Question
DMA whose genes have been purposely rearranged to contain new or different heredity information is called? Select one: a. gene therapy b. a mutation c. recombinant DNA d. genetic engineering There are 64 different codons that are composed of the four nucleotides (A, C, G and U). Which of the following statements is true? Select one: a. Each cod on codes for a unique amino acid b. Some amino acids are specified by multiple codons. c. Codons assembled in reverse order will code for the same amino acid. d. Seven codons will not code for an amino acid. These are called nonsense or termination codons. The three components of a nucleotide are?
