is the synthesis of protien directed by a mRNA template. The information conatined in the nucleotide sequence of the mRNA is read as three letter words (triplates), called codons. Each word stands for one amino acids.
Vitamin B6 refers to a group of chemically very similar compounds which can be interconverted in biological systems. Vitamin B6 is part of the vitamin B group, and its active form, pyridoxal 5'–phosphate (PLP) serves as a coenzyme in many enzyme reactions in amino acid, glucose, and lipid metabolism. Pyridoxine (PN), the form most commonly given as vitamin B6 supplement.
