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?
The amino acid phenylalanine is composed of uracil.
UUU codes for the amino acid phenylalanine.
Protein synthesis malfunctions in test tubes.
Most proteins contain only one type of amino acid.

A diagram of a cellular process is shown above.
Which of the following identifies the process shown at point Z?
translation
translocation
replication
transcription
During transcription the DNA base sequence is transcribed into a complimentary mRNA sequence. A codon table like the one shown below lists the amino acids coded for by particular triads of mRNA bases. A segment of DNA has undergone a mutation in which one nucleotide has been changed. The original sequence was ACG and the new sequence is ACA. Use the codon table to determine whether or not this mutation will cause a change in the phenotype of the organism.
yes, the phenotype of the organism would change because a new amino acid will be coded for.
yes, the phenotype of the organism would change because any change in the DNA sequence will cause a change in phenotype.
Even though the DNA sequence changed, the sequence still codes for the same amino acid, so no change in phenotype will occur.
It is impossible to determine if a change in phenotype will occur using only the DNA sequence.
Which of the following carries amino acids to the site of protein synthesis?
mRNA

tRNA
