Updated.
Which of the following statements regarding a DNA double helix is true? - Answer The amount
of adenine is equal to the amount of thymine, and the amount of guanine is equal to the
amount of cytosine.
DNA replication - Answer uses each strand of a DNA molecule as a template for the creation of
a new strand.
When one DNA molecule is copied to make two new DNA molecules, the resulting DNA
molecules contain - Answer 50% of the parent DNA.
Multiple origins of replication on the DNA molecules of eukaryotic cells serve to - Answer
shorten the time necessary for DNA replication.
Which of the following enzymes catalyzes the elongation of a new DNA strand? - Answer DNA
polymerase III
Why does a DNA strand grow only in the 5ʹ to 3ʹ direction? - Answer because DNA
polymerases can only add nucleotides to the 3ʹ end of the growing molecule
The transfer of genetic information from DNA to RNA is called - Answer transcription
The directions for each amino acid in a polypeptide are indicated by a codon that consists of
________ nucleotides in an RNA molecule. - Answer three
We would expect that a 15-nucleotide sequence that includes a stop codon at the end (as part
of the 15-nucleotide sequence) will direct the production of a polypeptide that consists of -
Answer four amino acids
In the genetic code - Answer many amino acids are specified by more than one codon
, Which of the following occurs when RNA polymerase attaches to the promoter DNA? - Answer
initiation of a new RNA molecule
________ marks the end of a gene and causes transcription to stop. - Answer A terminator
Where do transcription and translation occur in prokaryotic cells? - Answer in the cytoplasm
Which of the following statements about eukaryotic RNA is true? - Answer Exons are spliced
together
Which of the following takes place during translation? - Answer the conversion of genetic
information from the language of nucleic acids to the language of proteins
Which of the following is a function of a tRNA molecule? - Answer joining to only one specific
type of amino acid
Considering only the steps that take place during translation, which of the following is not
needed in order for translation to occur? - Answer DNA template
Which of the following statements is false? - Answer The start codon can be different
depending on what kind of protein is to be translated
Which of the following options most accurately lists the sequence of events in translation? -
Answer codon recognition → peptide bond formation → translocation → termination
Which of the following statements regarding the flow of genetic information is false? - Answer
Transcription occurs in the cytoplasm of eukaryotic cells
What is the transcription product of the sequence GCTAGCGATGAC? - Answer
CGAUCGCUACUG
A eukaryotic cell has a nuclear envelope that allows tRNA molecules, but not mRNA molecules,
to leave the nucleus. Which of the following processes will not be able to take place in this cell?
- Answer tRNAs binding to codons
