1. A scientist puts nucleotide chains of UUUUUU in a
test tube under conditions allowing protein synthesis. Soon
they are only amino acids chains of phenylalanine. What does
the experiment indicate?
(a) Proteins are made only from
phenylalanine
(b) Protein synthesis malfunctions in test
tubes
(c) Phenylalanine consists of uracil
(d) UUU codes for phenylalanine
2. During translation, the tRNA with a growing
polypeptide chain is always bound to which site?
(a) E site (b) P site (c) A site
3. Consider this mRNA strand.
5’ – AUGUUACUCGUCAACCUU – 3’
Which of the following would be the polypeptide chain it
codes for?
(a)
methionine-leucine-leucine-valine-asparagine-leucine
(b)
methionine-leucine-leucine-valine-asparagine-proline
(c)
methionine-isoleucine-leucine-valine-asparagine-leucine
(d)
methionine-leucine-leucine-valine-arginine-proline
