Question

A scientist puts nucleotide chains of uuuuuu in a test tube under conditions allowing protein synthesis. Soon the test tube is full of polypeptide chains composed only one the amino acid phenylalanine. What does this experiment indicate?

Answer 1

That UUU is triplet codon for the amino acid phenylalanine

Step-by-step explanation:

The genetic code is the set of rules used by cells to translate information from the genetic material into proteins. This occurs during the process of translation in which the ribosome links amino acids in an order specified by mRNA, using tRNA as a mediator. Three nucleotides in the mRNA that are read at a time are called codons. One codon specify one amino acid, but one amino acid can correspond to more then one codon.
