1) A particular triplet of bases in the template strand of DNA is 5' AGT 3'. The
corresponding codon for the mRNA transcribed is _____. - ANSWER A) 3' UCA 5'
2) The genetic code is essentially the same for all organisms. From this, one can
logically assume which of the following? - ANSWER A) A gene from an organism
can theoretically be expressed by any other organism.
3) The figure above shows a simple metabolic pathway. According to Beadle and
Tatum's hypothesis, how many genes are necessary for this pathway? - ANSWER
B) 2
4) Which of the following is directly related to a single amino acid? - ANSWER C)
the three-base sequence of mRNA
5) In the process of transcription, _____. - ANSWER B) RNA is synthesized
6) Codons are part of the molecular structure of _____. - ANSWER B) mRNA
7) What does it mean when we say the genetic code is redundant? - ANSWER D)
More than one codon can specify the addition of the same amino acid.
8) Once researchers identified DNA as the unit of inheritance, they asked how
information was transferred from the DNA in the nucleus to the site of protein
synthesis in the cytoplasm. What is the mechanism of information transfer in
eukarotes? - ANSWER B) Messenger RNA is transcribed from a single gene and
transfers information from the DNA in the nucleus to the cytoplasm, where protein
synthesis takes place.
9) According to the central dogma, what molecule should go in the blank? -
ANSWER C) mRNA
10) Codons are three-base sequences that specify the addition of a single amino
acid. How do eukaryotic codons and prokaryotic codons compare? - ANSWER D)
Codons are a nearly universal language among all organisms.
11) Which of the following occurs in prokaryotes but not in eukaryotes? - ANSWER
B) concurrent transcription and translation
12) Which of the following statements best describes the termination of transcription
in prokaryotes? - ANSWER B) RNA polymerase transcribes through the terminator
