the direction of synthesis of an RNA transcript is
5′ to 3′
What is the process called that converts the genetic information stored in DNA to an RNA copy?
transcription
DNA does not store the information to synthesize which of the following
organelles
Transcription begins at a promoter. What is a promoter?
A site in DNA that recruits the RNA Polymerase
Which of the following statements best describes the promoter of a protein-coding gene?
the promoter is a nontranscribed region of a gene.
What determines which base is to be added to an RNA strand during transcription?
Base pairing between the DNA template strand and the RNA nucleotides
Which of the following terms best describes the relationship between the newly synthesized RNA molecule and the DNA template strand?
complementary
What happens to RNA polymerase II after it has completed transcription of a gene?
It is free to bind to another promoter and begin transcription.
Which of the following terms associated with transcription describe regions of nucleic acid?
promotor, gene, terminator
first transcription event
RNA polymerase binds promoter
second transcription event
RNA polymerase transcribes gene
third transcription event
RNA polymerase reaches terminator
last transcription event
RNA polymerase exits gene, RNA is released
A particular triplet of bases in the template strand of DNA is 5-AGT-3. What would be the corresponding codon for the mRNA that is transcribed?
3-UCA-5
Which of the following statements best describes the termination of transcription in prokaryotes?
RNA polymerase transcribes through the terminator sequence, causing the polymerase to separate from the DNA and release the transcript.
for any given gene, what ultimately determines which DNA strand serves as the template strand?
the base sequence of the gene’s promoter
What name is given to the process in which a strand of DNA is used as a template for the manufacture of a strand of pre-mRNA?
transcription
What name is given to the process in which the information encoded in a strand of mRNA is used to construct a protein?
translation
What name is given to the process in which pre-mRNA is edited into mRNA?
RNA processing
polypeptides are assembled from
amino acids
RNA processing converts the RNA transcript into
mRNA
During RNA processing a(n) _____ is added to the 5′ end of the RNA.
modified guanine nucleotide
During RNA processing a(n) _____ is added to the 3′ end of the RNA.
a long strand of adenine nucleotides

exons
translation occurs in the
cytoplasm
