| Direction: Read the following and answer the questions from given below A codon is a trinucleotide sequence of DNA or RNA that corresponds to a specific amino acid. The genetic code describes the relationship between the sequence of DNA bases (A, C, G and T) in a gene and the corresponding protein sequence that it encodes. The cell reads the sequence of the gene in groups of three bases. There are 64 different codons out of which 61 specify amino acids while the remaining three are used as stop signals. So, each sequence of three codes for an amino acid and proteins are made up of sometimes hundreds of amino acids. So, the code that would make one protein could have hundreds, sometimes even thousands of triplets contained in it. |

A) CCU, CCC, CCA, CCG
B) CGU, CGC, CGA, CGG
C) GGU, GGC, GGA, GGG
D) ACU, ACC, ACA, ACG
