Detailed explanation-1: -There are three bases that are found in DNA and RNA: adenine, cytosine and guanine. Thymine is found exclusively in DNA, and is replaced by uracil exclusively in RNA.
Detailed explanation-2: -Each three-letter sequence of mRNA nucleotides corresponds to a specific amino acid, or to a stop codon. UGA, UAA, and UAG are stop codons. AUG is the codon for methionine, and is also the start codon.
Detailed explanation-3: -A codon is a DNA or RNA sequence of three nucleotides (a trinucleotide) that forms a unit of genomic information encoding a particular amino acid or signaling the termination of protein synthesis (stop signals).
Detailed explanation-4: -A nucleotide consists of a sugar molecule (either ribose in RNA or deoxyribose in DNA) attached to a phosphate group and a nitrogen-containing base.
